  • Help adding a backgroundView to UITableViewCell

    - by Alex
    I'm getting really desperate trying to add a UIImageView to UITableViewCell.backgroundView. All my efforts have resulted in this crappy rendering: It looks like the cell's label's white background is sitting on top of cell's background and covering portions of it. I tried setting the label's background color to clear, or some other color and it does not have any event. It is always white. The reason I know it's the text label's background causing this white area is that if I don't do [cell setText:@"Cell text here"]; the white area is gone and I see just the cell's background image. Here's the code that I'm using. The table view is added in the .xib file and UITableView is added to UIViewController: - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView { return 1; } - (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section { return [myCollection.items count]; } - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { NSUInteger rowIndex = indexPath.row; static NSString *CellIdentifier = @"Cell"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier]; if (cell == nil) { cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease]; cell.backgroundView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"darkCellBackground.png"]]; cell.selectedBackgroundView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"darkCellBackground.png"]]; } [cell setText:@"Cell text here"]; return cell; } - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath { // Navigation logic may go here. Create and push another view controller. // AnotherViewController *anotherViewController = [[AnotherViewController alloc] initWithNibName:@"AnotherView" bundle:nil]; // [self.navigationController pushViewController:anotherViewController]; // [anotherViewController release]; [tableView deselectRowAtIndexPath:indexPath animated:YES]; } - (BOOL)tableView:(UITableView *)tableView canEditRowAtIndexPath:(NSIndexPath *)indexPath { return NO; } I'm sure I'm doing something wrong but cant quite figure out what.

  • cakephp - form for belongsTo Model

    - by user1511579
    I createt the following model to link 2 relational tables: class Ficha extends AppModel { //public $useTable = 'ficha_seg'; var $primaryKey = 'id_ficha'; var $name = 'Ficha'; var $belongsTo = array( 'Perigo' => array( 'className' => 'Perigo', 'foreignKey' => false, 'conditions' => 'Perigo.id_fichas = Ficha.id_ficha' ) ); } Now, i have a form that requires data from the class Ficha, and then is redirected to another ctp page where i will input the data for the table "Perigos". However, since i'm still a newbie in cakephp i'm having difficult building that second form to insert the data on the table "Perigos". Here goes the code i built at the moment related to the second form: FichasController.php (the method where is it supposed to save the data on the table "Perigos": public function preencher_ficha(){ if ($this->request->is('ficha')) { $this->Ficha->create(); if ($this->Ficha->Perigo->save($this->request->data)) { $last_id=$this->Ficha->getLastInsertID(); $this->Session->setFlash('Your post has been updated '.$last_id.'.'); //$this->redirect(array('action' => 'preencher_ficha')); } else { $this->Session->setFlash('Unable to qualquer coisa your post.'); } } } The preencher_ficha.ctp file with the form: echo $this->Form->create('Ficha->Perigo', array('action' => 'index')); echo $this->Form->input('class_subst', array('label' => 'Classificação:')); echo $this->Form->input('simbolos_perigo', array('label' => 'Símbolos:')); echo $this->Form->input('frases_r', array('label' => 'Frases:')); echo $this->Form->end('Finalizar Ficha'); Here i guess the create part is wrong, but i think i have errors too in the controller part.

  • jQueryUI dialog width

    - by user35295
    Fiddle Full Screen Example I use jQuery dialog to open tables. Some of them have a large amount of text and they tend to be too long and go way off the screen. How can I make the dialog wider if the table is too long like the first one in the fiddle? I've tried width:'auto' but it seems to just occupy the entire screen. HTML: <button class='label'>Click</button><div class='dialog'><p><table>.....</table></div> <button class='label'>Click</button><div class='dialog'><p><table>.....</table></div> Javascript: $(document).ready(function(){ $('.label').each(function() { var dialogopen = $(this).next(".dialog"); dialogopen.dialog({width:'auto',autoOpen: false,modal: true, open: function(){ jQuery('.ui-widget-overlay').bind('click',function(){ dialogopen.dialog('close'); }) } }); $(this).click(function(){ dialogopen.dialog('open'); return false; } ); }); });

  • Repeater not working fine when passed a dataprovider (array) having a single element

    - by baltusaj
    I am using a Repeater in an Accordian which does not appear to see a single element in userArray. If I add another entry to userArray then the Repeater works fine. Thoughts?? private function currUsersServiceHandler(event:ResultEvent):void{ if (event.result.currentUsers != null) { if (event.result.currentUsers.user is ArrayCollection) // if more than one elements are present { usersArray = event.result.currentUsers.user; } else if (event.result.currentUsers is ObjectProxy) { //FIXIT usersArray populate by following line has some issue usersArray = new ArrayCollection(ArrayUtil.toArray(event.result.currentUsers)); } } } <mx:HTTPService id="currUsersService" url="currUsers.xml" result="currUsersServiceHandler(event)"/> <mx:Accordion includeIn="UserList" x="10" y="10" width="554" height="242" > <mx:Repeater id="rep" dataProvider="{usersArray}"> <mx:Canvas width="100%" height="100%" label="{rep.currentItem.firstName}" > <mx:HBox> <s:Label text="{rep.currentItem.firstName}"/> <s:Label text="{rep.currentItem.lastName}"/> <mx:/HBox> </mx:Canvas> </mx:Repeater> </mx:Accordian> Edit: There is another thing I have just noticed i.e. that the accordian does show a single tab (when Array has a single element) but it's not labeled with the first name which I am setting. If I enter another user, two tabs appear and both are labeled with names I am setting. The first tab appears labeled too then.

  • ASP.NET Custom/User Control With Children

    - by Bob Fincheimer
    I want a create a custom/user control that has children (NOT a template control). For Example, I want my control to have the following markup: <div runat="server" id="div"> <label runat="server" id="label"></label> <div class="field"> <!-- INSERT CHILDREN HERE --> </div> </div> and when I want to use it on a page I simply: <ctr:MyUserControl runat="server" ID="myControl"> <span>This is a child</span> <div>And another <b>child</b> </ctr:MyUserControl> The child controls inside my user control will be inserted into my user control somewhere. What is the best way to accomplish this. The functionality is similar to a asp:PlaceHolder but I want to add a couple more options as well as additional markup and the such. Also the child controls still need to be able to be accessed by the page.

  • Unable to `submit()` an html form after intercepting the submit with javascript.

    - by Ross Rogers
    I'm trying to intercept the submission of a form in order to change the value of my keywords label. I have the following code: <HTML> <FORM name="searchForm" method="get" action="tmp.html" > <input type="label" name="keywords" /> <input type="button" name="submit" value="submit" onclick="formIntercept();"/> </FORM> <SCRIPT language="JavaScript"> document.searchForm.keywords.focus(); function formIntercept( ) { var f = document.forms['searchForm']; f.keywords.value = 'boo'; f.submit(); }; </SCRIPT> </HTML> When I run this in chrome and click the submit button the keywords label changes to boo, but the javascript console says: Uncaught TypeError: Property 'submit' of object <#an HtmlFormElement> is not a function. How can I submit the form with the manipulated keywords?

  • How do I set a focus property on a TextInput that is built using AddChild?

    - by Huuuze
    I have the following MXML: <mx:State name="myState"> <mx:AddChild relativeTo="{myhbox}" position="after"> <mx:Box verticalAlign="middle" horizontalAlign="center" width="100%" height="100%"> <mx:Form id="myForm" width="479" verticalScrollPolicy="off" horizontalScrollPolicy="off"> <mx:FormItem label="My Label:" fontWeight="bold" id="myLabel" direction="vertical"> <mx:TextInput id="myTextInput" width="282" /> <mx:HBox> <mx:Button label="Go" click="go();" id="goButton" /> </mx:HBox> </mx:FormItem> </mx:Form> </mx:Box> </mx:AddChild> </mx:State> How do I set focus on the TextInput field using <mx:SetProperty/>? I've tried the following, but it only results in the field being highlighted -- the cursor does not appear in the TextInput: <mx:SetProperty target="{stage}" name="focus" value="{myTextInput}"/> Long story short, I want the cursor to appear in the field. UPDATE: I figured it out. See comments for solution.

  • Multi-model form problem

    - by raphael_turtle
    (I'm just learning rails so....) I have a photo model and a gallery model, habtm associations and a join table. I'm making a photo gallery. The gallery page has a title field and description field. User creates gallery title, then goes to the photo page and checkboxes each image they want in that gallery. I get the error "undefined method `to_i' for ["1", {"title"="1"}]:Array" when trying to save/update a photo with a gallery title(with the checkbox) <% form_for @photo, :html => {:multipart => true } do |f| %> <%= f.error_messages %> <p> <%= f.label :title %> <%= f.text_field :title %> </p> <p> <%= f.label :description %> <%= f.text_area :description %> </p> <p> <%= f.label :image %> <%= f.file_field :image %> </p> <% for gallery in @photo.galleries %> <% fields_for "painting[gallery_attributes][]", gallery do |g| %> <div> <%= g.check_box :title %> <%= gallery.title %> </div> <% end %> <% end %> <p><%= submit_tag 'Update' %></p> <% end %> How much of this is horribly wrong?

  • how to create a array of labelfields

    - by sheetal_r oswal
    I have 'n' number of data which has to be added to a label field which in turn has to be added to hfm.I am setting the single data in to label field as : final LabelField desc = new LabelField("", LabelField.FOCUSABLE); final LabelField desc1 = new LabelField("", LabelField.FOCUSABLE); Vector data = (Vector) listEvent.get(keys); for (int i = 0; i < data.size(); i++) { EventData ee = (EventData) data.elementAt(i); String Summary= ee.getSummary(); if (time.getText().equals(sTime)) { desc.setText(Summary); } else{ desc1.setText(Summary); } } HorizontalFieldManager horizontalFieldManager_left18 = new HorizontalFieldManager() { horizontalFieldManager_left18.add(desc1); vfm.add(horizontalFieldManager_left18); vfm.add(new SeparatorField()); HorizontalFieldManager horizontalFieldManager_left17 = new HorizontalFieldManager() { horizontalFieldManager_left17.add(desc); vfm.add(horizontalFieldManager_left17); vfm.add(new SeparatorField()); In the above code i loop over vector and set the data into labelfield and adding the label to hfm later. Now the case is the vector data has more than one summary data,and the data is getting overridden in labelfield,i need to keep 'n' number of summary data into lablefield and add to new hfm.

  • How to display controllers with proper aligning in iPhone screen ?

    - by chatcja
    I have a issue of displaying information in iPhone screen. Case is as follows. I crated a view-based application in Xcode name as myView. Then open myViewViewController.xib interface builder, change back groung color and added label at top-let (0, 0) of the view. Then I add new file named as myView2ViewController, which is subclass of UIViewController and corresponding XIB also generated. Open myView2ViewController in IB and added a label at top-left as previous. Also changed the background color. In the "applicationDidFinishLaunching" of AppDeligate do following myView2ViewController *mView = [[myView2ViewController alloc] initWithNibName:@"myView2ViewController" bundle:nil]; [window addSubview:mView.view]; When I run the application, it is shown as upper part of the Label is sheared. It seems as whole UI has been moved 20 px upper (Because, there is a horizontal space in the bottom). I guess this is due to some positioning. But still I could not found any way to fix it. Hope somebody will help me to identify this issue !!

  • undefined method `model_name' for NilClass:Class - Rails application

    So I have seen other articles here on stack about this and a lot of the time people are not doing @post = post.new. I read some where to use the plural...?? any ways I am getting this error on my discussion code: Discussion Controller class DiscussionsController < ApplicationController def index @discussion = Discussion.new @discussions = Discussion.all end def create @discussion = Discussion.create(params[:discussion]) if @discussion.save redirect_to tasks_path, :flash => {:success => 'Created a new discussion'} else redirect_to tasks_path, :flash => {:error => 'Failed to create a discussion'} end end end Discussion Form <%= form_for @discussion do |f| %> <p><%= f.label :title %> <%= f.text_field :title %></p> <p><%= f.label :content %> <%= f.text_area :content %></p> <% end %> Discussion Routes resources :discussions do resources :comments end Now as far as I know I am doing this right, because I have a task form set up essentially the same way - but I have looked at my code for hours and have googled and tried other examples and now i see this: undefined method `model_name' for NilClass:Class Extracted source (around line #1): 1: <%= form_for @discussion do |f| %> 2: 3: <p><%= f.label :title %> 4: <%= f.text_field :title %></p> Which should mean that I am missing something from my controller.....is it as asilly as a spelling mistake? .

  • <%: %> brackets for HTML Encoding in ASP.NET 4.0

    - by Slauma
    Accidentally I found this post about a new feature in ASP.NET 4.0: Expressions enclosed in these new brackets <%: Content %> should be rendered as HTML encoded. I've tried this within a databound label in a FormView like so: <asp:Label ID="MyLabel" runat="server" Text='<%: Eval("MyTextProperty") %>' /> But it doesn't work: The text property contains script tags (for testing), but the output is blank. Using the traditional way works: <asp:Label ID="MyLabel" runat="server" Text='<%# HttpUtility.HtmlEncode(Eval("MyTextProperty")) %>' /> What am I doing wrong? (On a sidenote: I am too stupid to find any information: Google refuses to search for that thing. The VS2010 Online help on MSDN offers a lot of hits, but nothing related to my search. Stackoverflow search too. And I don't know how these "things" (the brackets I mean) are officially called to have a better search term.) Any info and additional links and resources are welcome! Thanks in advance!

  • Using jQuery to POST Form Data to an ASP.NET ASMX AJAX Web Service

    - by Rick Strahl
    The other day I got a question about how to call an ASP.NET ASMX Web Service or PageMethods with the POST data from a Web Form (or any HTML form for that matter). The idea is that you should be able to call an endpoint URL, send it regular urlencoded POST data and then use Request.Form[] to retrieve the posted data as needed. My first reaction was that you can’t do it, because ASP.NET ASMX AJAX services (as well as Page Methods and WCF REST AJAX Services) require that the content POSTed to the server is posted as JSON and sent with an application/json or application/x-javascript content type. IOW, you can’t directly call an ASP.NET AJAX service with regular urlencoded data. Note that there are other ways to accomplish this. You can use ASP.NET MVC and a custom route, an HTTP Handler or separate ASPX page, or even a WCF REST service that’s configured to use non-JSON inputs. However if you want to use an ASP.NET AJAX service (or Page Methods) with a little bit of setup work it’s actually quite easy to capture all the form variables on the client and ship them up to the server. The basic steps needed to make this happen are: Capture form variables into an array on the client with jQuery’s .serializeArray() function Use $.ajax() or my ServiceProxy class to make an AJAX call to the server to send this array On the server create a custom type that matches the .serializeArray() name/value structure Create extension methods on NameValue[] to easily extract form variables Create a [WebMethod] that accepts this name/value type as an array (NameValue[]) This seems like a lot of work but realize that steps 3 and 4 are a one time setup step that can be reused in your entire site or multiple applications. Let’s look at a short example that looks like this as a base form of fields to ship to the server: The HTML for this form looks something like this: <div id="divMessage" class="errordisplay" style="display: none"> </div> <div> <div class="label">Name:</div> <div><asp:TextBox runat="server" ID="txtName" /></div> </div> <div> <div class="label">Company:</div> <div><asp:TextBox runat="server" ID="txtCompany"/></div> </div> <div> <div class="label" ></div> <div> <asp:DropDownList runat="server" ID="lstAttending"> <asp:ListItem Text="Attending" Value="Attending"/> <asp:ListItem Text="Not Attending" Value="NotAttending" /> <asp:ListItem Text="Maybe Attending" Value="MaybeAttending" /> <asp:ListItem Text="Not Sure Yet" Value="NotSureYet" /> </asp:DropDownList> </div> </div> <div> <div class="label">Special Needs:<br /> <small>(check all that apply)</small></div> <div> <asp:ListBox runat="server" ID="lstSpecialNeeds" SelectionMode="Multiple"> <asp:ListItem Text="Vegitarian" Value="Vegitarian" /> <asp:ListItem Text="Vegan" Value="Vegan" /> <asp:ListItem Text="Kosher" Value="Kosher" /> <asp:ListItem Text="Special Access" Value="SpecialAccess" /> <asp:ListItem Text="No Binder" Value="NoBinder" /> </asp:ListBox> </div> </div> <div> <div class="label"></div> <div> <asp:CheckBox ID="chkAdditionalGuests" Text="Additional Guests" runat="server" /> </div> </div> <hr /> <input type="button" id="btnSubmit" value="Send Registration" /> The form includes a few different kinds of form fields including a multi-selection listbox to demonstrate retrieving multiple values. Setting up the Server Side [WebMethod] The [WebMethod] on the server we’re going to call is going to be very simple and just capture the content of these values and echo then back as a formatted HTML string. Obviously this is overly simplistic but it serves to demonstrate the simple point of capturing the POST data on the server in an AJAX callback. public class PageMethodsService : System.Web.Services.WebService { [WebMethod] public string SendRegistration(NameValue[] formVars) { StringBuilder sb = new StringBuilder(); sb.AppendFormat("Thank you {0}, <br/><br/>", HttpUtility.HtmlEncode(formVars.Form("txtName"))); sb.AppendLine("You've entered the following: <hr/>"); foreach (NameValue nv in formVars) { // strip out ASP.NET form vars like _ViewState/_EventValidation if (!nv.name.StartsWith("__")) { if (nv.name.StartsWith("txt") || nv.name.StartsWith("lst") || nv.name.StartsWith("chk")) sb.Append(nv.name.Substring(3)); else sb.Append(nv.name); sb.AppendLine(": " + HttpUtility.HtmlEncode(nv.value) + "<br/>"); } } sb.AppendLine("<hr/>"); string[] needs = formVars.FormMultiple("lstSpecialNeeds"); if (needs == null) sb.AppendLine("No Special Needs"); else { sb.AppendLine("Special Needs: <br/>"); foreach (string need in needs) { sb.AppendLine("&nbsp;&nbsp;" + need + "<br/>"); } } return sb.ToString(); } } The key feature of this method is that it receives a custom type called NameValue[] which is an array of NameValue objects that map the structure that the jQuery .serializeArray() function generates. There are two custom types involved in this: The actual NameValue type and a NameValueExtensions class that defines a couple of extension methods for the NameValue[] array type to allow for single (.Form()) and multiple (.FormMultiple()) value retrieval by name. The NameValue class is as simple as this and simply maps the structure of the array elements of .serializeArray(): public class NameValue { public string name { get; set; } public string value { get; set; } } The extension method class defines the .Form() and .FormMultiple() methods to allow easy retrieval of form variables from the returned array: /// <summary> /// Simple NameValue class that maps name and value /// properties that can be used with jQuery's /// $.serializeArray() function and JSON requests /// </summary> public static class NameValueExtensionMethods { /// <summary> /// Retrieves a single form variable from the list of /// form variables stored /// </summary> /// <param name="formVars"></param> /// <param name="name">formvar to retrieve</param> /// <returns>value or string.Empty if not found</returns> public static string Form(this NameValue[] formVars, string name) { var matches = formVars.Where(nv => nv.name.ToLower() == name.ToLower()).FirstOrDefault(); if (matches != null) return matches.value; return string.Empty; } /// <summary> /// Retrieves multiple selection form variables from the list of /// form variables stored. /// </summary> /// <param name="formVars"></param> /// <param name="name">The name of the form var to retrieve</param> /// <returns>values as string[] or null if no match is found</returns> public static string[] FormMultiple(this NameValue[] formVars, string name) { var matches = formVars.Where(nv => nv.name.ToLower() == name.ToLower()).Select(nv => nv.value).ToArray(); if (matches.Length == 0) return null; return matches; } } Using these extension methods it’s easy to retrieve individual values from the array: string name = formVars.Form("txtName"); or multiple values: string[] needs = formVars.FormMultiple("lstSpecialNeeds"); if (needs != null) { // do something with matches } Using these functions in the SendRegistration method it’s easy to retrieve a few form variables directly (txtName and the multiple selections of lstSpecialNeeds) or to iterate over the whole list of values. Of course this is an overly simple example – in typical app you’d probably want to validate the input data and save it to the database and then return some sort of confirmation or possibly an updated data list back to the client. Since this is a full AJAX service callback realize that you don’t have to return simple string values – you can return any of the supported result types (which are most serializable types) including complex hierarchical objects and arrays that make sense to your client code. POSTing Form Variables from the Client to the AJAX Service To call the AJAX service method on the client is straight forward and requires only use of little native jQuery plus JSON serialization functionality. To start add jQuery and the json2.js library to your page: <script src="Scripts/jquery.min.js" type="text/javascript"></script> <script src="Scripts/json2.js" type="text/javascript"></script> json2.js can be found here (be sure to remove the first line from the file): http://www.json.org/json2.js It’s required to handle JSON serialization for those browsers that don’t support it natively. With those script references in the document let’s hookup the button click handler and call the service: $(document).ready(function () { $("#btnSubmit").click(sendRegistration); }); function sendRegistration() { var arForm = $("#form1").serializeArray(); $.ajax({ url: "PageMethodsService.asmx/SendRegistration", type: "POST", contentType: "application/json", data: JSON.stringify({ formVars: arForm }), dataType: "json", success: function (result) { var jEl = $("#divMessage"); jEl.html(result.d).fadeIn(1000); setTimeout(function () { jEl.fadeOut(1000) }, 5000); }, error: function (xhr, status) { alert("An error occurred: " + status); } }); } The key feature in this code is the $("#form1").serializeArray();  call which serializes all the form fields of form1 into an array. Each form var is represented as an object with a name/value property. This array is then serialized into JSON with: JSON.stringify({ formVars: arForm }) The format for the parameter list in AJAX service calls is an object with one property for each parameter of the method. In this case its a single parameter called formVars and we’re assigning the array of form variables to it. The URL to call on the server is the name of the Service (or ASPX Page for Page Methods) plus the name of the method to call. On return the success callback receives the result from the AJAX callback which in this case is the formatted string which is simply assigned to an element in the form and displayed. Remember the result type is whatever the method returns – it doesn’t have to be a string. Note that ASP.NET AJAX and WCF REST return JSON data as a wrapped object so the result has a ‘d’ property that holds the actual response: jEl.html(result.d).fadeIn(1000); Slightly simpler: Using ServiceProxy.js If you want things slightly cleaner you can use the ServiceProxy.js class I’ve mentioned here before. The ServiceProxy class handles a few things for calling ASP.NET and WCF services more cleanly: Automatic JSON encoding Automatic fix up of ‘d’ wrapper property Automatic Date conversion on the client Simplified error handling Reusable and abstracted To add the service proxy add: <script src="Scripts/ServiceProxy.js" type="text/javascript"></script> and then change the code to this slightly simpler version: <script type="text/javascript"> proxy = new ServiceProxy("PageMethodsService.asmx/"); $(document).ready(function () { $("#btnSubmit").click(sendRegistration); }); function sendRegistration() { var arForm = $("#form1").serializeArray(); proxy.invoke("SendRegistration", { formVars: arForm }, function (result) { var jEl = $("#divMessage"); jEl.html(result).fadeIn(1000); setTimeout(function () { jEl.fadeOut(1000) }, 5000); }, function (error) { alert(error.message); } ); } The code is not very different but it makes the call as simple as specifying the method to call, the parameters to pass and the actions to take on success and error. No more remembering which content type and data types to use and manually serializing to JSON. This code also removes the “d” property processing in the response and provides more consistent error handling in that the call always returns an error object regardless of a server error or a communication error unlike the native $.ajax() call. Either approach works and both are pretty easy. The ServiceProxy really pays off if you use lots of service calls and especially if you need to deal with date values returned from the server  on the client. Summary Making Web Service calls and getting POST data to the server is not always the best option – ASP.NET and WCF AJAX services are meant to work with data in objects. However, in some situations it’s simply easier to POST all the captured form data to the server instead of mapping all properties from the input fields to some sort of message object first. For this approach the above POST mechanism is useful as it puts the parsing of the data on the server and leaves the client code lean and mean. It’s even easy to build a custom model binder on the server that can map the array values to properties on an object generically with some relatively simple Reflection code and without having to manually map form vars to properties and do string conversions. Keep in mind though that other approaches also abound. ASP.NET MVC makes it pretty easy to create custom routes to data and the built in model binder makes it very easy to deal with inbound form POST data in its original urlencoded format. The West Wind West Wind Web Toolkit also includes functionality for AJAX callbacks using plain POST values. All that’s needed is a Method parameter to query/form value to specify the method to be called on the server. After that the content type is completely optional and up to the consumer. It’d be nice if the ASP.NET AJAX Service and WCF AJAX Services weren’t so tightly bound to the content type so that you could more easily create open access service endpoints that can take advantage of urlencoded data that is everywhere in existing pages. It would make it much easier to create basic REST endpoints without complicated service configuration. Ah one can dream! In the meantime I hope this article has given you some ideas on how you can transfer POST data from the client to the server using JSON – it might be useful in other scenarios beyond ASP.NET AJAX services as well. Additional Resources ServiceProxy.js A small JavaScript library that wraps $.ajax() to call ASP.NET AJAX and WCF AJAX Services. Includes date parsing extensions to the JSON object, a global dataFilter for processing dates on all jQuery JSON requests, provides cleanup for the .NET wrapped message format and handles errors in a consistent fashion. Making jQuery Calls to WCF/ASMX with a ServiceProxy Client More information on calling ASMX and WCF AJAX services with jQuery and some more background on ServiceProxy.js. Note the implementation has slightly changed since the article was written. ww.jquery.js The West Wind West Wind Web Toolkit also includes ServiceProxy.js in the West Wind jQuery extension library. This version is slightly different and includes embedded json encoding/decoding based on json2.js.© Rick Strahl, West Wind Technologies, 2005-2010Posted in jQuery  ASP.NET  AJAX

  • C# XmlSchemaSet - Resolving included schemas to enumerate attribute groups

    - by satixx
    Hi, I currently have a compiled XmlSchemaSet from which I get possible elements/attributes for each specific "parent" element defined in the schema. I have a single "master" xsd schema which includes another schema and uses attributeGroup references for some "common" elements. Here is a sample: (MasterSchema.xsd) <?xml version="1.0" encoding="utf-8"?> <xs:schema id="MasterSchema" xmlns:xs="http://www.w3.org/2001/XMLSchema" targetNamespace="CommonNamespace.xsd" xmlns="CommonNamespace.xsd" xmlns:mstns="CommonNamespace.xsd" elementFormDefault="qualified" > <xs:include schemaLocation="SourceAttributeGroups.xsd"/> <xs:element name="Binding" minOccurs="0" maxOccurs="2"> <xs:complexType> <xs:attribute name="Name" type="xs:string"/> <xs:attributeGroup ref="BindingSourceAttributeGroup"/> </xs:complexType> </xs:element> </xs:schema> (SourceAttributeGroups.xsd) <?xml version="1.0" encoding="utf-8"?> <xs:schema id="SourceAttributeGroups" xmlns:xs="http://www.w3.org/2001/XMLSchema" targetNamespace="CommonNamespace.xsd" xmlns="CommonNamespace.xsd" xmlns:mstns="CommonNamespace.xsd" elementFormDefault="qualified" > <xs:attributeGroup id="BindingSourceAttributeGroup" name="BindingSourceAttributeGroup"> <xs:attribute name="Source"> <xs:simpleType> <xs:restriction base="xs:string"> <xs:enumeration value="Data"/> </xs:restriction> </xs:simpleType> </xs:attribute> <!-- When Source is None --> <xs:attribute name="Value" type="xs:string"/> <!-- Label --> <xs:attribute name="Label" type="xs:string"/> </attributeGroup> </xs:schema> I would like to create an XmlSchemaSet in C# which would resolve, compile and "merge" every references of the MasterSchema so it would finaly look like this: (MasterSchema.xsd) <?xml version="1.0" encoding="utf-8"?> <xs:schema id="MasterSchema" xmlns:xs="http://www.w3.org/2001/XMLSchema" targetNamespace="CommonNamespace.xsd" xmlns="CommonNamespace.xsd" xmlns:mstns="CommonNamespace.xsd" elementFormDefault="qualified" > <xs:include schemaLocation="SourceAttributeGroups.xsd"/> <xs:element name="Binding" minOccurs="0" maxOccurs="2"> <xs:complexType> <xs:attribute name="Name" type="xs:string"/> <xs:attribute name="Source"> <xs:simpleType> <xs:restriction base="xs:string"> <xs:enumeration value="Data"/> </xs:restriction> </xs:simpleType> </xs:attribute> <!-- When Source is None --> <xs:attribute name="Value" type="xs:string"/> <!-- Label --> <xs:attribute name="Label" type="xs:string"/> </xs:complexType> </xs:element> </xs:schema> This way, I could traverse each XmlSchemaParticle of the compiled schema to get every single attribute for a specific element, even when its attributes are defined in an external schema. At the moment, when I get the possible attributes for a "Binding" element, I only get the "Name" attribute since it is originally defined in the "master" schema. What would be the possible solutions to this problem? Thanks! Satixx

  • Edit and render RichText

    - by OregonGhost
    We have an application (a custom network management tool for building automation) that supports printing labels that you can cut out and insert into the devices' front displays. In earlier versions of the tool (not developed in my company), the application just pushed the strings into an Excel file that the field technician could then manipulate (like formatting text). We didn't do this in the new version because it was hard (impossible) to keep the Excel file in sync, and to avoid a binding to an external application (let alone different versions of Excel). We're using PDFSharp for rendering the labels. It has a System.Drawing-like interface, but can output to a System.Drawing.Graphics (screen / printer) as well as to a PDF file, which is a requirement. Later, basic formatting was introduced like Font Family, Style, Size, Color which would apply to one label (i.e. to exactly one string). Now the customer wants to be able to apply these formats to single characters in a string. I think the easiest way would be to support a subset of RichText. It's not as easy as I thought though. Currently the editor just displays a TextBox for the label you want to edit, with the font set to the label's font. I thought I'd just replace it with RichTextBox, and update the formatting buttons to use the RichTextBox formatting properties. Fairly easy. However, I need to draw the text. I know you can get the RichTextBox to draw to a HDC or System.Drawing.Graphics - but as already said, I need it to use PDFSharp. Rendering to bitmaps is not an option, since the PDF must not be huge, and it's a lot of labels. Unfortunately I couldn't get the RichTextBox to tell me the layout of the text - I'm fine with doing the actual rendering by hand, as long as I know where to draw what. This is the first question: How can I get the properly layouted metrics of the rich text out of a RichTextBox? Or is there any way to convert the rich text to a vector graphics format that can be easily drawn manually? I know about NRTFTree which can be used to parse and manipulate RichText. The documentation is bad (actually I don't know, it's Spanish), but I think I can get it to work. As far as I understood, it won't provide layouting as well. Because of this, I think I'll have to write a custom edit control (remember, it's basically just one or two line labels with basic RTF formatting, not a full-fledged edit control - more like editing a textbox in PowerPoint) and write custom text layout logic that used PDFSharp rather than System.Drawing for drawing. Is there any existing, even if partial, solution available, either for the editing or for doing the layout manually (or both)? Or is there an entirely different approach I'm just not seeing? Bonus points if exporting the label texts as RTF into a CSV file, and then importing in Excel retains the formatting. For the editing part, I need it to work in Windows Forms. Other than that it's not Windows-Forms-related, I think.

  • Jquery datepicker popup not closing on select date in IE8

    - by Notorious2tall
    I've got a web form with a start date field. I've tied a jquery datepicker to the txt field. Now when I choose a date in FF, the selected date is populated in the text box and the calendar popup closes. However when I do the same thing in IE8, the selected date is populated in the text box but the popup remains open. I've also noticed that a script error is generated as soon as I select a date in the popup calendar. I'm using jquery 1.3.2, jquery-ui 1.7.2, and .NET 3.5. Here's an example of my code: <script type="text/javascript"> $(document).ready(function() { $("#<%=txtStartDate.ClientID%>").datepicker({ changeMonth: true, changeYear: true, showButtonPanel: true, showOn: 'button', buttonImage: '/_layouts/images/CALENDAR.GIF', buttonImageOnly: true }); }); </script> <div id="stylized"> <asp:ValidationSummary ID="vs" runat="server" CssClass="messages-error" HeaderText=" Action required before the form can be submitted." ForeColor="" ValidationGroup="sh" /> <div class="formrow"> <div class="ms-formlabel formlabel"> <asp:Label ID="lblStartDate" runat="server" CssClass="ms-standardheader" AssociatedControlID="txtStartDate">Start Date:</asp:Label> </div> <div class="ms-formbody formfield"> <asp:RequiredFieldValidator ID="reqStartDate" runat="server" ControlToValidate="txtStartDate" ErrorMessage="Start Date is a required field." Text="*" Display="Dynamic" ValidationGroup="sh"></asp:RequiredFieldValidator> <asp:CompareValidator ID="cvStartDate" runat="server" ControlToValidate="txtStartDate" ErrorMessage="Date must be in the format MM/DD/YYYY" Text="*" Display="Dynamic" ValidationGroup="sh" Operator="DataTypeCheck" Type="Date"></asp:CompareValidator> <asp:TextBox ID="txtStartDate" runat="server"></asp:TextBox> <span class="formMessage">ex. MM/DD/YYYY</span> </div> </div> <div id="buttonrow"> <asp:Button ID="btnSubmit" runat="server" Text="Submit" CssClass="ms-ButtonHeightWidth" OnClick="Submit_Click" ValidationGroup="sh" /> <asp:Button ID="btnCancel" runat="server" Text="Cancel" CssClass="ms-ButtonHeightWidth" OnClick="Cancel_Click" CausesValidation="false" /> </div> </div> Here's the script error I get in IE when I select the date: 'length' is null or not an object WebResource.axd Here's the code where the error is being thrown from: function ValidatorOnChange(event) { if (!event) { event = window.event; } Page_InvalidControlToBeFocused = null; var targetedControl; if ((typeof(event.srcElement) != "undefined") && (event.srcElement != null)) { targetedControl = event.srcElement; } else { targetedControl = event.target; } var vals; if (typeof(targetedControl.Validators) != "undefined") { vals = targetedControl.Validators; } else { if (targetedControl.tagName.toLowerCase() == "label") { targetedControl = document.getElementById(targetedControl.htmlFor); vals = targetedControl.Validators; } } var i; for (i = 0; i < vals.length; i++) { ValidatorValidate(vals[i], null, event); } ValidatorUpdateIsValid(); } It happens on the .length in the for loop at the end. Vals is null and isn't found in the previous if/else. I've stepped through the javascript and if (typeof(targetedControl.Validators) != "undefined") returns false and then if (targetedControl.tagName.toLowerCase() == "label") returns false too. Thus the length is null or not an object error. Now I'm not sure if the datepicker popup not closing in IE and the script error in the WebResources.axd file are related errors, but I'm leaning that way. Can anyone tell me why the popup isn't closing?

  • Why is AutoCompleteExtender not firing?

    - by Antoine
    Hi, I have some issue with the ASP AutoCompleteExtender control. I got one in my page that is working fine, but I have put another one in the same page, and I can't get it to work. Using HTTP Analyzer, no query is fired when I type into the textbox associated with it. Has anyone an idea? Both call the same webservice, with a different ContextKey parameter. The webservice cannot be the cause as it works in the first case (DevMgrTxtBox), and is not even called in the second (DevTxtBox). Properties of both controls are similar, I just changed the ID and targetControlID of the second. The code below is in a ContentPlaceHolder. I'm using VS2005 with .NET 2.0. AjaxControlToolkit.dll is in version 1.0.20229.0. EDIT: solution found. The ID is not the only thing that needs to be unique, the BehaviorID property must be unique too. Which wasn't documented. <tr> <td> <asp:Label ID="DevtMgrLbl" runat="server" Text="Development Manager"></asp:Label> </td> <td> <asp:UpdatePanel runat="server" id="devMgrPanel"> <contenttemplate> <asp:TextBox id="DevMgrTxtBox" runat="server"></asp:TextBox> <ajaxToolkit:AutoCompleteExtender id="AutoCompleteRole1" runat="server" CompletionSetCount="5" EnableCaching="true" BehaviorID="autoCompleteExtender" CompletionInterval="100" MinimumPrefixLength="2" ServiceMethod="GetRoleList" ServicePath="AutoCompleteRoles.asmx" TargetControlID="DevMgrTxtBox" ContextKey="DM"> </ajaxToolkit:AutoCompleteExtender> </contenttemplate> <triggers> <asp:AsyncPostBackTrigger ControlID="DevMgrTxtBox" EventName="TextChanged"></asp:AsyncPostBackTrigger> </triggers> </asp:UpdatePanel> </td> </tr> <tr> <td> <asp:Label ID="DevLbl" runat="server" Text="Developer"></asp:Label> </td> <td> <asp:UpdatePanel runat="server" id="devPanel"> <contenttemplate> <asp:TextBox ID="DevTxtBox" runat="server"></asp:TextBox> <ajaxToolkit:AutoCompleteExtender id="AutoCompleteRole2" runat="server" CompletionSetCount="5" EnableCaching="true" BehaviorID="autoCompleteExtender" CompletionInterval="100" MinimumPrefixLength="2" ServiceMethod="GetRoleList" ServicePath="AutoCompleteRoles.asmx" TargetControlID="DevTxtBox" ContextKey="DEV"> </ajaxToolkit:AutoCompleteExtender> </contenttemplate> <triggers> <asp:AsyncPostBackTrigger ControlID="DevTxtBox" EventName="TextChanged"></asp:AsyncPostBackTrigger> </triggers> </asp:UpdatePanel> </td> </tr>

  • integrating tinymce with asp .net MVC 4.0

    - by user1865670
    using ASP .NET MVC 4.0 , VS2012. In one of my page, I tried to integrate a WYSIWYG editor "TinyMCE". To integrate, I followed the following URL : .tugberkugurlu.com My view page is like : @model AboutModels @using FileUploadDemo.Models <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min.js"></script> <script src="Scripts/tinymce/jquery.tinymce.js" type="text/javascript"></script> @{ ViewBag.Title = "About"; } @using (Html.BeginForm()) { @Html.ValidationSummary(true) <fieldset> <legend>About</legend> <div class="editor-label"> @Html.LabelFor(model => model.Title) </div> <div class="editor-field"> @Html.EditorFor(model => model.Title) @Html.ValidationMessageFor(model => model.Title) </div> <div class="editor-label"> @Html.LabelFor(model => model.PostedOn) </div> <div class="editor-field"> @Html.EditorFor(model => model.PostedOn) @Html.ValidationMessageFor(model => model.PostedOn) </div> <div class="editor-label"> @Html.LabelFor(model => model.Tags) </div> <div class="editor-field"> @Html.EditorFor(model => model.Tags) @Html.ValidationMessageFor(model => model.Tags) </div> <div class="editor-label"> @Html.LabelFor(model => model.Content) </div> <div class="editor-field"> @Html.EditorFor(model => model.Content) @Html.ValidationMessageFor(model => model.Content) </div> <p> <input type="submit" value="Create" /> </p> <p> Posted Content : @ViewBag.HtmlContent </p> </fieldset> } Here my Model is like : public class AboutModels { public string Title { get; set; } public DateTime PostedOn { get; set; } public string Tags { get; set; } [UIHint("tinymce_jquery_full"), AllowHtml] public string Content { get; set; } } My about page loads with all features. "@html.EditorFor(model=>model.content)" also loads fine. but no "WYSIWYG" pane(i donno what it is called, the pane is used to edit my text written in the textarea(HTml.editorFor())) is loaded. In the runtime, Exception is thrown in jquery.tinymce.js file. Error Message : `Unhandled exception at line 86, column 11 in http://localhost:1706/Home/About 0x800a01b6 - Microsoft JScript runtime error: Object doesn't support this property or method` And give me two options, Continue or Break . If i continue, the page loads with features as i mentioned earlier. If i Break, then it stays in the jquery.tinymce.js file with a yellow text-background. I have no experience with Javascript/jquery. And new in ASP .NET MVC 4.0, actually this is my first try of web application in .net. I updated jquery from nuGet. What could be the possible ways to solve it?
