  • How to create a MVC 2 DisplayTemplate for a field whose display format is dependent on another field

    - by Glenn
    If I have a property whose display format is dependent on the value of another property in the view model how do I create a display template for it? The combination of field1's display being dependent on field2's value will be used throughout the app and I would like to encapsulate this in a MVC 2 display template. To be more specific, I've already create a display template (Social.ascx) for custom data type Social that masks a social security number for display. For instance, XXX-XX-1234. [DataType("Social")] public string SocialSecurityNumber { get; set; } All employees also have an employeeID. Certain companies use the employee's social security number as either the whole employee id or as part of it. I need to also mask the employeeID if it contains the social. I'd like to create another display template (EmpID.ascx) to perform this task. [DataType("EmpID")] public string EmployeeID { get; set; } The problem is that I don't know how to get both properties in the "EmpID" template to be able to perform the comparison. Thanks for the help.

  • Using QTDesigner with PyQT and Python 2.6

    - by PyNewbie27
    Hi. I'm fairly new to Python and trying to work with the latest versions of QTDesigner, PyQT 4.7 and QT4.7 (I downloaded the whole package from PyQT4.7 website). I can't figure out how to make QTDesigner integrate closely with Python: ie. If I select "Form" View Code in QTDesigners menu, it errors saying "Unable to launch C:/Python26/Lib/site-packages/PyQT4/bin\uic." If I look in that directory there is a pyuic.py but not "uic". From searching online it seems this doesn't exist because it's expecting a C++ install instead of the python version. Is there anyway to make QTDesigner use/call pyuic.py to generate the code, then open an IDE or text editor of my choice to show me the PYTHON code generated by the QTDesigner-PyUIC chain? I'd like Designer to integrate closely with python, so I can make custom slots/signals in Designer while designing, then tweak the python code directly in my IDE later. If it is not possible to code directly inside QTDesigner using python, does that mean I have to hand code my programs entire UI directly in my PythonIDE? Using Designer directly would seemingly be nearly very very nice for a newbie such as myself, since I can see what properties each widget has and visually edit them while still learning the QT syntax without constantly having to use web resources to see what properties each widget should have and helps with boilerplate code generation, and what their defaults are, etc. I've googled and nobody seems to be using QTDesigner and Python in this manner together. It seems most are either handcoding all the QT code in their Python IDE of choice, or have found an obvious/easy method of doing what I want, therefore not really producing up to date tutorials on making this work together. Please enlighten me if you can. Thanks in advance for your time. Please include any suggestions you might have to a newbie trying to use Python with QT and QTDesigner. Thank you.

  • ExtJS GridPanel Scrollbar does not appear in IE7 but it does in Firefox, etc

    - by Snowright
    Setup I have an accordion layout containing a "properties" panel that nests two inner panels. The first inner panel holds a Ext.DataView, while the second panel is the Ext.grid.GridPanel in question. In the screenshot below, the white space containing the folder icon is the dataview, and below that is the gridpanel. Problem In Firefox, Chrome, and Opera, there is a scrollbar that appears when my gridpanel has an overflow of properties. It is only in Internet Explorer that it does not appear. I am, however, able to scroll using my mouse scroll button in all browsers, including IE. I've also tried removing our custom css file in case it was affecting it somehow, but there was no change in doing so. I'm not sure exactly what code I should show as I don't know where the exact problem is coming from but here is the code for the mainpanel and gridpanel. var mainPanel = new Ext.Panel({ id : 'main-property-panel', title : 'Properties', height : 350, autoWidth : true, tbar : [comboPropertyActions], items : [panel1] //panel1 holds the DataView }); var propertiesGrid = new Ext.grid.GridPanel({ stripeRows : true, height : mainPanel.getSize().height-iconDataView.getSize().height-mainPanel.getFrameHeight(), autoWidth : true, store : propertiesStore, cm : propertiesColumnModel }) //Add gridpanel to mainPanel mainPanel.add(propertiesGrid); mainPanel.doLayout(); Any help into the right direction would be greatly appreciated. Thank you.

  • jQuery autocomplete - update options on dynamically created elements

    - by Ian Robinson
    Background The user enters values into multiple inputs on the page. Think of entering a list of widgets for sale. The user would select the type of a widget from a drop down. Then enter the name of the Widget vendor, and then the actual name of the widget. These UI elements would all appear as one row. The user is able to click an "add another widget" link and a new row is created. The two input elements have autocomplete functionality attached to them using the DevBridge jQuery plugin. It suggests the name of the vendor and the name of the widget. I have recently wired up the logic to filter the name of the widget based on the name of the vendor you entered. This means setting the (custom) vendorName parameter when attaching the autocomplete plugin so it can be passed to the server side to retrieve the widget names for that vendor that match the name the user entered. To achieve this functionality I'm dynamically attaching the autocomplete functionality to the second element (the widget name text box) when it receives focus. Here is an example: $('.autocomplete-widget').live('focus', function () { $(this).autocomplete({ serviceUrl: '/something.ashx', params: { type: 'widget', vendorName: $(this).parent().prev().find('.autocomplete-vendor').val()} }); }); Problem At first glance, this looks to function quite well. However I started noticing some inconsistencies, and upon inspection, I found out that the call to the server is actually happening several times in some cases. Each time the widget name input element receives focus the autocomplete functionality is attached. And what I'm seeing is that the call to the server is made in proportion to how many times the input element has gained focus. I'd like to avoid making the call more than once, but retain the ability to attach (or update) the autocomplete functionality "on focus". I've tried to use the autocomplete 'setOptions' method but have only been able to get it to work with the static elements, not the dynamically created elements. Question Is there a way I can clear out the autocomplete functionality before I attach another one?

  • ASP.Net MVC2 (RTM) breaks response filtering - "Filtering is not allowed"

    - by womp
    I've just done a test run of upgrading a project to ASP.Net MVC 2 (RTM) in anticipation of the full official .Net 4.0 release coming later this month. Our application is using a minimizer for our CSS and javascript. To do so, it is making use of the HttpResponse.Filter property to set a custom filter. With the upgrade, the setter for this property is throwing an HttpException saying "Filtering is not allowed." Looking that the HttpResponse.Filter property in reflector shows this: set { if (!this.UsingHttpWriter) { throw new HttpException(SR.GetString("Filtering_not_allowed")); } ... private bool UsingHttpWriter { get { return ((this._httpWriter != null) && (this._writer == this._httpWriter)); } } Clearly something has changed in the way the HttpResponse is writing to the output stream in MVC2. Does anyone know what the change is, or at least a workaround for this? EDIT: This seems pretty radical. Some further investigation shows that ASP.Net MVC 2 RTM is using a System.Web.Mvc.ViewPage.SwitchWriter as the Output property of an HttpResponse, whereas MVC 1 was using a plain old HttpWriter. That explains why the exception is being thrown. But that doesn't explain why they've chosen to completely break this functionality. This thread seems to indicate that this is just temporary... but this makes me pretty nervous... this is the RTM after all. Any further comments appreciated on this.

  • jqGrid Coloring an entire line in Grid based upon a cells value

    - by Thomas
    Hi all, i know it's been asked before but i cant get it to run and i'm out of things to try. So i want to colorize a row in a Grid if its value is not 1 - i use a custom formatter for this. The formatter itself works, thats not the problem. I've tried multple ways I've found so far on the web - adding a class, directly adding css code, using setRowData, using setCell.... Here are my examples - none of them worked for me (linux, ff363) - any pointer would be gratly appreciated. 27.05.2010_00:00:00-27.05.2010_00:00:00 is my row id <style> .state_inactive { background-color: red !important; } .state_active { background-color: green !important; } </style> function format_state (cellvalue, options, rowObject) { var elem='#'+options.gid; if (cellvalue != 1) { jQuery('#list2').setRowData(options.rowID,'', {'background-color':'#FF6F6F'}); jQuery('#list2').setRowData('27.05.2010_00:00:00-27.05.2010_00:00:00', '',{'background-color':'#FF6F6F'}); for (var cnt=0;cnt<rowObject.length;cnt=cnt+1) { jQuery(elem).setCell(options.rowId,cnt,'','state_inactive',''); jQuery(elem).setCell('"'+options.rowId+'"',cnt,'','state_inactive'); jQuery(elem).setCell('"'+options.rowId+'"',cnt,'5', {'background-color':'#FF6F6F'},''); } } else { for (var cnt=0;cnt<rowObject.length;cnt=cnt+1) { jQuery(elem).setCell(options.rowId,cnt,'','state_active',''); } } <!-- dont modify, we simply added the class above--> return cellvalue; } Thanks, Thomas

  • How to populate a generic list of objects in C# from SQL database

    - by developr
    I am just learning ASP.NET c# and trying to incorporate best practices into my applications. Everything that I read says to layer my applications into DAL, BLL, UI, etc based on separation of concerns. Instead of passing datatables around, I am thinking about using custom objects so that I am loosely coupled to my data layer and can take advantage of intellisense in VS. I assume these objects would be considered DTOs? First, where do these objects reside in my layers? BLL, DAL, other? Second, when populating from SQL, should I loop through a data reader to populate the list or first fill a data table, then loop through the table to populate the list? I know you should close the database connection as soon as possible, but it seems like even more overhead to populate the data table and then loop through that for the list. Third, everything I see these days says use Linq2SQL. I am planning to learn Linq2SQL, but at this time I am working with a legacy database that doesn't have foreign keys setup and I do not have the ability to fix it atm. Also, I want to learn more about c# before I start getting into ORM solutions like nHibernate. At the same time I don't want to type out all the connection and SQL plumbing for every query. Is it ok to use the Enterprise DAAB for now?

  • Using RabbitMQ (Java client), is there a way to determine if network connection is closed during con

    - by MItch Branting
    I'm using RabbitMQ on RHEL 5.3 using the Java client. I have 2 nodes (machines). Node1 is consuming messages from a queue on Node2 using the Java helper class QueueingConsumer. QueueingConsumer consumer = new QueueingConsumer(channel); channel.basicConsume("MyQueueOnNode2", noAck, consumer); while (true) { QueueingConsumer.Delivery delivery = consumer.nextDelivery(); ... Process message - delivery.getBody() } If the interface is brought down on Node1 or Node2 (e.g. ifconfig eth1 down), the client (above) never knows the network isn't there anymore. Does RabbitMQ provide some type of configuration on the Java client that can be used to determine if the connection has gone away. Shutting down the RabbitMQ server on Node2 will trigger a ShutdownSignalException, which can be caught and the app can go into a reconnect loop. But bringing down the interface doesn't cause any type of exception to happen, so the code will be waiting forever on consumer.nextDelivery(). I've also tried using the timeout version of this call. e.g. QueueingConsumer consumer = new QueueingConsumer(channel); channel.basicConsume("MyQueueOnNode2", noAck, consumer); int timeout_ms = 30000; while (true) { QueueingConsumer.Delivery delivery = consumer.nextDelivery(timeout_ms); if (delivery == null) { if (channel.isOpen() == false) // Seems to always return true { throw new ShutdownSignalException(); } } else { ... Process message - delivery.getBody() } } but appears that this always returns true (even though the interface is down). I assume registering for the ShutdownListener on the connection will yield the same results, but haven't tried that yet. Is there a way to configure some sort of heartbeat, or do you just have to write custom lease logic (e.g. "I'm here now") in order to get this to work?

  • MVCContrib ActionFilter PassParametersDuringRedirect still passes reference type in querystring

    - by redsquare
    I am attempting to use the PRG pattern in an asp.net mvc 2 rc application. I found that the MVCContrib project has a custom action filter that will auto persist the parameters in TempData In an action I have the following return this.RedirectToAction(c => c.Requested(accountAnalysis)); however this is adding a querystring param to the request e.g http://mysite.com/account/add?model=MyProject.Models.AccountAnalysisViewModel Can anyone explain how I can use the PassParametersDuringRedirect filter attribute from MVCContrib to not pass the ViewModel type in the querystring. I see a patch was issued to fix this however in the latest MvcContrib that supports MVC 2 RC it is commented out as follows public static RedirectToRouteResult RedirectToAction<T>(this Controller controller, Expression<Action<T>> action) where T : Controller { /*var body = action.Body as MethodCallExpression; AddParameterValuesFromExpressionToTempData(controller, body); var routeValues = Microsoft.Web.Mvc.Internal.ExpressionHelper.GetRouteValuesFromExpression(action); RemoveReferenceTypesFromRouteValues(routeValues); return new RedirectToRouteResult(routeValues);*/ return new RedirectToRouteResult<T>(action); } Any help much appreciated.

  • Python Image Library, Close method

    - by DNN
    Hello, I have been using pil for the first time today. And I wanted to resize an image assuming it was larger than 800x600 and also create a thumbnail. I could do either of these tasks separately but not together in one method (I am doing a custom save method in django admin). This returns a "cannot identify image file" error message. The error is on the line "image = Image.open(self.photo)" after "#if image is size is greatet than 800 x 600 then resize image." I thought this may be because the image is already open, but if i remove the line I still get issues. So I thought I could try closing after creating a thumbnail and then reopening. But I couldn't find a close method.... This is my code: def save(self): #create thumbnail Thumb_Size = (75, 75) image = Image.open(self.photo) if image.mode not in ('L', 'RGB'): image = image.convert('RGB') image.thumbnail(Thumb_Size, Image.ANTIALIAS) temp_handle = StringIO() image.save(temp_handle, 'jpeg') temp_handle.seek(0) suf = SimpleUploadedFile(os.path.split(self.photo.name)[-1], temp_handle.read(), content_type='image/jpg') self.thumbnail.save(suf.name+'.jpg', suf, save=False) #if image is size is greatet than 800 x 600 then resize image. image = Image.open(self.photo) if image.size[0] > 800: if image.size[1] > 600: Max_Size = (800, 600) if image.mode not in ('L', 'RGB'): image = image.convert('RGB') image.thumbnail(Max_Size, Image.ANTIALIAS) temp_handle = StringIO() image.save(temp_handle, 'jpeg') temp_handle.seek(0) suf = SimpleUploadedFile(os.path.split(self.photo.name)[-1], temp_handle.read(), content_type='image/jpg') self.photo.save(suf.name+'.jpg', suf, save=False) #enter info to database super(Photo, self).save()

  • Android - Using PreferenceScreen to display and save settings to/from ContentProvider

    - by Donal Rafferty
    I have my own custom Content Provider that loads a datasbase which contains the settings information for my application. I load the settings from the ContentProvider on the creation of my Settings activity. My Settings activity is made up of a PreferenceScreen and Dialog based EditText's. The following code shows how I use the preference screen and edit texts. So as you can see from the first image this works and displays the menu with the information underneath. The problem is in image two, when I click on a choice in the menu the dialog pops up but it is empty, I would like to be able to load the data from my content provider into the edit text in the dialog, so in image one it shows "Donal" as the user name so in image two "Donal" should also appear in the edit text in the dialog. I would also like to be able to listen to the OK button in the dialog so when a user changes a setting I can update the data in my content provider. Can anyone help me with what I'm trying to do? Code // Root PreferenceScreen root = getPreferenceManager().createPreferenceScreen(this); // Dialog based preferences PreferenceCategory dialogBasedPrefCat = new PreferenceCategory(this); dialogBasedPrefCat.setTitle(R.string.dialog_based_preferences); root.addPreference(dialogBasedPrefCat); // Edit text preference EditTextPreference editTextPref = new EditTextPreference(this); editTextPref.setDialogTitle(R.string.dialog_title_edittext_preference); editTextPref.setKey("edittext_preference"); editTextPref.setTitle(R.string.title_edittext_preference); editTextPref.setSummary(name); dialogBasedPrefCat.addPreference(editTextPref); Image One Image Two

  • How do I make an ellipse blink?

    - by MedicineMan
    I am trying to make a custom control in WPF. I want it to simulate the behavior of a LED that can blink. There are three states to the control: On, Off, and Blinking. I know how to set On and Off through the code behind, but this WPF animation stuff is just driving me nuts!!!! I cannot get anything to animate whatsoever. The plan is to have a property called state. When the user sets the value to blinking, I want the control to alternate between green and grey. I'm assuming I need a dependency property here, but have no idea. I had more xaml before but just erased it all. it doesn't seem to do anything. I'd love to do this in the most best practice way possible, but at this point, I'll take anything. I'm half way to writing a thread that changes the color manually at this point. <UserControl x:Class="WpfAnimation.LED" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Height="300" Width="300"> <Grid> <Ellipse x:Name="MyLight" Height="Auto" Width="Auto"/> </Grid> </UserControl>

  • Get an IDataReader from a typed List

    - by Jason Kealey
    I have a List<MyObject> with a million elements. (It is actually a SubSonic Collection but it is not loaded from the database). I'm currently using SqlBulkCopy as follows: private string FastInsertCollection(string tableName, DataTable tableData) { string sqlConn = ConfigurationManager.ConnectionStrings[SubSonicConfig.DefaultDataProvider.ConnectionStringName].ConnectionString; using (SqlBulkCopy s = new SqlBulkCopy(sqlConn, SqlBulkCopyOptions.TableLock)) { s.DestinationTableName = tableName; s.BatchSize = 5000; s.WriteToServer(tableData); s.BulkCopyTimeout = SprocTimeout; s.Close(); } return sqlConn; } I use SubSonic's MyObjectCollection.ToDataTable() to build the DataTable from my collection. However, this duplicates objects in memory and is inefficient. I'd like to use the SqlBulkCopy.WriteToServer method that uses an IDataReader instead of a DataTable so that I don't duplicate my collection in memory. What's the easiest way to get an IDataReader from my list? I suppose I could implement a custom data reader (like here http://blogs.microsoft.co.il/blogs/aviwortzel/archive/2008/05/06/implementing-sqlbulkcopy-in-linq-to-sql.aspx) , but there must be something simpler I can do without writing a bunch of generic code. Edit: It does not appear that one can easily generate an IDataReader from a collection of objects. Accepting current answer even though I was hoping for something built into the framework.

  • UISplitViewController and complex view heirarchy

    - by Jasconius
    I'm doing an iPad tech demo and I'm running into a serious technical problem. I have an app concept that leverages UISplitViewController, but NOT as the primary controller for the entire app. The app flow could be described roughly as this: Home screen (UIViewController) List-Detail "Catalog" (UISplitViewController) Super Detail Screen (UIViewController but could conceivable also be a child of SplitView). The problem is in the flow between Home and Catalog. Once a UISplitViewController view is added to the UIWindow, it starts to throw hissy fits. The problem can be summarized at this: When a UISplitView generates a popover view, it appears to then be latched to its parent view. Upon removing the UISplitView from the UIWindow subviews, you will get a CoreGraphics exception and the view will fail to be removed. When adding other views (presumably in this case, the home screen to which you are returning), they do not autorotate, instead, the UISplitView, which has failed to be removed due to a CG exception, continues to respond to the rotation instead, causing horrible rendering bugs that can't be just "dealt with". At this point, adding any views, even re-adding the SplitView, causes a cascade of render bugs. I then tried simply to leave the SplitView ever present as the "bottom" view, and keeping adding and removing the Home Screen from on top of it, but this fails as SplitView dominates the Orientation change calls, and Home Screen will not rotate, even if you call [homeScreen becomeFirstResponder] You can't put SplitView into a hierarchy like UINavigationController, you will get an outright runtime error, so that option is off the table. Modals just look bad and are discourages anyway. My presumption at this moment is that the only proper way to deal with this problem is so somehow "disarm" UISplitViewController so that it can be removed from its parent view without throwing an unhandled exception, but I have no idea how. If you want to see an app that does exactly what I need to do, check out GILT Groupe in the iPad app store. They pulled it off, but they seem to have programmed an entire custom view transition set. Help would be greatly appreciated.

  • In Asp.Net MVC 2 is there a better way to return 401 status codes without getting an auth redirect

    - by Greg Roberts
    I have a portion of my site that has a lightweight xml/json REST API. Most of my site is behind forms auth but only some of my API actions require authentication. I have a custom AuthorizeAttribute for my API that I use to check for certain permissions and when it fails it results in a 401. All is good, except since I'm using forms auth, Asp.net conveniently converts that into a 302 redirect to my login page. I've seen some previous questions that seem a bit hackish to either return a 403 instead or to put some logic in the global.asax protected void Application_EndRequest() that will essentially convert 302 to 401 where it meets whatever criteria. Previous Question Previous Question 2 What I'm doing now is sort of like one of the questions, but instead of checking the Application_EndRequest() for a 302 I make my authorize attribute return 666 which indicates to me that I need to set this to a 401. Here is my code: protected void Application_EndRequest() { if (Context.Response.StatusCode == MyAuthAttribute.AUTHORIZATION_FAILED_STATUS) { //check for 666 - status code of hidden 401 Context.Response.StatusCode = 401; } } Even though this works, my question is there something in Asp.net MVC 2 that would prevent me from having to do this? Or, in general is there a better way? I would think this would come up a lot for anyone doing REST api's or just people that do ajax requests in their controllers. The last thing you want is to do a request and get the content of a login page instead of json.

  • Writing a docx file to a BLOB using Java 1.4 inside Oracle 10g

  • Core Data: Keypath "objectID" not found in entity

    - by Martin Gordon
    I'm using NSFetchedResultsController with a predicate to load a list of Documents in my application. I want to load all the Documents except the currently active one. I am using Rentzsch's MOGenerator to create a _Document class and then I put all my custom code in the Document subclass. _Document generates an objectID property with type DocumentID. In the class that creates the controller, I set the controller's currentDocID property: controller.currentDocID = self.document.objectID; In the controller itself, I lazy load the fetchedResultsController like this: - (NSFetchedResultsController *)fetchedResultsController { if (fetchedResultsController != nil) { return fetchedResultsController; } NSFetchRequest *fetchRequest = [[NSFetchRequest alloc] init]; NSEntityDescription *entity = [NSEntityDescription entityForName:@"Document" inManagedObjectContext:managedObjectContext]; [fetchRequest setEntity:entity]; NSPredicate *predicate = [NSPredicate predicateWithFormat:@"(objectID != %@)", self.currentDocID]; [fetchRequest setPredicate:predicate]; NSSortDescriptor *sortDescriptor = [[NSSortDescriptor alloc] initWithKey:@"dateModified" ascending:NO]; NSArray *sortDescriptors = [[NSArray alloc] initWithObjects:sortDescriptor, nil]; [fetchRequest setSortDescriptors:sortDescriptors]; NSFetchedResultsController *aFetchedResultsController = [[NSFetchedResultsController alloc] initWithFetchRequest:fetchRequest managedObjectContext:managedObjectContext sectionNameKeyPath:nil cacheName:@"Root"]; aFetchedResultsController.delegate = self; self.fetchedResultsController = aFetchedResultsController; [aFetchedResultsController release]; [sortDescriptor release]; [sortDescriptors release]; return fetchedResultsController; } When the fetchedResultsController loads, my app crashes with an unhandled exception: *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'keypath objectID not found in entity <NSSQLEntity Document id=1>' It's my understanding that all NSManagedObjects have an objectID, whether temporary or permanent. Is this not the case? Any thoughts?

  • Adding a modal view controller when I press a info button inside a tableviewCell

    - by gvalero87
    Hi, Here is a complex question, maybe it's not hard but there are many doubts i have. First let me give you what i have. This is the only place where i've gotten good answers. I have a table view controller with custom cells. In those cells i added a button (info dark one from IB) for each one of the cells. What i would like it's that when I press that button it displays a new view with more information about that cell, different of the view that i get from didSelectRowAtIndexPath. I've read a little bit about Modal View Controller and I think this is a case where I should use it. So here are my questions: How do i make a view controller a modal view controller?. I read that i have to have a delegate. Is there an example of how to create a normal modal view controller. I haven't been able to do so. How can this button know which cell is it from?. What i have right is a subclass tableviewcell with an IBOUTLET to this info button. This is not an important question because i guess i just could add a NSIndexPath attribute. I added an action in my tableviewsubclass that is triggered when the touchDown Event is called. I did this connection through IB. How can I call the modal view controller through here?, and is it even the right place to do this? Thanks

  • How to programmatically show & hide BalloonPopupExtender?

    - by Danferd
    I have a page that will be having few buttons that will redirect user to certain pages that required them to login before to proceed to the page. I would like to have something like, when user click on the button that required login and if user is not logged in prior to the click, a tooltip will show up beside the 'User ID' textbox to inform user to login in order to proceed. So, I implemented the jQuery Tooltipster in the page to show the tooltip message. I'm having problem on IE8 in Windows XP where the first click on the button, the tooltip would show up, but the second click it wouldn't then the third click, it shows up again and then the fourth click, it wouldn't! But for IE8 in Windows 7, IE9 & IE10, they have no such problem. Any idea how to fix this? The 'imgBtnKISS' & 'lnkBtnKISS' buttons are located in a content page but the tooltip and the 'User ID' textbox are in a master page. Below is the code that how I call the tooltip: function loginAlertMsg() { $('.tooltip').tooltipster({ trigger: 'custom', position: 'left', onlyOne: false, content: 'Login required! Please login to proceed.' }); $('#ctl00_txtID').tooltipster('show'); $('#ctl00_txtID').focus(); } Private Sub KISS_Click() Handles imgBtnKISS.Click, lnkBtnKISS.Click If Not bIsRefresh Then '==Detect User Login Status== Session(sesClickFromIcon) = toKISS If Session(USR.sesLogin) Is Nothing Then '//User NOT LOGIN. If (Not Page.ClientScript.IsStartupScriptRegistered("loginAlertMsg")) Then Page.ClientScript.RegisterStartupScript(Me.GetType(), "loginAlertMsg", "loginAlertMsg();", True) End If Exit Sub Else If Trim(CType(Session.Item(USR.sesLogin), Boolean)) <> True Then '//User NOT LOGIN. If (Not Page.ClientScript.IsStartupScriptRegistered("loginAlertMsg")) Then Page.ClientScript.RegisterStartupScript(Me.GetType(), "loginAlertMsg", "loginAlertMsg();", True) End If Exit Sub End If End If '**Detect User Login Status** Response.Redirect("~/page2.aspx", False) Session.Remove(sesClickFromIcon) End If End Sub

  • Android: Map Overlay Labels

    - by karnage
    I am building a MapView and I want my custom overlay items to display the name of the location they are marking when the user taps them, like the Android Maps app. I setup the onTap listener and the floating TextView to hold the location name. I still need to set it up so that it redraws the label when the user moves the map, etc. Anyway, I am wondering if I am reinventing the wheel here. Is there a built-in method I am unaware of? I would think that most implementations of MapView have labels. For reference, my implementation so far: in map xml: <LinearLayout android:id="@+id/mapBubbleWrap" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentTop="true"> <TextView android:id="@+id/mapBubble" android:layout_width="wrap_content" android:layout_height="wrap_content" android:visibility="gone" android:background="#ffffff" android:textColor="#ff0000"/> </LinearLayout> in my extended ItemizedOverlay: public boolean onTap(int index) { this.setFocus( mOverlays.get(index) ); return true; } in my Activity onFocus: public void onFocusChanged( ItemizedOverlay overlay, OverlayItem item ) { if( item != null) { mapBubble.setText(item.getTitle()); Point newPoint = mapView.getProjection().toPixels(item.getPoint(), null); mapBubbleWrap.setPadding(newPoint.x, newPoint.y-10, 0, 0); mapBubble.setVisibility(View.VISIBLE); } }

  • Problem with ScriptManager.RegisterStartupScript in WebControl nested in UpdatePanel

    - by Chris
    Hello, I am having what I believe should be a fairly simple problem, but for the life of me I cannot see my problem. The problem is related to ScriptManager.RegisterStartupScript, something I have used many times before. The scenario I have is that I have a custom web control that has been inserted into a page. The control (and one or two others) are nested inside an UpdatePanel. They are inserted onto the page onto a PlaceHolder: <asp:UpdatePanel ID="pnlAjax" runat="server"> <ContentTemplate> <asp:PlaceHolder ID="placeholder" runat="server"> </asp:PlaceHolder> ... protected override void OnInit(EventArgs e){ placeholder.Controls.Add(Factory.CreateControl()); base.OnInit(e); } This is the only update panel on the page. The control requires some initial javascript be run for it to work correctly. The control calls: ScriptManager.RegisterStartupScript(this, GetType(), Guid.NewGuid().ToString(), script, true); and I have also tried: ScriptManager.RegisterStartupScript(Page, Page.GetType(), Guid.NewGuid().ToString(), script, true); The problem is that the script runs correctly when the page is first displayed, but does not re-run after a partial postback. I have tried the following: Calling RegisterStartupScript from CreateChildControls Calling RegisterStartupScript from OnLoad / OnPreRender Using different combinations of parameters for the first two parameters (in the example above the Control is Page and Type is GetType(), but I have tried using the control itself, etc). I have tried using persistent and new ids (not that I believe this should have a major impact either way). I have used a few breakpoints and so have verified that the Register line is being called correctly. The only thing I have not tried is using the UpdatePanel itself as the Control and Type, as I do not believe the control should be aware of the update panel (and in any case there does not seem to be a good way of getting the update panel?). Can anyone see what I might be doing wrong in the above? Thanks :)

  • C# WPF XAML DataTable binding to relation

    - by LnDCobra
    I have 2 tables: COmpany {CompanyID, CompanyName} Deal {CompanyID, Value} And I have a listbox: <ListBox Name="Deals" Height="100" Width="420" Margin="0,20,0,0" HorizontalAlignment="Left" VerticalAlignment="Top" Visibility="Visible" IsSynchronizedWithCurrentItem="True" ItemsSource="{Binding}" SelectionChanged="Deals_SelectionChanged"> <ListBox.ItemTemplate> <DataTemplate> <StackPanel Orientation="Horizontal"> <TextBlock Text="{Binding companyRowByBuyFromCompanyFK.CompanyName}" FontWeight="Bold" /> <TextBlock Text=" -> TGS -> " /> <TextBlock Text="{Binding BuyFrom}" FontWeight="Bold" /> </StackPanel> </DataTemplate> </ListBox.ItemTemplate> </ListBox> As you can see, I want to display the CompanyName rather then the ID which is a foreign Key. The relation "companyRowByBuyFromCompanyFK" exists, as in Deals_SelectionChanged I can access companyRowByBuyFromCompanyFK property of the Deals row, and I also can access the CompanyName propert of that row. Is the reason why this is not working because XAML binding uses the [] indexer? Rather than properties on the CompanyRows in my DataTable? At the moment im getting values such as - TGS - 3 - TGS - 4 Any ideas? Edit: I still can't get this to work, What would be the best way to accomplish this? Make a converter to convert foreign keys using Table being referenced as custom parameter. Create Table View for each table? This would be long winded as I have quite a large number of tables that have foreign keys.

  • Could not find schema information for the element 'castle'.

    - by Richard77
    Hello! I'm creating a Custom tag in my web.config. I first wrote the following entry under the configSections section. <section name="castle" type="Castle.Windsor.Configuration.AppDomain.CastleSectionHandler, Castle.Windsor" /> But, when I try to create a castle node inside the configuration node as below <castle> <components> </components> </castle> I get the following error message:"*Could not find schema information for the element 'castle*'." "*Could not find schema information for the element 'components'***." Am I missing something? I can't find why. And, if I run the application anyway, I get the following error "Could not find section 'Castle' in the configuration file associated with this domain." Ps.// The sample comes from "Pro ASP.NET MVC Framework"/Steven Sanderson/APress ISBN-13 (pbk): 978-1-4302-1007-8" on page 99. Thank you for the help ============================================================ Since I believe to have done exactly what's said in the book and did not succed, I ask the same question in different terms. How do I add a new node using the above information? ============================================================================= Thank you. I did what you said and do not have the two warnings. However, I've go a big new warning: "The element 'configuration' in namespace 'MyWindsorSchema' has invalid child element 'configSections' in namespace 'MyWindsorSchema'. List of possible elements expected: 'include, properties, facilities, components' in namespace 'MyWindsorSchema'."

  • Access to DataTemplate Control of WPF Toolkit DataGridCell at Runtime, How?

    - by LukePet
    I have a DataGrid defined with WPF Toolkit. The CellEditingTemplate of this DataGrid is associated at runtime with a custom function that build a FrameworkElementFactory element. Now I have to access to control that is inserted inside DataTemplate of CellEditingTempleta, but I do not know how to do. On web I found a useful ListView Helper... public static class ListViewHelper { public static FrameworkElement GetElementFromCellTemplate(ListView listView, Int32 column, Int32 row, String name) { if (row >= listView.Items.Count || row < 0) { throw new ArgumentOutOfRangeException("row"); } GridView gridView = listView.View as GridView; if (gridView == null) { return null; } if (column >= gridView.Columns.Count || column < 0) { throw new ArgumentOutOfRangeException("column"); } ListViewItem item = listView.ItemContainerGenerator.ContainerFromItem(listView.Items[row]) as ListViewItem; if (item != null) { GridViewRowPresenter rowPresenter = GetFrameworkElementByName<GridViewRowPresenter>(item); if (rowPresenter != null) { ContentPresenter templatedParent = VisualTreeHelper.GetChild(rowPresenter, column) as ContentPresenter; DataTemplate dataTemplate = gridView.Columns[column].CellTemplate; if (dataTemplate != null && templatedParent != null) { return dataTemplate.FindName(name, templatedParent) as FrameworkElement; } } } return null; } private static T GetFrameworkElementByName<T>(FrameworkElement referenceElement) where T : FrameworkElement { FrameworkElement child = null; for (Int32 i = 0; i < VisualTreeHelper.GetChildrenCount(referenceElement); i++) { child = VisualTreeHelper.GetChild(referenceElement, i) as FrameworkElement; System.Diagnostics.Debug.WriteLine(child); if (child != null && child.GetType() == typeof(T)) { break; } else if (child != null) { child = GetFrameworkElementByName<T>(child); if (child != null && child.GetType() == typeof(T)) { break; } } } return child as T; } } this code work with the ListView object but not with the DataGrid object. How can use something like this in DataGrid?
