  • Unable to set row height for grid view

    - by GabrielHeng
    I tried to set a row height for each row of my grid view in visual studio. However, it does not work. The row height will not change according to the pixel that I typed in. Here is my codes. <asp:GridView ID="GridView1" runat="server" AllowPaging="True" AutoGenerateColumns="False" DataKeyNames="productID" DataSourceID="SqlDataSource1" BackColor="White" BorderColor="#CCCCCC" BorderStyle="None" BorderWidth="1px" CellPadding="4" ForeColor="Black" GridLines="Horizontal" Width = "850px" style="margin-bottom: 6px" RowStyle-Height="50px"> <AlternatingRowStyle Height="50px" /> <Columns> <asp:CommandField ButtonType="Button" ShowDeleteButton="True" ShowEditButton="True" /> <asp:BoundField DataField="productID" HeaderText="ProductID" ReadOnly="True" SortExpression="productID" /> <asp:BoundField DataField="title" HeaderText="Title" SortExpression="title" /> <asp:BoundField DataField="description" HeaderText="Description" SortExpression="description" /> <asp:BoundField DataField="price" HeaderText="Price" SortExpression="price" /> <asp:ImageField DataImageUrlField="image" HeaderText="Images" SortExpression="image" DataImageUrlFormatString="~/images/{0}"> </asp:ImageField> </Columns> <FooterStyle BackColor="#CCCC99" ForeColor="Black" /> <HeaderStyle BackColor="#333333" Font-Bold="True" ForeColor="White" /> <PagerStyle BackColor="White" ForeColor="Black" HorizontalAlign="Right" /> <SelectedRowStyle BackColor="#CC3333" Font-Bold="True" ForeColor="White" /> <SortedAscendingCellStyle BackColor="#F7F7F7" /> <SortedAscendingHeaderStyle BackColor="#4B4B4B" /> <SortedDescendingCellStyle BackColor="#E5E5E5" /> <SortedDescendingHeaderStyle BackColor="#242121" /> </asp:GridView> May someone help me with it? Thanks in advance.

  • Pass view to viewmodel with datatemplate

    - by jpsstavares
    I have a ParameterView and ParameterViewModel, and I need the ParameterViewModel to have a reference to the Parameter view (more on that later). In the window I have a list of ParameterViewModels and in the ResourceDictionary I add the DataTemplate: <DataTemplate DataType="{x:Type my:ParameterViewModel}" > <my:ParameterView HorizontalAlignment="Left"/> </DataTemplate> I then bind an ItemsControl.ItemSource to the List of ParameterViewModels The problem is: How can I pass the ParameterView to the ParameterViewModel in this scenario? The reason I need the ParameterView in the ParameterViewModel is the following: I have a TextBox whose Text property is binded to the PropertyModelView.Name property. But I want to display a default string when the Name is empty or Null. I've tried to set the property value to the default string I want when that happens but the TextBox.Text is not set in this scenario. I do something like this: private string _name; public string Name { get { return _name; } set { if (value == null || value.Length == 0) Name = _defaultName; else _name = value; } } I've also tried to specifically set the TextBox.Text binding mode to TwoWay without success. I think this is a defense mechanism to prevent an infinite loop from happening but I don't know for sure. Any help on this front would also be highly appreciated. Thanks, José Tavares

  • How to modify partial, depending on controller it's viewed from?

    - by user284194
    I'm using a partial from my "messages" controller in my "tags" controller. The portion in question looks like this: <% unless message.tag_list.nil? || message.tag_list.empty? %> <% message.tags.each do |t| %> <div class="tag"><%= link_to t.name.titleize, tag_path(t) %></div> <% end %> <% end %> Is there a way to hide this portion of the partial only when it is viewed from the "tags" controller?

  • iPhone SDK: problem managing orientation with multiple view controllers.

    - by Tom
    I'm trying to build an iPhone application that has two subviews in the main window. Each view has its own UIViewController subclass associated with it. Also, within each controller's implementation, I've added the following method: -(BOOL)shouldAutorotateToInterfaceOrientation: (UIInterfaceOrientation)interfaceOrientation { return YES; } Thus, I would expect both of the views to respond to changes in orientation. However, this is not the case. Only the first view added to the app's main window responds to orientation. (If I swap the order the views are added, then only the other view responds. In other words, either will work--but only one at a time.) Why is this? Is it not possible to handle the orientation changes of more than one view? Thanks! EDIT: Someone else had this question, so I'm copying my solution here: I was able to address this issue by providing a root view and a root view controller with the method "shouldAutoRotate..." and adding my other views as subviews to the root view. The subviews inherit the auto-rotating behavior, and their associated view controllers shouldn't need to override "shouldAutoRotate..."

  • C# Interface Method calls from a controller

    - by ArjaaAine
    I was just working on some application architecture and this may sound like a stupid question but please explain to me how the following works: Interface: public interface IMatterDAL { IEnumerable<Matter> GetMattersByCode(string input); IEnumerable<Matter> GetMattersBySearch(string input); } Class: public class MatterDAL : IMatterDAL { private readonly Database _db; public MatterDAL(Database db) { _db = db; LoadAll(); //Private Method } public virtual IEnumerable<Matter> GetMattersBySearch(string input) { //CODE return result; } public virtual IEnumerable<Matter> GetMattersByCode(string input) { //CODE return results; } Controller: public class MatterController : ApiController { private readonly IMatterDAL _publishedData; public MatterController(IMatterDAL publishedData) { _publishedData = publishedData; } [ValidateInput(false)] public JsonResult SearchByCode(string id) { var searchText = id; //better name for this var results = _publishedData.GetMattersBySearch(searchText).Select( matter => new { MatterCode = matter.Code, MatterName = matter.Name, matter.ClientCode, matter.ClientName }); return Json(results); } This works, when I call my controller method from jquery and step into it, the call to the _publishedData method, goes into the class MatterDAL. I want to know how does my controller know to go to the MatterDAL implementation of the Interface IMatterDAL. What if I have another class called MatterDAL2 which is based on the interface. How will my controller know then to call the right method? I am sorry if this is a stupid question, this is baffling me.

  • How add logic to Views? Ruby on Rails

    - by Gotjosh
    Right now I'm building a project management app in rails, here is some background info: Right now i have 2 models, one is User and the other one is Client. Clients and Users have a one-to-one relationship (client - has_one and user - belongs_to which means that the foreign key it's in the users table) So what I'm trying to do it's once you add a client you can actually add credentials (add an user) to that client, in order to do so all the clients are being displayed with a link next to that client's name meaning that you can actually create credentials for that client. What i can't figure it out how to do is, that if you actually have credentials in the database (meaning that there's a record in the users table with your client id) then don't display that link. Here's what i thought that would work <% for client in @client%> <h5> <h4><%= client.id %></h4> <a href="/clients/<%= client.id %>"><%= client.name %></a> <% for user in @user %> <% if user.client_id = client.id %> <a href="/clients/<%= client.id %>/user/new">Credentials</a> <%end%> <% end %> </h5> <% end %> And here's the controller: def index @client = Client.find_all_by_admin(0) @user = User.find(:all) end but instead it just puts the link the amount of times per records in the user table. Any help?

  • WPF List of ViewModels bound to list of Model objects.

    - by Eric
    In the model, I have: public ObservableCollection<Item> Items { get; private set; } In the ViewModel, I have a corresponding list of ItemViewModels: public ObservableCollection<ItemViewModel> ItemViewModels ... In the XAML, I will bind (in this case a TreeView) to the ItemViewModels property. My question is, what goes in the "..." in the ViewModel shown above? I am hoping for a line or two of code to binds these two ObservableCollections (providing the type of the ViewModel to construct for each model object). However, what I'm fearing is necessary is a bunch of code to handle the Items.CollectionChanged event and manually updates the ItemViewModels list by constructing ViewModels as necessary. Thanks! Eric

  • Typical Search, Result and Detail Workflow Staying Within an Android Tab

    - by Justin
    So, I've been banging my head looking for a good solution for a few days and am stuck. I have a search screen (Activity) in a tab, and after the user enters a value and clicks "search" I would like the results to come back in that same tab, and then if an item from the results is selected, to show more detailed results, in that same tab. I have it all working now in separate activities, and even the first step working in a tab, but as soon as I call the activity to process he search results... i.e. startActivity(i); for the results Activity, the results displayed are not in the tab! I am having a very difficult time getting this flow to work all under a tab. Any thoughts on how to make this happen? I keep hearing that Android views should be used instead of activities, but am I then to assume that all the logic I have right now for 3 activity needs to go inside 1 activity and then I need to handle setting the content and state for each of these cases? Plus, won't the history stack not work as pressing the back button will take the user out of the application, instead of taking them from say the search result to the search screen, or the details to the search results, etc. This seems like a mess. Can anyone show a more complex example of tabs or how one might have a simple search, result and detail workflow staying in a tab? I have seen a few questions on this concept of keeping activities "within a tab", but no good resolution. Please help.

  • Bind to a collection's view and just call ToString() in WPF

    - by womp
    I'm binding a GridView to a collection of objects that look like this: public class Transaction { public string PersonName { get; set; } public DateTime TransactionDate { get; set; } public MoneyCollection TransactedMoney { get; set;} } MoneyCollection simply inherits from ObservableCollection<T>, and is a collection of MyMoney type object. In my GridView, I just want to bind a column to the MoneyCollection's ToString() method. However, binding it directly to the TransactedMoney property makes every entry display the text "(Collection)", and the ToString() method is never called. Note that I do not want to bind to the items in MoneyCollection, I want to bind directly to the property itself and just call ToString() on it. I understand that it is binding to the collection's default view. So my question is - how can I make it bind to the collection in such a way that it calls the ToString() method on it? This is my first WPF project, so I know this might be a bit noobish, but pointers would be very welcome.

  • MVC JsonResult with the [Authorize] attribute going to Logon but not displaying the view

    - by likestoski
    I am seeing odd behavior with MVC 3 methods that return a JsonResult when used with the Authorize attribute. What looks like happens is the Authorize is correctly evaluated when I am not logged in but instead of redirecting to the logon form the Json response is the logon form. Is there an addition attribute that directs the response to not return a value but instead redirect the user to the logon form, preferebly with the correct returnUrl value? What I did as a demo was to setup a new MVC3 site and added AspNetMembership to my DB using the aspnet_regsql.exe command. All that is setup and logging me in correctly. The behavior of the JsonResult doesn't seem right and I'm hoping I have just missed an attribute to make it work properly. Any help is greatly appreciated, thanks in advance. Here is the Account Controller (leaving out the Post action which is not part of this question). public class AccountController : Controller { public ActionResult LogOn() { return View(); } [Authorize] public JsonResult AuthorizedAction() { return Json("Only returns if I am authorized"); } } Here is the Html markup: <script src="@Url.Content("~/Scripts/jquery-ui-1.8.11.min.js")" type="text/javascript"></script> <script type="text/javascript"> $(document).ready(function () { $("#btnTest").click(function () { $.ajax({ type: "POST", url: "Account/AuthorizedAction", data: {}, success: function (result) { $("#testMe").html(result); }, error: function (result) { $("#testMe").html('Something broke in the ajax request'); } }); }); }); </script> <input type="button" id="btnTest" value="Test me" /> <div id="testMe">I have initial text</div> The Result: 1) When logged in I get 'Only returns if I am authorized' in my test div 2) When not logged and I have a break point in my Logon() method I see this value Request["returnUrl"] "/Account/AuthorizedAction" The test div I have displays the logon form :) this seems like I'm just not handling this properly.

  • Codeigniter PHP - loading a view at an anchor point

    - by James Billings
    I have a form at the bottom of a long page, if a user fills out the form but it doesn't validate the page is reloaded in the typical codeigniter fashion: $this->load->view('template',$data); however because the form is way down at the bottom of the page I need the page to load down there like you do with HTML anchors. Does anyone know how to do this in codeigniter? I can't use the codeigniter redirect(); function because it loses the object and the validation errors are gone. Other frameworks I've used like Yii you can call the redirect function like: $this->redirect(); which solves the problem because you keep the object. I've tried using: $this->index() within the controller which works fine as a redirect but the validation errors are in another method which is where the current page is loaded from: $this->item($labs) but when I use this it get stuck in a loop Any ideas? I've seen this question a lot on the net but no clear answers. I'm researching using codeigniter "flash data" but think it's a bit overkill. cheers.

  • Navigation Controller with Tab Bar only on first view

    - by dinoc
    I am seeking advice on how to start my project. I need to use a combination of the navigation controller and tabbar controller but on the second screen, I need the tabbar controller not to be there. Here is a brief description of the two main screens Screen 1 will have a tabbar controller with two tabs. The first tab is a tableview and when you tap on a table cell, it drills down to Screen 2. The second tab is just a filter view that updates the table in the first tab of Screen 1. Screen two is just a details screen from the cells of Screen 1. The catch is that I don't want the TabBar on Screen 2. I am struggling with how to get started. Do I start with a Navigation-based application since I need to be able to drill down? How do I just add a tab bar to the main screen of the navigation based app? I can't start with a Tab Bar application because if I load a navigation controller inside one of the views of the tab controller, then when I drill down inside the nav controller, the tab bar still stays on the next screen when I need it to go away. Any help would be appreciated.

  • Pass 2-dimensional array trough view

    - by Mikael
    Hi, I'm trying to print a 2-dimensional array but can't figure it out. My controller uses this code: public ActionResult Test(string str) { DateTimeOffset offset = new DateTimeOffset(DateTime.Now); offset = offset.AddHours(-5); string[,] weekDays = new string[7,2]; for (int i = 0; i < 7; i++) { weekDays[i,0] = String.Format("{0:yyyy-MM-dd:dddd}", offset); //Date weekDays[i,1] = String.Format("{0:dddd}", offset); //Text offset = offset.AddHours(24); } weekDays[0,1] = "Today"; ViewData["weekDays"] = weekDays; return View(); } Now I wan't to print this array of weekdays as a dropdown-list and i thought this would work: <% foreach (var item in (string[,])ViewData["weekDays"]) { %> <option value=" <%= item[0] %> "> <%= item[1] %> </option> <% } %> But that's not the case, this code output just the first char of the string. So anyone got a suggestion? Thanks! /M

  • Show menu when view is long pressed

    - by swift1691
    I've been looking around on the internet regarding my question but I couldn't find a straight answer. Is it possible to create a non-blocking menu similar to the overflow menu found in Android 4.0+ when a view is long pressed? I have a number of LinearLayout instances which have an OnLongClickListener which brings up a context menu, but it's not exactly what I am looking for. I was hoping for a smoother menu which is brought up when one of these instances is clicked, and removed when the user clicks outside of the menu's region. This is very similar to the way the overflow menu behaves in the Android ActionBar. So to sum up, is it possible to replicate the look-and-fell and the behavior of the overflow menu when using context menus? Here's hoping I don't have to jump through hoops to get the implementation that I desire. Thanks in advance. EDIT: After some digging I've found the PopupMenu which is exactly what I was looking for however it works only on devices running Honeycomb and above. Does anyone know of a way with which I can replicate this menu behavior in older versions of Android without using blocking windows like dialogs?

  • Building a calendar navigation in Rails (controller and view links)

    - by user532339
    Trying to get the next month when clicking the link_to. I've done the following in the view. <%= form_tag rota_days_path, :method => 'get' do %> <p> <%= hidden_field_tag(:next_month, @t1) %> <%= link_to 'Next Month', rota_days_path(:next_month => @next_month)%> </p> <% end %> class RotaDaysController < ApplicationController # GET /rota_days # GET /rota_days.json # load_and_authorize_resource respond_to :json, :html def index @rota_days = RotaDay.all @hospitals = Hospital.all @t1 = Date.today.at_beginning_of_month @t2 = Date.today.end_of_month @dates = (@t1..@t2) #Concat variable t1 + t2 together # @next_month = Date.today + 1.month(params[: ??? ] #Old if params[:next_month] # @next_month = Date.today >> 1 @next_month = params[:next_month] + 1.month @t1 = @next_month.at_beginning_of_month @t2 = @next_month.end_of_month @dates = (@t1..@t2) end @title = "Rota" respond_to do |format| format.html # index.html.erb format.json { render json: @rota_days } end end I have identified that the reason why this may not be working is in because of the following in my controller @next_month = params[:next_month] + 1.month the last two called methods is defined only on time/date objects. but not on fixnum/string objects. I understand I am missing something from this Update I have found that the actual issue is that the `params[:next_month] is a string and I am trying to add a date to to it.

  • Display TableViews corresponding to segmentedControl in a single tableview without pushing a new view

    - by user1727927
    I have a tableViewController where I have used the Interface Builder to insert a Segmented Controller having two segments. Since by default, first segment is always selected, I am not facing any problem in displaying the tableview corresponding to first segment. However, when I click on the second segment, I want to display another tableView. Here goes the problem. I am calling newTableViewController class on clicking the second segment. Hence, this view is getting pushed instead. Please suggest me a method to have these two tableViews in the main tableView upon clicking the segments. I have used switch case for switching between the segments. Here's the relevant part of the code: This method is in the FirstTableViewController since first segment is by default selected. -(IBAction) segmentedControlChanged { switch(segmentedControl.selectedSegmnentIndex) { case 0: //default first index selected. [tableView setHidden:NO]; break; case 1: NewViewController *controller=[[NewViewController alloc] initWithNibName:@"NewViewController" bundle:nil]; self.navigationController pushViewController:controller animated:YES]; [controller release]; break; default: break; } }
