  • ASP.NET User Control Value

    - by Steven
    I created a DatePicker user control (ASP code below, no code behind) which is simply a textbox, image button, and a sometimes visible calendar. <%@ Control Language="vb" AutoEventWireup="false" _ CodeBehind="myDatePicker.ascx.vb" Inherits="Website.myDate" %> <%@ Register assembly="AjaxControlToolkit" namespace="AjaxControlToolkit" _ tagprefix="asp" %> <asp:TextBox ID="Date1" runat="server"></asp:TextBox> <asp:Image ID="Image1" runat="server" ImageUrl="~/Calendar_scheduleHS.png" /> <asp:CalendarExtender ID="Date1_CalendarExtender" runat="server" Enabled="True" TargetControlID="Date1" PopupButtonID="Image1" > </asp:CalendarExtender> Can I somehow tie or pass the value of the TextBox as the value of the whole control to use in the calling code?

  • Caching a user control

    - by Rishabh Ohri
    I have a user control which I want to Output cache( fragment cache) and set the dependency to a query. I mean that on change or modification of data returned by that query the cache should get invalidated. I have read that in the output cache directive in the user control Sqldependency = "CommandNotification" cannot be used. So, how should i proceed in order to add the sql query dependency to the fragment cached user control.

  • How do I encapsulate form/post/validation[/redirect] in ViewUserControl in ASP.Net MVC 2

    - by paul
    What I am trying to achieve: encapsulate a Login (or any) Form to be reused across site post to self when Login/validation fails, show original page with Validation Summary (some might argue to just post to Login Page and show Validation Summary there; if what I'm trying to achieve isn't possible, I will just go that route) when Login succeeds, redirect to /App/Home/Index also, want to: stick to PRG principles avoid ajax keep Login Form (UserController.Login()) as encapsulated as possible; avoid having to implement HomeController.Login() since the Login Form might appear elsewhere All but the redirect works. My approach thus far has been: Home/Index includes Login Form: <%Html.RenderAction("Login","User");%> User/Login ViewUserControl<UserLoginViewModel> includes: <%=Html.ValidationSummary("") % using(Html.BeginForm()){} includes hidden form field "userlogin"="1" public class UserController : BaseController { ... [AcceptPostWhenFieldExists(FieldName = "userlogin")] public ActionResult Login(UserLoginViewModel model, FormCollection form){ if (ModelState.IsValid) { if(checkUserCredentials()) { setUserCredentials() return this.RedirectToAction<Areas.App.Controllers.HomeController>(x = x.Index()); } else { return View(); } } ... } Works great when: ModelState or User Credentials fail -- return View() does yield to Home/Index and displays appropriate validation summary. (I have a Register Form on the same page, using the same structure. Each form's validation summary only shows when that form is submitted.) Fails when: ModelState and User Credentials valid -- RedirectToAction<>() gives following error: "Child actions are not allowed to perform redirect actions." It seems like in the Classic ASP days, this would've been solved with Response.Buffer=True. Is there an equivalent setting or workaround now? Btw, running: ASP.Net 4, MVC 2, VS 2010, Dev/Debugging Web Server I hope all of that makes sense. So, what are my options? Or where am I going wrong in my approach? tia!

  • UiElement from abstract class

    - by plotnick
    I placed a control into a grid. let's say the control is derived from public class 'ButBase' which is derived in its turn from System.Windows.Controls.Button. The code normally compiles and app works just fine. But there's something really annoying. When you try to switch to xaml-design tab it will say 'The document root element is not supported by the visual designer', which is normal and I'm totally okay with that, but the thing is, that all the xaml code is underlined and VS2010 says: 'Cannot create an instance of ButBase' although still normally compiles and able to run. I've tried the same code in VS2008, it said that needs to see a public parameterless constructor in the ButBase, and even after I put one it showed the same error. What do I miss here?

  • Handle tab key in ToolStripComboBox

    - by Jiri
    Hi, I have a ToolStripComboBox in a ToolStrip, and when I press TAB key in it, it gives focus to the next toolstrip button. I would like to change this behavior and give focus to a richtextbox on my form instead. The problem is that ToolStripComboBox does not have PreviewKeyDown event. And PreviewKeyDown of the hosting ToolStrip Toolbar is not called when tab key is pressed in the combo (just when pressed and some toolstripbutton is focused). TabStop of the toolstrip toolbar is false. Any ideas?

  • prevent the designer from calling a getter (VS 2008, WinForms)

    - by LLEA
    hi, I have a simple UserControl containing a ComboBox which is empty at first. The setter for that CB adds items to it and the getter returns the selected item. When adding this UC to a Form, the designer automatically calls the getter for the CB which is empty. The method to fill up the CB with items is called later. I can think of one or two ways to bypass this problem by "messing around" in the code. But before I start that I'd like to ask you if there is a way to stop the designer from calling the getter method. Maybe with a attribute similar to Browsable or Bindable? thx

(woow pretty awkward sentence tho) Thanks and Regards.. P.s : Can we use User controls as class in the way to return values ?

  • Relative path from an ASP.NET user control NavigateUrl

    - by Daniel Ballinger
    I have a user control that contains a GridView. The GridView has both a HyperLinkField column and a template column that contains a HyperLink control. The ASP.NET project is structured as follows, with the Default.aspx page in each case using the user control. Application Root Controls UserControl with GridView SystemAdminFolder Default.aspx Edit.aspx OrganisationAdminFolder Default.aspx Edit.aspx StandardUserFolder Default.aspx Edit.aspx Note: The folders are being used to ensure the user has the correct role. I need to be able to set the DataNavigateUrlFormatString for the HyperLinkField and the NavigateUrl for the HyperLink to resolve to the Edit.aspx page in the corresponding folder. If I set the navigate URL to "Edit.aspx" the URL in the browser appears as 'http://Application Root/Controls/Edit.aspx' regardless of the originating directory. I can't use the Web application root operator (~/) as the path needs to be relative to the current page, not the application root. How can I use the same user control in multiple folders and resolve the URL to another page in the same folder? Note: The question is strongly based off a similar question by azhar2000s on the asp.net forums that matches my problem.

  • How to implement DisplayMemberPath for my Wpf UserControl?

    - by Bevan
    I'm writing a WPF User Control for my application, wrapping a ListBox and a few other items. The ListBox has a new ItemTemplate that presents four pieces of information for each item in my list. I can hard code each of the four bindings to specific properties on my list items and they display fine. However, I want my UserControl to be a bit more flexible. On ListBox and ComboBox there is a property DisplayMemberPath (inherited from ItemsControl) that seems to "inject" the appropriate property binding into the standard ItemTemplate. How do I achieve the same result with my user control? I'd like to set up four new properties to allow configuration of the information displayed: public string LabelDisplayPath { get; set; } public string MetricDisplayPath { get; set; } public string TitleDisplayPath { get; set; } public string SubtitleDisplayPath { get; set; } Reviewing ItemsControl.DisplayMemberPath with Reflector seems to go down the rabbit hole, I haven't been able to fathom how it works. Also, if I'm completely off course - and there's another, more "WPF" technique that I should be using instead, please point me in that direction.

  • A control that contains multiple duplicate properties causing deadlock issues on IIS

    - by heads5150
    I am trying to work out if the above case is true for our site. I've been told by my hosting provider that this fix (http://support.microsoft.com/kb/974165) has to applied to our server due to performance issues. It basically describes an issues where UI code like: <asp:gridview id="GridView1" runat="server" ... PageSize="100" PagerSettings-Mode="Numeric" PagerStyle-BorderStyle="None" PagerStyle-BorderColor="Navy" PagerStyle-HorizontalAlign="Right" PagerSettings-PageButtonCount="2" PagerSettings-Position="Bottom"> <PagerStyle HorizontalAlign="Left" BorderColor="Navy" BorderStyle="None"></PagerStyle> ... <PagerSettings PageButtonCount="2"></PagerSettings> ... </asp:gridview> causing the following warning on the server "ISAPI 'C:\Windows\Microsoft.NET\Framework\v2.0.50727\aspnet_isapi.dll' reported itself as unhealthy for the following reason: 'Deadlock detected'." Does anybody know of a way that I can detect this issue in the build process or the debugger? Any help would be much appreciate.

  • C# UserControl Custom Properties

    - by kjward
    i am creating a usercontrol which provides all of the common validations for a range of textbox styles: alpha, number, decimal, SSN, etc. so, when a developer using this control selects the alpha style, they can also select another property which defines a string of special characters that could also be allowed during validation. but when the decimal style, for instance, is selected, i'd like to simply disable the special characters property so it is not settable when a style is selected that doesn't allow special characters. how can i achieve this goal? thanks

  • Animate UserControl in WPF?

    - by sanjeev40084
    I have two xaml file one is MainWindow.xaml and other is userControl EditTaskView.xaml. In MainWindow.xaml it consists of listbox and when double clicked any item of listbox, it displays other window (edit window) from EditView userControl. I am trying to animate this userControl everytime whenever any item from the listbox is double clicked. I added some animation in userControl however the animation only gets run once. How can i make my animation run everytime whenever any item from the listbox is clicked? <ListBox x:Name="lstBxTask" Style="{StaticResource ListBoxItems}" MouseDoubleClick="lstBxTask_MouseDoubleClick"> <ListBox.ItemTemplate> <DataTemplate> <StackPanel> <Rectangle Style="{StaticResource LineBetweenListBox}"/> <StackPanel Orientation="Horizontal"> <TextBlock Text="{Binding Taskname}" Style="{StaticResource TextInListBox}"/> <Button Name="btnDelete" Style="{StaticResource DeleteButton}" Click="btnDelete_Click"/> </StackPanel> </StackPanel> </DataTemplate> </ListBox.ItemTemplate> </ListBox> <ToDoTask:EditTaskView x:Name="EditTask" Grid.Row="1" Grid.RowSpan="2" Grid.ColumnSpan="2" Visibility="Collapsed"/> In the MainWindow code, there is mouse double click event, which changes the visibility of EditTaskView to Visible. Suggestions?

  • C# UserControl Validation

    - by Barry
    Hi, I have a UserControl with a Tab Control containing three tabs. Within the tabs are multiple controls - Datetimepickers, textboxes, comboboxes. There is also a Save button which when clicked, calls this.ValidateChildren(ValidationConstraints.Enabled) Now, I click save and a geniune validation error occurs. I correct the error and then click save again - valdiation errors occur on comboboxes on a different tab. If I navigate to this tab and click save, everything works fine. How can this be? I haven't changed any values in the comboboxes so how can the fail validation then pass validation? The comboboxes are bound to a dataset with their selectedValue and Text set. I just don't understand what is happening here. This behaviour also occurs for some textboxes too. The validation rule is that they have to be a decimal - the default value is zero, which is allowed. The same thing happens, they fail validation the first time - I make no changes, click save again and they pass validation. If you need any further information please let me know thanks Barry

  • How to add custom-control-derived TabItem to TabControl in WPF?

    - by orloffm
    I want to have my own base TabItem class and use other classes that derive from it. I define base class in MyNs namespace like this: public class MyCustomTab : TabItem { static MyCustomTab() { DefaultStyleKeyProperty.OverrideMetadata(typeof(MyCustomTab), new FrameworkPropertyMetadata(typeof(TabItem))); } } And this is what I do for the class that inherits from it: code-behind in MyNs namespace: public partial class ActualTab : MyCustomTab { public ActualTab() { InitializeComponent(); } } XAML: <MyCustomTab x:Class="MyNs.ActualTab" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"> <Grid> </Grid> </MyCustomTab> The error I get is "The tag 'MyCustomTab' does not exist in XML namespace 'http://schemas.microsoft.com/winfx/2006/xaml/presentation'". If I use TabItem tag in XAML the error says that it's not possible to define to different base classes. How to fix this?
