scrollviewer not working in nested User Control

Posted By:      Posted Date: October 25, 2010    Points: 0   Category :WPF

The code below illustrates my problem: I cannot get the scrollbars in the embedded User Control (ucScroll1) to show up when I resize the main window (Window1) smaller.

It won't work even if I force the issue by defining it like this:
<ScrollViewer HorizontalScrollBarVisibility="Visible" VerticalScrollBarVisibility="Visible" IsEnabled="True" >

<UserControl x:Class="ScrollViewerApp.ucScroll1"



 Height="100" Width="300">

 <StackPanel VerticalAlignment="Top">

  <ScrollViewer HorizontalScrollBarVisibility="Auto" VerticalScrollBarVisibility="Auto" >

   <StackPanel Background="Aqua">

    <TextBox Width="100" Mar

Accessing a public property of a nested user control in a master page from a pages' user control

Hi  I've got a web site that has a master page and that master page (mpMaster that has a user control (ucControl1) which has a sub user control (ucControl2), this user control has a property which accepts a value. Now, I have a page that uses the master page and on this page I have another user control (ucPageControl), I need to  find a way of setting the value in ucControl2 from ucPageControl. Is this possible at all? Many thanks Ed

User Control Validation is not working properly

In my Website I have header control (header.ascx) and footer control (footer.ascx)In header.ascx one textbox and one button is there. Textbox meant for accepting search string.In footer.ascx one textbox and one button is there. Textbox meant for accepting Email-Id.Now in validation of header.ascx I had done blank checking by JavaScript. And in validation of footer.ascx  I had done blank-checking and e-mail checking by javascript.In both the control the textbox and the button both resides under Panel control whose DefaultButton property set to the respective button ids. So that if User write write something and press ENTER key from keyboard then it should do whatever respective Button_Clicks will do.Now My problem is suppose I place the mouse cursor in footer.ascx's textbox and press the ENTER key it validates properly but after that if I place the cursor inheader.ascx's textbox and press the ENTER then it is not working. Again If I do the opposite then also first one will fire but in case of second it is not firing .......

JQuery is not working on User Control



I have a user control, which contains a textbox and Jquery mask for a date format. When I have this code on aspx everything is fine, but when I migrate this to an ascx and run the code again, the mask isn't working. 

The JQuery and the Jquery plugin I am using I have placed on the ascx and then pushed it back to the aspx, but it doesn't work. What am I doing wrong?


Choosing Between a User Control or Web Part for SharePoint

SharePoint will only display Web Parts on a page. However, there are publicly available shims that allow you to write user controls and have them be displayed as a Web Part. From SharePoint's point of view, the shim is a Web Part. From the point of view of the user control, the shim is simply a control in .NET that is including the user control

Multiple Instances of User Control


I have a user control that I place on a page severl times.  When I make a selection on a ddl in one one control the SelectedIndexChanged event fires for all the control on the page for that ddl.  So I get duplication of an insert that I do.  Is there a way to make sure these events are isolated so this doesn't happen.

Persist data in a dynamically populated ListBox in a user control


Hi All,

I am trying to persist data in a dynamically populated ListBox in a user control. Here are the details

I have a user control which contains a a listBox and button. On Page_Load of user control I am populating the ListBox control with some values. On Click of button, I am trying to fetch the values which I have selected in ListBox. Though this seems very simple and straight forward I am unable to fetch values.

My Page_Load Function

void Page_Load(object sender, EventArgs e)










My Click Function

Protected Void Button1_Click(object sender, EventArgs e)


       string strValue = listBox.SelectedValue



I have placed brake point at Page_Load and on click function, I am seeing that the moment the breakpoin

Category attribute of user control property does not work correctly in categories tab.



I have a User Control (ascx) and a property which a want to display in my categories tab in Visual Studio in the category named "Styles".

[Category("Styles"), DefaultValue(""), Description("The value for formating something.")]
public String MyFormatProperty
set { /* the code for set */; }
get { /* the code for get */; }

And here is the problem: Actually I do not need a get, because I only have to set the property (write only property). But when I omit the get, the property is displayed in the "Misc" category in the categories tab in Visual Studio. Only when I code the get as well, then the property is displayed correctly in the "Styles" category in the categories tab in Visual Studio.

Does anybody know why? How can I display the category correctly only with set?

Thanks, S.

OnItemCommand not firing in Templated User Control


I have a templated user control with single instance template attribute. It works great for everything except the following scenario:


    <asp:UpdatePanel ID="upDirectoryBrowser" runat="server">

        <asp:AsyncPostBackTrigger ControlID="flsBrowser" EventName="FileSelected" />
        <asp:AsyncPostBackTrigger ControlID="flsBrowser" EventName="LinkSelected" />
        <table width="100%">
                <td style="width: 230px;">                        
                    <ntc:FolderSelector ID="fsBrowser" runat="server" OnFolderSelected="fsBrowser_FolderSelected"

"Type ASP.x is not defined" error for dynamic user control when publishing updateable


I have a user control (ContainerCtrl) which programmatically instantiates another user control (SimpleCtrl) in OnLoad. It builds and runs fine, but when I publish it I get the error "error BC30002: Type 'ASP.SimpleCtrl' is not defined." (If I publish without the "updateable" option there's no error, but I need the site to be updateable.)

I assume this has to do with the particulars of how the assembly(ies) are built for the different compiler options. My question is, how can I get it to work properly for "updateable" publishing?

VS 2008 / .NET 3.5 sp1

The code follows (web.config is the default from Visual Studio).

Many thanks, Dave


<%@ Control Language="VB" ClassName="SimpleCtrl" CodeFile="SimpleCtrl.ascx.vb" Inherits="_SimpleCtrl" %>

    Simple control


Partial Class _SimpleCtrl
    Inherits UserControl

    'Nothing to see here.

End Class


<%@ Control Language="VB" CodeFile="ContainerCtrl.ascx.vb" Inherits="_ContainerCtrl"

Localization not working in class library (composite control)



I have a class library called WEM.portal which used Resource files to localise text in my composite controls.

I store my resource files (eg MyResourceFile1.resx) in App_GlobalResources folder and then refer to them using

MyLabel1.text = My.Resources.MyResourceFile1.MyResourceKey1

This is all working ok until I create seperate files for each language such as MyResourceFile1.FR-fr.resx.

I have implemented this throughout my other web applications but the Class Library doesnt seem to want to work the same way

When I load the page it correctly showes the resourced keys which I have done through the web application BUT the resource keys in the composite controls does not seem to pick up the culture code.

Am I missing something stupid. Ive tried

  • changing the Build Action on the resource file to Content and Custom tool to GlobalResourceProxyGenerator
  • Creating a resourceManager but to no avail

GDI+: A Primer on Building a Color Picker User Control with GDI+ in Visual Basic .NET or C#


Although most developers and APIs use the RGB scheme when working with colors, it's not the only available way to represent or select colors. For instance, the standard Windows color-selection dialog box allows you to work with the HSL color scheme in an indirect way. In this article, the author describes several color selection schemes, and uses GDI+ (via the System.Drawing namespace) to create a component that makes it possible for your own applications to provide a simpler, friendlier color chooser. Along the way, you'll get tips to help you use GDI+ in your own apps.
