User Control and DataSourceID Property

Posted By:      Posted Date: August 24, 2010    Points: 0   Category :ASP.Net

I created a user control (.ascx) that contains a paging-user-control, a repeater and some other controls.
I want to use the property DataSourceID. How should I get the data from the datasource and when?
What is the recommended way?

I did it this way:
- Create a method to get the data by reflection, like:

private void PerformSelect()
	if (!String.IsNullOrEmpty(this.DataSourceID))
		Control control = Page.FindControl(this.DataSourceID);
		if (control == null)
			control = Parent.FindControl(this.DataSourceID);

		MethodInfo method = control.GetType().GetMethod("Select");
		IEnumerable data = (IEnumerable)method.Invoke(control, new object[0]);

		this.DataSource = data;
 - Call this method
In PageLoad when no postback
Changing the current page (paging-user-control)
Changing the current tab (tab-user-control)
Switching Visibility to true

I think that way is not the optimum, is there any better way?
Do you have any suggestions or links?

Thanks for your help, Andreas

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.

User Control as Composite Control Property


I have a composite control (Called Dialog) which has a property "ContentControl"

At design time, I'd like this property to bind to a user control that is on the page.

When I add the items in the designer, the designer loads as expected.

However, when I try to run the web page, I get the following error:

Parser Error Message: Cannot create an object of type 'System.Web.UI.UserControl' from its string representation 'EditTerm1' for the 'ContentControl' property.

Please let me know if there is another way to bind a user control as a property of a composite control.


Designer Code:


	<cc1:Dialog ID="Dialog1" runat="server" Buttons="SaveCancel" 
Title="Edit Term" ContentControl="EditTerm1" />

Dynamic Binding of a Public Property in a User Control

Hi, I am not sure how to pass a variable from an .aspx page to an .ascx page.  I have a Control that puts rotating banners on a page.  The control has several public properties.  However, only one of those properties changes on the page level.  All the other properties are the same for every page site-wide.  So, instead of setting all the properties on every page in my sites (many sites), I want to set it up so I only have to setup the sitewide properties once and only the page level properties on each page.   I want to create a control with a property of AdKeyword="somename" and pass it to another control that will grab that page-level property and add it to all the other site-wide properties.  I guess what I need could be called a Dynamic Control Property.   My .aspx page has:<%@ Register TagPrefix="uc1" TagName="Banner1" Src="banner1.ascx" %> <asp:Content ID="Leaderboard" runat="server" ContentPlaceHolderID="Leaderboard"> <uc1:Banner1 AdKeyword="L2Chamber" runat="server" OverrideHeight="90" /> </asp:Content> My banner1.ascx page has:<%@ Control Language="VB" ClassName="UserControl297" %> <%@ register tagprefix="uc1&

Problem with property editor of a web user control



I created an asp.net user control with a property named 'TabList' , the property is visible when I place my control on a page, the default editor for this property was a simple text box, but I needed a DropDownList for editing the TabList property of my control, so I added following code to implement it:

<Category("Navigation Bar"), Editor(GetType(DropDownList), GetType(System.Drawing.Design.UITypeEditor)), Description("List of Tabs"), DefaultValue("SHISHIR WAHI")> Public Property TabList() As String
            Return _tablist
        End Get

        Set(ByVal value As String)
            _tablist = value
        End Set
    End Property

The Category() and DefaultValue() are working fine but Editor() and Description() are not, what could be the problem?

Please help.

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.


how to get an array of all the asp.net textbox control inside create user wizard control?



How can I get all the textboxes inside a create user wizard control using getElementsByTagName().

Below is my JQuery code:

<script type="text/javascript">
        function addLoadEvent(func) {
            var oldonload = window.onload;
            if (typeof window.onload != 'function') {
                window.onload = func;
            } else {
                window.onload = function() {

        function prepareInputsForHints() {
            var inputs = document.getElementsByTagName("asp:TextBox");
            for (var i = 0; i < inputs.length; i++) {
                inputs[i].onfocus = function() {
                    this.parentNode.getElementsByTagName("span")[0].style.display = "inline";

Custom Server Control Property not maintaining state


I have created a server control consisting of a TextArea and a div under it.  My goal is to create my own asp:TextArea type control.  the div is for a Character count of the text area and seems to work ok but i added a CharacterCountVisible property to the control that is always returning true.  See Proptery definition below


<Bindable(False), Category("Appearance"), DefaultValue("True"), Localizable(True)> Property CharacterCountVisible() As Boolean
        Return _CountBoxVisible
    End Get
    Set(ByVal value As Boolean)
        _CountBoxVisible = value
    End Set
End Property

Note the _CountBoxVisible variable is define inside the class as :

Dim _CountBoxVisible as Boolean = True

What I am trying to do is give the user/coder the option to show/utilize the char count feature.  Can make it disappear with textarea1.CharacterCountVisible = False but setting it to true will not make it display.

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

"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

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.

Passing Primary Key to User Control to Display Record Detail


I'm building a user control to display detail information on a parent record. The user control will be displayed via an Ajax Modal Popup. The user control works and is displayed when expected. The problem that I'm having is that I'm not able to pass in the primary key for the parent. The control is displayed via the _ItemCommand event of a Repeater. In the markup for the user control, I explicity set the ContactId to 0 to avoid an error when the control loads (its still underdevelopment, eventually that I'll check if the value is valid).

I was assuming that I could change the property in the _ItemCommand event, but obviously its not working.

In the Page_Load event this code successfully sets the ContactId property of the control. The _ItemCommand event appears to set the value. However when I set a test label on the user control to the Me.ContactId, its showing '0' as if it was never passed in.

        UserControlContactDetail.ContactId = "1462"
        test.Text = UserControlContactDetail.ContactId

    Protected Sub RepeaterDirectory_ItemCommand(ByVal source As Object, ByVal e As System.Web.UI.WebControls.RepeaterCommandEventArgs) Handles RepeaterDirectory.ItemCommand
