Web User Control dynamically generated control events won’t fire.

I hope someone can give me a hand on this one.


This is what I am trying to do:


We need to create a report. We are using a Repeater control to generate a custom grid. The columns and data fields won’t be known until run-time.


I’ve created a WebUserControl which contains a repeater control.


At run-time, I dynamically create templates for the header and data items.

On the header template I want to use a LinkButton so that data can be sorted when the user clicks on one of the header columns.


In my Header Template class, I have a reference to a list of LinkButtons. This is the code for the InstantiateIn event:


public void InstantiateIn(Control container)


    //Add header fields

    foreach (LinkButton linkButton in _headerButtons)


      container.Controls.Add(new LiteralControl(
                           "<th scope=\"col\" nowrap=\"nowrap\">"));

      linkButton.Click += new EventHandler(linkButton_Click);


      container.Controls.Add(new LiteralControl("</th>"));


    container.Controls.Add(new LiteralControl("</tr>"));



  protected virtual void linkButton_Click(object sender, EventArgs e)


    throw new Exception("The method or operation is not implemented.");




The problem I am having is that the event for the link button does not fire.

I have also tried subscribing to the Repeater's ItemCommand event in the Web user control so that I can raise my own event, but the page posts back without calling the ItemCommand event.


I know I am missing something, I have just not found it yet.


Any help will be greatly appreciated it.

Hi J.C.

Double check where you are binding your controls. I've had issues like this before. Take a read of this it might help.


This is usually due to the control not being bound at the correct time during the button press post back. Take a look and let me know if it helped. If not contact me with the full code and I'll take a look.

Hope this helps

Custom User Controls and dynamically created web controls events not firing
I have a peculiar problem and since I am just starting to use .net I am confident I am doing something wrong, but I can't see it and I've wasted a lot of time so far trying to figure it out. Hopefully one of you can figure it out. I have a custom User Control and I am dynamically creating a RadioButtonList. If I remove the custom user control from the page the RadioButtonList works as expected and correctly. However, once I add the custom control, it does not fire the SelectedIndexChanged event. Below is some code. If all I do is remove: "<UC:TOPMENU id="TopMenu1"...

Server Web User Control or Web Custom Control
Ok, I made a DataGrid I like, stuck it in a Web Control Lib, and then to my toolbar. Now I want to take my nice little control and add it to a greater control, maybe place some buttons around it etc. I could always inherit from it in a new custom control and dynamically add the buttons, but I thought about using a Web User Control. I thought I could easily create a Web User Control, drop on my grid and the buttons on a form, and expose some properties and events, but once I got into it, I got a feeling that this isn't what a Web User Control is for. When designing a control li...

Dynamic User Control Inside Tab Control
I have a web aplication with one web form and one user control. The form contains a tabcontiner with NO tab panels. On each load, one tab panel is dynamically added to the web form and the user control is dynamically added to the tab panel. The user control contains a button. It raises an event on its click event.  Once you click on the button, the event is never called.

Custom Server Control Vs Web Parts, Any need for Custom Server Control
Hello I've just posted a similar question on why you need server controls when you can pre-compile usercontrols and redistribute them. http://forums.asp.net/p/1397433/3010100.aspx#3010100 I've seen lots of (usercontrol vs web part) but not much on web part vs custom server control. According to the MSDN site you can put web parts onto a normal asp.net page outside of a web part zone and they behave just like custom server controls. So, if you are creating a bunch of controls for redistribution to customer asp.net sites and/or SharePoint sites why don't you just create Web Par...
