AutoCompleteBox add control programmatically error

[Giang]

I have:
1. An user control: Pub.ascx. The user control has a RadAutoCompleteBox. I bind data for the RadAutoCompleteBox in Page_Load event of Pub.ascx.
2. A webpage: Test.aspx. The page has a button btnAdd and a panel pnlPubs. When I click on Add, the page load user control Pub.ascx then add it to the panel pnlPubs.

Now I can see the user control Pub.ascx on the panel. However, when I try to use the RadAutocompleteBox, it shows me error:
"The target 'ctl02$rbConf' for the callback could not be found or did not implement ICallbackEventHandler."

Would you please help me solving this problem? I really need to add AutoCompleteBox programmatically.

Thank you.

Hello Giang,

When a control is added dynamically, it's not persisted across postbacks/callbacks which is the reason for the experienced behavior. Here is a forum thread discussing the same problem, but with a RadComboBox control.

Hello Arwad,

The provided screenshot does not provide sufficient information about the reason for the experienced problem. Could you share a bit more information about your particular scenario, the declaration of the control and the way its been populated?
