Hi,
I am experiencing the exact problem described in the following thread (http://www.telerik.com/community/forums/aspnet-ajax/combobox/target-for-the-callback-could-not-be-found.aspx)... I am loading a User Control dynamically from the masterpage's code behind and the included Combobox with EnableAutomaticLoadOnDemand = true fails on loading with the message: The target 'XXXXXXXXXXXXXXXXXXX' for the callback could not be found or did not implement ICallbackEventHandler.
Did you find a solution finally?
My UC code:
My UC code behind:
MasterPage code behind loads the UC with LoadControl. Masterpage also includes RadAjaxManager.
Thanks.

My UC code behind:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim sqlDS As New SqlDataSource
sqlDS.ConnectionString = connString 'Defined previously
sqlDS.SelectCommand = sqlQuery 'Defined previously
ProductList.DataSource = sqlDS
ProductList.DataBind()
End Sub
MasterPage code behind loads the UC with LoadControl. Masterpage also includes RadAjaxManager.
Thanks.
