[Solved] Ajaxpanel in codebehind

[Andres]

Hi!

We are trying to use the radajax panel from codebehind.  Using the rendercontrol method we can't get the ajaxpanel to work.  We always have the  following error:

 Script control 'upCats' is not a registered script control. Script controls must be registered using RegisterScriptControl() before calling RegisterScriptDescriptors().



Here's some of our code:

'UPDATEPANEL START------------------
Dim upPanel As New Telerik.Web.UI.RadAjaxPanel
Dim sw As New IO.StringWriter()
Dim tw As New HtmlTextWriter(sw)
Dim content As New Literal
upPanel.ID = "upCats"
upPanel.Page = Me.Page
'-----------------------------------

''Filling content here
''Code stripped

'UPDATEPANEL STOP------------------
upPanel.Controls.Add(content)
upPanel.RenderControl(tw) 'ERROR COMES HERE
strCatsOverview &= sw.ToString()
'-----------------------------------

Thx for your quick response!

Hi,

I have found a forum link discussing a similar error.
Script control '...' is not a registered script control.
