difficult to override RenderControl() methord with Telerik

[wajira]

I need to dynamically add some controlls to a web user control.
  
I'm putting all the controlls to a Table control and adding to the page as follows at the RenderControl event.

 

Public Overrides Sub RenderControl(ByVal writer As System.Web.UI.HtmlTextWriter)

 

 

Dim panel As New Panel

 

 

Dim outerTable As New Table

 

outerTable = generateDynamicControls()

panel.Controls.Add(outerTable)

panel.RenderControl(writer)

 

MyBase.RenderControl(writer)

 

 

End Sub

 

When I adding simple ASP controls to this outer table, it is working fine.
But when I add Telerik Controls gives following error when it execute  "panel.RenderControl(writer)" code.
Error:
Page cannot be null. Please ensure that this operation is being performed in the context of an ASP.NET request.

I'm using a Master page also.

Can u help me?

Did you ever get an answer for this?

Hello guys,

Adding ASP.NET server controls on the RenderControl phase is too late in the control lifecycle, thus their viewstate will be corrupted and they will behave abnormality. You should generate those controls either When the Init/Load or the CreateChildControls event of the user control is raised.
