I've been following the instructions on this page to get Telerik controls working in a SharePoint WebPart. I'm getting an error on the following line in the OnInit method:
The error says:
"The control collection cannot be modified during DataBind, Init, Load, PreRender or Unload phases."
I reckon the RadScriptManager could be added to the masterpage, but because it is a WebPart we're building we'd much prefer to keep it as a self-contained object. Anyway, it looks like the example code isn't really valid. Am I missing something?
this.Page.Form.Controls.AddAt(0, scriptManager);"The control collection cannot be modified during DataBind, Init, Load, PreRender or Unload phases."

Just tried adding the WebPart again today, and it's working. Not sure why, the code is the same! There were a lot of Windows Updates applied though, I reckon it could be to do with that.
