I installed the RadEditor some time ago and have sporadically recieved the error. "The control collection cannot be modified during DataBind, Init, Load, PreRender or Unload phases." Ever since. We finally got it to reproduce with the repository module in DNN. If  after installing RadEditor as your default editor you go into Settings on the repository and then click update the error appears.
While Debugging we tracked it to line 509 of the Telerik RadEditor provider it's inside the RadEditor_Load Event Handler.
The Code reads
--------------------------------------------------------------------------
_editor.Parent.Controls.Add(New LiteralControl(String.Format("<link title='Telerik stylesheet' type='text/css' rel='stylesheet' href='{0}'></link>", editorPage.Server.HtmlEncode(cssOverrideUrl))))
Else IF
-------------------------------------------------------
Looks like in some instances the Provider is attempting to add the Control to the collection at an invalid time runing the postback. To fix it for now we changed our provider to read

Try
_editor.Parent.Controls.Add(New LiteralControl(String.Format("<link title='Telerik stylesheet' type='text/css' rel='stylesheet' href='{0}'></link>", editorPage.Server.HtmlEncode(cssOverrideUrl))))
Catch ex As HttpException
    'The control collection cannot be modified during DataBind, Init, Load, PreRender or Unload phases.
End Try

Any official Word on this? 
Anyone else noticing this?

Any word on this? Is this a sanctioned fix for a Documented Bug or just something unique to me?

Hi David,

This is a confirmed bug with the editor in DNN and some Ajax scenarios. Could you please, download the latest DNN modules build Telerik.DNN.Modules_2008_2_723_dev.zip from the My Licenses -> My Purchases section under your Client.net account and see whether the problem still persists.

Best regards,

David,

I actually can't find where you made this code change. I'd love to implement the Telerik editor but I can't get past this error. If you could give me a little more direction from your code example.

Currently I installed the Telerik DNN module and enabled it. I've hunted through the regular source as well as the source files provided from the DNN module but can't find your code example anywhere.

Thank you

Ah HA!

Nevermind. I found it. Having used the module to install the telerik editor I didn't see where all the files were going.

Having found this page:
http://dnn.telerik.com/Support/radEditorHtmlproviderinstallation/tabid/49/Default.aspx

Explained where the file i was missing was... App_Code/RadEditorProvider.vb
