I am getting the following error on my page.

Script control 'WebTextEditor1' is not a registered script control. Script controls must be registered using RegisterScriptControl() before calling RegisterScriptDescriptors().
Parameter name: scriptControl

What I did was to copy the code from a .aspx page that is working to a different page.. I needed the same grid and everything so I just copied it. I know, that was probably the mistake...

I have gone as far as to remove the WebTextEditior, My WebScriptManager, and several other things and replaced them with new objects using the normal drag and drop but as soon as I put a WebTextEditior in, Same error.

Any ideas?
