I\'m trying to do something that many people seem to have been able to do but which I am unable to implement any solution. The TinyMCE control works pretty well in an asp.net fo
The correct way to make tinyMCE work in an updatepanel:
1) Create a handler for the OnClientClick of your "submit" button.
2) Run tinyMCE.execCommand("mceRemoveControl", false, '<%= txtMCE.ClientID %>'); in the handler, so as to remove the tinyMCE instance before the postback.
3) In your async postback, use the ScriptManager.RegisterStartupScript to run tinyMCE.execCommand("mceAddControl", true, '<%= txtMCE.ClientID %>');
Basically, all you need to do is use the mceRemoveControl command before the async postback and register a startup script to run the mceAddControl command after the async postback. Not too tough.
