Hi
I have resolved this by adding 2 hidden fileds that cute editor creates.
<input type='hidden' name='ctl00$ContentPlaceHolder1$tbFolder$TabPreviewTest$Editor1$ClientState'
value='' />
<input type='hidden' name='ctl00$ContentPlaceHolder1$tbFolder$TabPreviewTest$Editor1$PostBackHandler' />
I guess the issue was because of the load time taken by cute editor.
But adding these 2 hidden fields, the issue is resolved.
Thanks and Regards
