Hi. i would like to further add that,

this error only occur on the user end, if i access the same page directly from the server the JS error won't occur.

Further i deploy this same piece on a different server. the JS error did not happen when i tried to access the page on server side or client.

 

 

i

f there is issue with the code behind won't the error occur no matter where i access the page?

but for my case, this error only occur on the user end, if i access the same page directly from the server the JS error won't occur.

i have isolated the error to be happening somewhere when the repeater is rendering the new set of control.

if i replace RadEditor with asp:Textbox. this error will not happen.

removing the background colour and font colour tools seems to fix the issue. but i need this 2 tool.. need help on this how to fix this error?
