Error:- Tree view : Sys.UI.DomEvent.addHandler method, for Licensed version 2010.3.1215.40

[Sundararaman]

Hello Telerik Team,

Its urgent... Today We have installed the Latest Telerik Licensed version No: 2010.3.1215.40.
But we have got the below error when click on Tree view OR Multipe TABS.

Problem is as Follows:
1) Click on any Tree view Node OR on Multiple Tabs, the Ajax control keeps on Loading and generates below javascript error:
 
"Sys.InvalidOperationException: Handler was not added through the Sys.UI.DomEvent.addHandler method."

Previously this was working correctly at all places with the version  2010.2.929.40

Let us know the possible solution for the same ASAP.

Regards
Sudhakar

Hello Pavel,

Thankyou for prompt response.
The solution provided works only for first time and subsequent clicks on Tree view or Tabs is still  displaying  the same problem.

"Sys.InvalidOperationException: Handler was not added through the Sys.UI.DomEvent.addHandler method."

Are you suggesting to install the hotfix as well..?

Hi Sudhakar,

Indeed you can try the hotfix. The only reason I can think of for the workaround to work only once is that the script is not added to the correct page or pages.

Kind regards,

Hello Pavel,

Subsequent clicks are on the same one page, but still cannot.

Anyways it is fixed now, after installing the Hot fix patch.
Thankyou for the same.
