Update Panel not working properly

[ankur]

I am using DNN(DotNetNutke) 07.01.00 (2676) for website. DNN internally uses Telerik Controls.

I am using asp.net Update Panel in my page, so there is a Button inside that UpdatePanel (named as "UPDATE CART" in screen shot of page) and when i click on this button request goes to server and executes the code on server and then response comes with rendered HTML and update the content of UpdatePanel.




So problem here is like that when i click this button("UPDATE CART") first time(i.e.when i come to this page first time or say it is not post back or IsPostback ==false) then my content of Update Panel just get updated but after that if i click the button again(IsPostBack==true) then content of Update Panel does not change although the request always goes to server every time and also response is sent from server without any error but content of Update Panel doesn't change.

So i checked client side code in chrome's developer tool then i got to know that some javascript/jquery exception(refer to Screen Shot) is coming whenever this Page loads.But exception details differs when the page loaded first time(i.e. IsPostback == false) and when it is posted back(i.e. IsPostBack == true).

Here is the screen shot of exception


Here is the screen shot of exception detail when page loaded first time.


Here is the screen shot of exception detail when Page's IsPostBack== true or i clicked that "UPDATE CART".button again and again(not the first time).


But interesting thing what i noticed is that when i logged-in as a DNN Super User in website and come to this page then no exception comes and functionality works well or content of Update Panel always change on "UPDATE CART" button clicks but whenever i logged-in as other user i.e. rather then DNN Super User i i always face this problem.

So please help me asap and sorry for my bad English.

Hi Pavlina,

I also posted this same issue on dnn forum but i didnt get the sufficient solution.
So i thought to post here on telerik forum , in a hope that may be i will get solution from here.

Hello,

To identify whether the problem is DNN-related or not, you can check whether moving the Telerik controls outside of the DotNetNuke environment makes a difference. If the described problem still persists we will do everything possible to provide more definite answer.
