Kendoui widgets Randomly failing to render

[DMC Helpdesk]

Hi,

I am using kendoui tabs to load content from different page.One of the pages has a grid widget that gets its data from a WCF data service (json).The grid is randomly failing to render without any errors.

On the same main page, I have 1 pie chart, and a line chart both bound to a WCF data service (json) .They both render when I load the page for the first time. but once i hit F5 or CTRL+F5, they Randomly fail to render.This situation is worse in IE than in Google Chrome and compatibility mode is of no use.

Any ideas on what is happening and how to debug kendoui client scripts ?

Thanks

Hi,

It appears that your case might be in dependency with Json data or widget's configuration and I was not able to reproduce it. It would be best if you could provide a runnable project or page URL that could be examined in details. Please send us such project and we will do our best to detect and solve the problem.

Thank you in advance.

All the best,

Thanks Alexander Valchev.I now can see that my page is working fine in Google Chrome, but not in IE.

My main page (HomePage.html) has three tabs: tab1,tab2,tab3 with content URLs page1.html,page2.html,page3.html


page1.html has a kendoui grid bound to WCF data service.The grid works fine if it is accessed directly from IE9 and chrome

IE9 behavior (Compatibility Mode) When page1.html is loaded in a tab:
The grid in page1.html fails to render if it is loaded in tab1 in HomePage.html, while it renders properly if I move it to tab2. 

Google Chrome behavior When page1.html is loaded in a tab: 
Everything works fine.

Thanks

Hi Madani,

I tried to reproduce the problem, but to no avail. Both Chrome and IE9(Compatibility Mode) rendered correctly the grid and performed the expected Ajax requests. In the attachments you can find the test project that I used. Please check it and let me know if I missed something.
