Hello,

       I have a problem with performance in rad window. I open a page in rad window which contains splitter control and inside this splitter control i have two panes. In one pane i have rad multiview control which has three pageviews. and in another pane i have user controls.
in one of my pageview i have radGrid when i populate records in radgrid on clicking of button. its gives me performance and also when i am doing refresh of usercontrol and also populating radgrid on button click. Can you help how to overcome the performance issues. This is very urgently required. Very Very Urgent as it deals with doing more operations on this radwindow. I can't find why performance is effected so much badly. it takes early 2 mins to complete the process. Required help very urgently.

Thanks & Regards,

R. Vikram Goud

Hi vikram,
From the provided information, I am not quite sure that the problem you have is caused by the RadWindow control. Could you please open the page with the RadSplitter in a standard browser window and see if this will improve the performance? In case you page behaves as expected without our RadWindow control, please open a new support ticket and send us a simple running project, demonstrating the problem, so that we can research on our end what is causing it.

In case the performance of your page does not improve by switching the RadWindow with the browser window, the problem is actually in the page you open in the RadWindow, rather than in the RadWindow itself. As far as I understand you, you get the bad performance only when you populate your RadGrid with data - please correct me if I am wrong. If this is correct, how may records do you display? I would recommend that you ajaxify the controls in your page and load only the data that you really need to display - e.g. use the paging functionality of the RadGrid to display a small set of records in the RadGrid at a time.

Sincerely yours,

Hello Tsvetie,
