IE7 performance with RadGrid

[Janise Piombo]

Hi, I'm using RadGrid, to show a list of components. The problem is, when I tried to click on a record, to enter the edit form, the page takes more than 10-15 seconds only to display the editing form. This issue doesn't happen on Chrome or fxf, in those browsers it only takes 3-4 secs to load the page. 

Do you know what I can do to improve the performance on IE??
I already tried disabling pagination, sorting and other features.... I also tried showing only 5 records to see if there's a problem with the qty of data, adding custom pagination to return less results, minimizing Css. 

Is there any known issue with IE? 

I would really appreciate any help you can give me. 

Thanks,
Janise Piombo

Hello Janise,

The reason for the speed difference is quite trivial - the IE Javascript engine is slower.

For various performance hints, please refer to the links below:

Hi

I am experiencing issues with IE7 as well (Firefox & Safari runs fine). I have gone through all the links you keep suggesting to people but have found no useful information. Here's a summary of what I've got:

• RadGrid - all columns are template columns - 2 x RadNumericControls and 1 RadDateTimePicker + DataBoundColumn
• RadCompression enabled
• Using RadAjaxPanel and RadScriptManager
• The page persists the view state in server memory so I cant imagine disabling viewstate will help the problem
• Loading around 70 records.

I think I have done all the things you recommend but still not seeing acceptable performance. Can you please give me any further suggestions - I am using RadControls 2009.2.826.35

Thanks!

Hi Michael,

In order to properly assist you I would suggest you to open a regular support ticket and send us sample runnable example which demonstrates the performance issue. Thus I can check it out and get back to you with a solution.

Thank you.
