Hi All,

RAD Grid scrolling(Horizontal and Vertical) performance in IE6 and IE7 is too slow. We need to show more than thousand records with static header but it's working fine in Fire fox and Safari.

Hi Sagar,

I am afraid you are pushing to the limits with those 1000 rows. The static headers functionality involves a lot of DOM operations on the client and IE is considerably slower with these. However, you can do two things to improve the performance:

1. Use ScrollHeight instead of Height for RadGrid.
http://www.telerik.com/help/aspnet-ajax/height-vs-scrollheight.html

2. Use TableLayout="Fixed" for the MasterTableView (which will make all column widths equal) or set all column widths explicitly.

All the best,

Thanks for your quick response Dimo.

The scrolling performance of the grid is very slow even if am displaying 100 records with Scroll height.

1.as you explained we are setting scroll height not grid height.
2.Columns are generated dynamicaly not fixed columns(we need horizontal scrolling here).

can you please suggest ,is there any other approch to overcome this issue.

Regards,
Sagar

Did you get your scrolling issues resolved?
The horozontal scrolling is causing me continous problems.
I have just 10 records per page and the average grid has approx 3 pages.
I have around 30 columns and the scroll from left to right is just dreadfull.
Its slow, jumpy and sometimes it wont even scroll to the end.

I've raised numerous support tickets but I dont really get this resolved.

I'll keep searching the forums ...perhaps Im doing something wrong.

NOTE: The scrolling is better in firefox...although using it in firefox brings other issues.

I really need this to work in IE7 as that the current company standard.

Hello Des,

I do not see any RadGrid scrolling-related tickets in your recent support history. If you provide your current RadGrid setup and elaborate what your problems are, we will test and provide more information.
