Hi,

I recently bought telerik control for asp.net Ajax. when i have columns more than 500 and when doing swapping its getting stuck for both ie6 and ie7 browsers. But its working great in Firefox. How to solve this issue? Is there any way to get rid of this? Most of the customers who working on my application are using ie6 or ie7. Please help me.

Thanks

Hi Babu,

Column reordering on the client involves intensive DOM operations and IE is not very good at those in terms of performance. I am afraid you are hitting the browser limits in this case, so please reorder columns on the server only by setting ReorderColumnsOnClient="false" (default value) in the RadGrid's ClientSettings.

Greetings,
