RadGrid Editmode Performance

[Harry]

When I try to use the RadGrid buildin edit form , I found when I click the 'Add new record' or 'Edit' ,that will cause the full grid be re-flash . If the web site is in local network ,the performance seems ok.  But if access the web site from internet and the grid records number is very big. The performance will be very low. User will take a long time to wait the edit form appear.
Please see the grid online demo "Grid / PopUp Edit Form" page. That is a very well sample to point this issue.
http://demos.telerik.com/aspnet-ajax/grid/examples/dataediting/popupeditform/defaultcs.aspx

In this sample, there're two grid on this page. One is more records, another is less. When I click the 'Add new record' command item,  the performance will be very obvious differences. The first grid will take 4 sec. to show the edit form but the second grid just take 1 sec. . I think if the first grid has more and more records that will take more and more times to show the edit form.


So how to improve the performance when use build-in edit form.

Hi Harry,

It is expected when present large number of records at once to see delays in the grid operations execution. However, for useful tips on how to optimize your grid performance you can review the online resources below:

I hope this helps.
