Telerik Support,

Do you have any online demos of grids containing over 100 rows of data?
I'm finding the performance of this control painstakingly slow when there are several records and want to compare to your code to see if it's something I'm doing or a shortcoming of your controls.

Cheers

I should also add that when there's a reasonably large grid on the page (ordinarily I don't consider 100 rows large, but RadGrid seems to struggle at this size) then all other Telerik controls' performance degrades too.

Is there a way to disable all client-side events that we aren't interested in? I'm guessing that memory is being consumed by events that aren't even needed.

Cheers

Hi Daron,

We made some significant data-binding performance optimizations for the latest versions of RadGrid Prometheus/RadGrid Classic and now the control refreshes up to ten times faster:

Below are several links to online demos in which the grid table consists of several hundred/thousand records:

Additional hints about how to optimize the performance of the control you can find under the Controls -> RadGrid -> Performance tips and tricks chapter from the online help:
