Radgrid pageing problem

[Jeff Tang]

I have a datatable that have 500 rows. And I assign it to the Radgrid by
"rgAdvSearch.DataSource = dtData" at page_load. My Radgrid don't have paging, but it takes over a minutes to finish loading. When I enable the paging of the Radgrid, it take only few seconds to get it done. I want to know how can it be faster if I don't want paging. Thanks.

Hi Jeff,

Here is a help article which explains on optimizing the Grid performance. Go through it and see if it helps.

The problem is that when I use the change page size function to change the page size to the total number of records, it turns out the performance is ok. But it is so slow if I initially set a large page size. I don't know why.
