RadGridView with large data in a TabControl

[James]

I have a Tab control that can show multiple tab items. In one of tab item say tab A, there's a RadGridView which contains large data (> 400 rows). Each time I close another tab say tab B, and leave tab A as the current selected tab, the closing of tab B is very slow which isn't that slow when tab A isn't in the tab strips.

I know RadGridView has UI virtulization by default, I set both EnabledRowVirtulization and EnabledColumnVirtulization to false and this didn't help

any idea?

Hi,

 I've tried this however everything worked pretty fast on my end after the first load. You can check the attached example application for reference. 

Kind regards,
