The RadGridView Control is taking a long time to render.
I followed exactly ALL of the recommendations listed here :
Binding only preloaded string (no code exucution delay)
But still, there is a noticable delay.
Loading an UserControl with a RadGridView in it from a TabControl for example freezes the ui for quite some time.
It will be really noticiable for the enduser.
It takes more than 3 times the loading time of a Microsoft DataGrid (see attachements), why ?
