Hi,

The RadGridView Control is taking a long time to render.

I followed exactly ALL of the recommendations listed here :
https://docs.telerik.com/devtools/wpf/controls/radgridview/performance/tips-tricks

10 Rows
5 Columns
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 ?

Regards.

Hi Julien,

Thank you for the provided details and images.

This behavior is unexpected, as you have minimal data shown in the RadGridView. To have a better look, is it possible to isolate this behavior in a standalone project. This way, I can also debug it on my side and get to the bottom of this.

I am looking forward to your reply.

Regards,
