I have a RadGridView (SelectionMode.Extended) with ItemsSource of type VirtualQueryableCollectionView. Source is a database wich is connected via EntityFramework.
When I select the first row in the GridView and go down to the bottom and select the last row (or any other), all items in between are fetched from the databse, although I didn't pressed SHIFT. This needs very much time I have many data.
Is there any reason, why the table thinks it has to load all rows between the first an the second selection? Is there any way, to change this behaviour?
I think, this should only happen, if I SHIFT+Click on a row.
