I'm trying to bind RadGridView SelectedItems property to a property on my ViewModel using the custom Behavior approach mentioned in the Vladimir Enchev's blog post and it works fine.
However, when gridview contains several thousands items and I try to select them all, the time necessary to select all items is tens of seconds, sometimes even minutes. This is not unacceptable by ours customers.
Can you help me solve this problem?
Thanks

PS: I've prepared sample project to show this behavior but there is no way to post it.
