I have an issue with multiselection with WPF RadGridView. I set MultipleSelect="True". It allows to select multiple rows, but when I MouseDown to one of selected rows (in order to drag them), other rows become disselected. I want the multiselect to act same way as a "my computer" (select mutiple items, mouse down on one of selected items and drag them). Is it something that we can do with RadGridView?
