Hello,
I would like to know how can I make the the drop preview line be vertical.
I used ItemsPanel to make the tree items be horizontal, but when I set the "IsDragDropEnabled" property true, I found that the drop preview line is horizontal, as you know, it should be vertical. What I need to do?
<telerik:RadTreeView.ItemsPanel> <ItemsPanelTemplate> <StackPanel Orientation="Horizontal" HorizontalAlignment="Center"></StackPanel> </ItemsPanelTemplate>
