Is there any ways i can change the effect of the treeviewitem expanding. Default behavior make the child items flow down from top if the parent item is expanded. It hits the performance and feels slower. can it be a normal populating of the child items instead of the effect.

Hello Todd Millett,

You can disable the RadTreeView's animations with the attached property AnimationManager like so:
<telerik:RadTreeView x:Name="tree" telerik:AnimationManager.IsAnimationEnabled="False">
          <telerik:RadTreeViewItem Header="My PC">
              <telerik:RadTreeViewItem Header="Drive A" />
              <telerik:RadTreeViewItem Header="Drive B" />
              <telerik:RadTreeViewItem Header="Drive C" />
              <telerik:RadTreeViewItem Header="Drive D" />
              <telerik:RadTreeViewItem Header="Drive E" />
              <telerik:RadTreeViewItem Header="Drive F" />
              <telerik:RadTreeViewItem Header="Drive G" />
              <telerik:RadTreeViewItem Header="Drive H" />
              <telerik:RadTreeViewItem Header="Drive I" />
          </telerik:RadTreeViewItem>
      </telerik:RadTreeView>
Please let me know if this satisfies you or not and feel free to ask if you need more info.

All the best,
