Sorry for the introduced inconvenience.
I logged the issue in our Public Issue Tracking System. We will provide a way to achieve the desired behavior in Q2 2011 due in the middle of July. We will update the documentation accordingly. Currently, you can use the following code snippet:
void radTreeView1_DragOverNode(object sender, RadTreeViewDragCancelEventArgs e)
if (e.TargetNode == null)
TreeNodeElement nodeElement = e.TreeElement.GetElement(e.TargetNode);
if (nodeElement == null || nodeElement.ItemHeight <= 0)
double height = nodeElement.ItemHeight;
double zone = this.radTreeView1.TreeViewElement.DragDropService.DropLocation.Y;
if (zone <= height / 3)
else if (zone >= height - (height / 3) )
As to the Source Code, if I understand your description correctly, you are getting an old version of the source code while trying to access a link that claims to point to the latest version of the code. However, I was not able to reproduce the described behavior. When I navigate to the link pointed out in the attached screenshot, the Source Code that I download is correct. Could you please check the AssemblyInfo file of the TelerikCommon project? If its Telerik.WinControls.VersionNumber.Number is 2011.1.11.0419, this means that you have downloaded the correct Source Code.
All the best,
the Telerik team
