It seems that I've misunderstood the issue. If I drag the vertical scrollbar I also cannot scroll properly. This happens because when you allow dragging the DragDropManager is subscribing the control for some drag events that interfere with the dragging of the scrollbar. You can resolve this by using the AllowDrag property, instead of AllowCapturedDrag, as you already found.
Also, can you tell me why do you need to set the AllowDrag property on the RadTreeListView itself? Usually, the property is set on the child elements of the control to allow them to be dragable. Which means that setting the property to True for a specific element tells the DragDropManager that its events can be fired for this specific element. If you want to drag/drop rows, you can set the AllowDrag on the TreeListViewRow elements via the RowStyle
And then implement a custom drag/drop functionality using DragDropManager
, as shown in the "Drag and Drop" demo
I hope this helps.
