Thank you for writing.
I would recommend you to have a look at the TreeView >> Drag and Drop in bound mode
help article which is quite useful on this topic. RadTreeView
to perform the drag and drop operation. The PreviewDragOver
event allows you to control on what target the node being dragged can be dropped on. The RadDragOverEventArgs.HitTarget
property gives you access to the target TreeNodeElement
from which you can get the RadTreeNode
and its parent to check the DataBoundItem
. Thus, you can construct the condition for the drop operation.
I hope this information helps. Should you have further questions, I would be glad to help.
Do you want to have your say when we set our development plans?
Do you want to know when a feature you care about is added or when a bug fixed?
