    i want a msgbox to appear when a node is moved to another. the user should confirm the operation or cancel it.

    i tried to handle it by using the dropped event but i cannot move the moved node back to its origin parent node...

    how can i handle it?

    thanks, andreas

    Try the DragEnding event.  The event arguments have a Cancel property that you can set.

    Hope this helps.

    Hi Аndi,

    You can cancel the operation if you subscribe to the DragEnding, but not to the DragEnded event. Currently, we have an issue with this scenario. When the message box appears, even if you confirm the operation, the node will not be dropped into its new place. This will be addressed for one of our next releases. However, I have made a sample project for you which demonstrates how to workaround this.

    If you need additional assistance, do not hesitate to contact me.
