    In my treeview control i have a root directory and is there anyway to prevent a child node in the root from being drapped outside the root node.

    This is answered in the documentation.

    TreeView --> Events --> Drag event

    I hope this helps.

    This doesn't show how to prevent from dropping on the TOP Root Node. So for example, 

    Root

         Child

          Child

     

    NEW but Not wanted Tree structure:

    Root

        CHILD

        CHILD 

    CHILD

    Hello,

    Please check this example which demonstrates the scenario. In general you can use the treeview drag and drop events to restrict the treeview drag and drop behavior.

    Thanks Daniel. I think the code you gave is what is needed because I couldn't determine what was a root node but your example shows it. Thank you.
