Hi. I have managed to work out how to get the node's index during drag and drop but how do I change the following code to get the node's name

    Private Sub TreeView_From_ItemDrag(sender As Object, e As System.Windows.Forms.ItemDragEventArgs) Handles TreeView_From.ItemDrag
        'Set the drag node and initiate the DragDrop
        DoDragDrop(e.Item, DragDropEffects.Copy)
        MsgBox(e.Item(e.Item.Index).name)

    End Sub

Have you tried

MsgBox(e.Item.name)

?

Hi. That returns the word "Column" for every node. The nodes are loaded with SQL table columns. Not sure if this has something to do with it

>Childnode = Mainnode.Nodes.Add(key:="Column"

It appears that key is being used for name.

Try changing it to

Childnode = Mainnode.Nodes.Add(row(1).ToString)
