Drag files from Windows Explorer to Treeview

[TheWizardofInt]

I am trying to drag files from subdirectories in Windows Explorer to Treeview

 

No matter how I code the thing, it says that the drag as no data, and therefore doesn't populate

 

What am I doing wrong here?

 

Private Sub TreeView1_DragDrop(ByVal sender As Object, ByVal e As System.Windows.Forms.DragEventArgs) Handles TreeView1.DragDrop
       Dim oNode As New System.Windows.Forms.TreeNode

       If e.Data.GetDataPresent("System.Windows.Forms.TreeNode", False) Then
           Try
               For Each oNode In TreeView1.Nodes
                   oNode.Remove()
               Next
               oNode.ImageIndex = 0    ' Closed folder 
               oNode.SelectedImageIndex = 0
               oNode.Text = e.Data.GetData(DataFormats.Text).ToString()
               'oNode.Text = e.Data.GetData("System.Windows.Forms.TreeNode")
               TreeView1.Nodes.Add(oNode)
               oNode.Nodes.Add("")
               'TreeView1.Nodes.Add(oNode)
           Catch ex As Exception
               MsgBox("Cannot create initial node:" & ex.ToString)
               End
           End Try
       End If
   End Sub

   Private Sub TreeView1_DragEnter(ByVal sender As Object, ByVal e As System.Windows.Forms.DragEventArgs) Handles TreeView1.DragEnter
       e.Effect = DragDropEffects.Copy
       ' If the data is text, copy the data tao the RichTextBox control.
       If e.Data.GetDataPresent(DataFormats.Text) Then
           e.Effect = DragDropEffects.Copy
       Else
           e.Effect = DragDropEffects.None
       End If
   End Sub

   Private Sub TreeView1_ItemDrag(ByVal sender As Object, ByVal e As System.Windows.Forms.ItemDragEventArgs) Handles TreeView1.ItemDrag
       DoDragDrop(e.Item, DragDropEffects.Copy)
   End Sub

try FileDrop instead of expecting windows explorer to send you tree nodes.

this happened to me before as well.

Actually there is a workaround availlable in MSDN. But I forgot where already..

 

Anyway, I had found out a c-sharp version of the workaround from Google. Feel free to have a look on here
