The following code snippet demonstrates how you can clone or copy all the nodes in TreeView1 to TreeView2 by clicking on Button1. ’ Convert from Screen coordinates to Form coordinatesĭim FormPoint As Point = Me.PointToClient(ScreenPoint) ’ Convert from Tree coordinates to Screen coordinatesĭim ScreenPoint As Point = treeView1.PointToScreen(ClickPoint) Private Sub treeView1_MouseUp(ByVal sender As Object, ByVal e As )ĭim ClickPoint As Point = New Point(e.X,e.Y)ĭim ClickNode As TreeNode = treeView1.GetNodeAt(ClickPoint) Point FormPoint = this.PointToClient(ScreenPoint) Convert from Screen coordinates to Form coordinates Point ScreenPoint = treeView1.PointToScreen(ClickPoint) Convert from Tree coordinates to Screen coordinates TreeNode ClickNode = treeView1.GetNodeAt(ClickPoint) Private void treeView1_MouseUp(object sender, e) You can display a context menu when a user right-clicks on a node by listening to the TreeView’s MouseUp event as shown below: Private void treeView2_ItemDrag(object sender, e)ĭoDragDrop(e.Item, DragDropEffects.Move) Private void treeView2_DragEnter(object sender, e) (newNode.Clone()) ĭ((TreeNode) newNode.Clone()) NewNode = (TreeNode) e.Data.GetData('''') Pt = treeView2.PointToClient(new Point(e.X, e.Y)) ĭestinationNode = treeView2.GetNodeAt(pt) private void treeView2_DragDrop(object sender, e) You can get C# code in this sample, TreeViewDnD. In a posting in the newsgroup, Brian Roder (Microsoft) gives VB.Net code snippets to handle the DragEnter, ItemDrag and DragDrop events that provide a solution to this problem.
