This is pretty straight forward, in the sample code below it shows how to add a TreeView node with an image into a ListBox. You’ll need an ImageList loaded with images to link both the TreeView and ListBox to and set the ListView to a view that allows images, i.e ‘Tile’.
private TreeNode sourceNode; private void treeView1_ItemDrag(object sender, ItemDragEventArgs e) { sourceNode = (TreeNode)e.Item; if (sourceNode.Parent != null) DoDragDrop(sourceNode, DragDropEffects.Move); } private void DragEnter_Event(object sender, DragEventArgs e) { if (e.Data.GetData(typeof(TreeNode)) != null) e.Effect = DragDropEffects.Move; else e.Effect = DragDropEffects.None; } private void listView1_DragDrop(object sender, DragEventArgs e) { listView.Items.Add(sourceNode.Text, sourceNode.ImageIndex); }
Just add the DragEnter event to the _DragEnter event of the controls you want to allow the DragDropEffects.Move to show on.
