Drag and drop to a panel - Has this been added?

[Bexm]

I have read in the thread below that you were thinking of adding the ability to drag and drop from a treeview to a different control.

I now need to be able to do this, was it ever added?

Thanks

Bex

Hello Bexm,

Thank you for contacting us.

Currently we don't entirely support the OLE drag and drop feature in RadTreeView. However, I have prepared you a simple example, which demonstrates how to get the instance of tree node which is dropped on another control. Please refer to the code block below:

1. Subscribe to the ItemDrag event

       this.radTreeView1.ItemDrag += new Telerik.WinControls.UI.RadTreeView.ItemDragHandler(radTreeView1_ItemDrag);

     2.Get the node instance when the drag operation has started

        RadTreeNode draggedNode;
        void radTreeView1_ItemDrag(object sender, RadTreeViewEventArgs e)
        {
           draggedNode =  e.Node;
        }

      3. Handle the mouseUp handler of RadTreeView and check if the control under the mouse is RadListBox. If the control is RadListBox we add a new ListBoxItem with text equal to the dropped node's one.

void radTreeView1_MouseUp(object sender, MouseEventArgs e)
        {
           if (this.radListBox1.Bounds.Contains(e.Location))
           {
               if (draggedNode != null)
               {
                   RadListBoxItem item = new RadListBoxItem();
                   item.Text = draggedNode.Text;

                   this.radListBox1.Items.Add(item);
               }
           }
        }

I hope this helps. If you need more instructions, please feel free to contact me.
