How to perform the node drag drop between a WinForms XPToolBar and TreeViewAdv?

Platform: WinForms |
Control: XPToolbar |
Published Date: April 30, 2011 |

Perform the node drag drop between XPToolBar and TreeViewAdv

Please refer the following steps to be performed to achieve this:

1. Place the TreeViewAdv and XPToolBar on the form.

2. Add nodes to the TreeViewAdv.

3. Set the AllowDrop property as True of the XPToolBar.

4. Handle the TreeViewAdv MouseDown event to access the node which is going to drag.

5. Handle the DragDrop and DragEnter events of XPToolBar to get the which is dragged from the TreeViewAdv.

Please refer the below code snippet which ilustrates this:

C#

private void xpToolBar1_DragEnter(object sender, System.Windows.Forms.DragEventArgs e)
{
   Console.WriteLine("XPToolBar Drag Enter");
   if (e.Data.GetDataPresent(typeof(TreeNodeAdv)))
      e.Effect = DragDropEffects.Copy;
   else
      e.Effect = DragDropEffects.None;
}
private void xpToolBar1_DragDrop(object sender, System.Windows.Forms.DragEventArgs e)
{
   Console.WriteLine("XPToolBar Drag Drop");
   if (e.Data.GetDataPresent(typeof(TreeNodeAdv)))
   {
      TreeNodeAdv node = e.Data.GetData(typeof(TreeNodeAdv)) as TreeNodeAdv;
      BarItem bitem = new BarItem(node.Text);
      this.xpToolBar1.Items.Add(bitem);
   }
}
private void treeViewAdv1_MouseDown(object sender, System.Windows.Forms.MouseEventArgs e)
{
   if (e.Button == MouseButtons.Left)
   {
       // get the point where the mouse was left clicked
       Point p = this.treeViewAdv1.PointToClient(Control.MousePosition);
       // get the node at the left click point
       TreeNodeAdv node = this.treeViewAdv1.PointToNode(p);
       this.treeViewAdv1.SelectedNode = node;
       this.treeViewAdv1.Refresh();
       DoDragDrop(node, DragDropEffects.Copy);
   }
}

VB

Private Sub XpToolBar1_DragDrop(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DragEventArgs) Handles XpToolBar1.DragDrop
   Console.WriteLine("XPToolBar Drag Drop")
   If e.Data.GetDataPresent(GetType(TreeNodeAdv)) Then
       Dim node As TreeNodeAdv = CType(IIf(TypeOf e.Data.GetData(GetType(TreeNodeAdv)) Is TreeNodeAdv, e.Data.GetData(GetType(TreeNodeAdv)), Nothing), TreeNodeAdv)
       Dim bitem As BarItem = New BarItem(node.Text)
       Me.XpToolBar1.Items.Add(bitem)
   End If
End Sub
Private Sub XpToolBar1_DragEnter(ByVal sender As System.Object, ByVal e As System.Windows.Forms.DragEventArgs) Handles XpToolBar1.DragEnter
   Console.WriteLine("XPToolBar Drag Enter")
   If e.Data.GetDataPresent(GetType(TreeNodeAdv)) Then
       e.Effect = DragDropEffects.Copy
   Else
       e.Effect = DragDropEffects.None
   End If
End Sub
Private Sub TreeViewAdv1_MouseDown(ByVal sender As System.Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles TreeViewAdv1.MouseDown
   If e.Button = Windows.Forms.MouseButtons.Left Then
       ' get the point where the mouse was left clicked
       Dim p As Point = Me.TreeViewAdv1.PointToClient(Control.MousePosition)
       ' get the node at the left click point
       Dim node As TreeNodeAdv = Me.TreeViewAdv1.PointToNode(p)
       Me.TreeViewAdv1.SelectedNode = node
       Me.TreeViewAdv1.Refresh()
       DoDragDrop(node, DragDropEffects.Copy)
   End If
End Sub
