How to avoid showing context menu, if the user clicks on empty space on the treeViewAdv?

Platform: WinForms |
Control: TreeViewAdv |
Published Date: April 30, 2011 |
Last Revised Date: July 10, 2014


If the user clicks on the empty space on the treeViewAdv,the appearence of the context menu can be avoided by handling treeViewAdv1_MouseDown and treeViewAdv1_MouseUp Event handler.With the help of this,the user can know which node is being edited currently.Here the Selected node is set to RMouseDownNode.The RMouseDownNode property gets/sets the node on which the user did a right-mousedown


private void treeViewAdv1_MouseDown(object sender, MouseEventArgs e)




if (e.Button == MouseButtons.Right && this.treeViewAdv1.RMouseDownNode.TextBounds.Contains(this.treeViewAdv1.LastMousePositionToClient()))


this.treeViewAdv1.SelectedNode = this.treeViewAdv1.RMouseDownNode;



private void treeViewAdv1_MouseUp(object sender, MouseEventArgs e)





Private Sub treeViewAdv1_MouseDown(ByVal sender As Object, ByVal e As MouseEventArgs)


If Not Me.treeViewAdv1.RMouseDownNode Is Nothing Then

If e.Button = MouseButtons.Right AndAlso Me.treeViewAdv1.RMouseDownNode.TextBounds.Contains(Me.treeViewAdv1.LastMousePositionToClient()) Then

Me.treeViewAdv1.SelectedNode = Me.treeViewAdv1.RMouseDownNode

End If

End If

End Sub

Private Sub treeViewAdv1_MouseUp(ByVal sender As Object, ByVal e As MouseEventArgs)


End Sub
