How can I detect the right click on a node?
The right click on a node can be detected using the WinForms Diagram MouseUp event as shown in the following code snippet,
C#
private void diagram1_MouseUp(object sender, System.Windows.Forms.MouseEventArgs e)
{
if (e.Button == MouseButtons.Right && this.diagram1.Controller.NodesHit.Count > 0 && this.diagram1.View.SelectionList.Count != 0)
{
if (this.diagram1.View.SelectionList.First is FilledPath)
{
this.contextMenu1.Show(this.diagram1, new Point(e.X, e.Y));
}
}
}
VB
Private Sub diagram1_MouseUp(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles diagram1.MouseUp
If e.Button = Windows.Forms.MouseButtons.Right AndAlso Me.diagram1.Controller.NodesHit.Count > 0 AndAlso Me.diagram1.View.SelectionList.Count <> 0 Then
If TypeOf Me.diagram1.View.SelectionList.First Is FilledPath Then
Me.contextMenu1.Show(Me.diagram1, New Point(e.X, e.Y))
End If
End If
End Sub
