How can I detect the right click on a node ?

 

The right click on a node can be detected using the 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
