I have created an array of Nshapes, and I need to know when a Shape is selected with the right or the left mouse button. I have added this:

AddHandler DrawingView.EventSinkService.NodeSelected, AddressOf EventSinkServiceNodeSelected

This works but ONLY with the LEFT button. When I press the right button in a shape, that event is not fired.

I tried with this another:

AddHandler DrawingView.EventSinkService.NodeMouseDown, AddressOf EventSinkServiceNodeMouseDown

But it doesn't work AT ALL. I was seeing this page :

But I don't find the solution. Does anybody can help me ?

I've got it . First I had to add a handler for the drawingview:

AddHandler DrawingView.MouseDown, AddressOf DrawingView_MouseDown

And this is the code for de sub

Private Sub DrawingView_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles DrawingView.MouseDown

Dim ActiveShape As Object = DrawingView.LastActiveDocumentContentHit(DrawingView.GetMousePositionInDevice(), -1, Nevron.Diagram.Filters.NFilters.TypeNShape)

Dim XShape As NShape = CType(ActiveShape, NShape)

If e.Button = Windows.Forms.MouseButtons.Right And Not XShape Is Nothing Then

ContextMenuStripTree.Show(DrawingView, CInt(e.X), CInt(e.Y))

End If

End Sub
