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

I'm using 9.5.11.12 and visual basic 2005 Team Edition

Weird, it works for me, although I'm using C#.  I'm using 13.1.7.12 version of Nevron.Diagrams.  What version are you using?

I tried this event handler but I get the same as the other event handler (NodeMouseDown)

I was able to get it working using this event handler:

NDrawingDocument.EventSinkService.NodeMouseUp

It has a Button property on the args that tells you which button was pressed on the mouse.

Hope that helps,

What I want is when the user press the right button on a shape, a context menu has to be opened.

Hi Luis,

Please elaborate what you are trying to achieve? Do you want shape to be selected by clicking on a shape with either the left or the right mouse button, or do you simply want to be notified when a shape is clicked with the left or the right mouse button?

Best Regards,

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 ?
