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 ?

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?

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

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,
Charley

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

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'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
