Am trying to do the simplest of things in winforms/vb using the RadDiagram ..

Below is my simple test code -

Dim acon As New RadDiagramConnection
acon.StartPoint = New Point(10, 100)
acon.EndPoint = New Point(50, 750)
acon.Name = "Line"

AddHandler acon.Click, AddressOf mme

Private Sub mme()
  MsgBox("LNE")
End Sub
