Qui Hi
I would like to select when DragOver a single node, and link code automatically attached selects each node on which the mouse moves
thank you for your help
Here is my code:
e.Effect = DragDropEffects.Move
Dim p As System.Drawing.Point = DiagramView1.PointToClient(New Point(e.X, e.Y))
Dim pt As System.Drawing.PointF = DiagramView1.ClientToDoc(New Point(p.X, p.Y))

If Not TypeOf Diagram1.GetItemAt(DiagramView1.ClientToDoc(p), False) Is DiagramItem Then
Exit Sub
End If

Dim item As DiagramItem = Diagram1.GetItemAt(DiagramView1.ClientToDoc(p), False)
If Not item Is Nothing Then

'Debug.WriteLine(item.Tag.ToString & "<>" & ItemOld)
If item.Tag.ToString <> ItemOld.ToString Then
Debug.WriteLine(item.Tag.ToString & "<>" & ItemOld.ToString)
'ItemOld.Selected = False
item.Selected = True


ItemOld = CType(item.Tag, Guid)
End If
End If
