Line connector issues

I am using version 6.2 of the Diagram control in VB (Windows Forms version).

I am having some issues with the line connectors between two rectangles. When I create an ortogonal connector, it joins the two central points as expected, with the line beginning at the rectangle's edge.

However, if I begin moving (dragging) one of the rectangles around the model, the line connector tends to get redrawn incorrectly and will originate from the actual central point (and obscuring text within the rectangle), rather than beginning at the rectangle's edge.

I've attached a sample image so you can see the behaviour I am experiencing.

Is this a bug, or do I need to code some workaround or set some property in order to fix the problem?

Thank you

Hi Mark ,

You can resolve this issue by sending the connector to back of the connected nodes. Please use the below code snippet.

OrthogonalConnector line = new OrthogonalConnector(m_rect.PinPoint, m_rect1.PinPoint);
this.diagram1.Model.AppendChild(line);
m_rect.CentralPort.TryConnect(line.HeadEndPoint);
m_rect1.CentralPort.TryConnect(line.TailEndPoint);
this.diagram1.Model.SendToBack(line);

Please refer to the attached sample for more details.

Let me know if this helps.

Thanks for the sample code. It does work better for me now.

However, I can still reproduce one case where the connector is not drawn properly, as it becomes obscured by the rectangle.

I've attached another screen shot with a sample of what I'm seeing.

Can this be considered a bug? Or is there another property I need to set on the orthogonal connector to make it connect properly?

Thanks so much.
