Permissive shape connections

[Robert]

Hi,

I want to restrict which shapes can be connected. In my application there are rules of which shapes may be connected. What I want is that if a user tries to connect two shapes, that cannot be connected (incompatible?) it will reject the connection or display an error on the connection.

Can I do this?

Thx

Rob

Hello Rob,

To cancel connections you can use the ConnectionManipulationCompleted and ConnectionManipulationStarted of the RadDiagram control. To do so, handle the event. For example:

private void RadDiagram_ConnectionManipulationCompleted(object sender, Telerik.Windows.Controls.Diagrams.ManipulationRoutedEventArgs e)
        {
            e.Handled = true;
        }

The ConnectionManipulationCompleted will cancel the attachment of a connection. And the ConnectionManipulationStarted will cancel the drag start.

I hope this helps.

That looks like exactly what I needed.
