Hi,

We are evaluating Nevron Diagramming for Winform for our current project. We have found it very useful till now.

We have a requirement where we need to have outward ports. But we noticed that we are not able to connect the outward ports. Please let us know if this is an issue or if there is a specific way to do it.

We greatly appreciate your support. Thanks in advance.

Regards,

Ravali Allam

One of the Nevron Support team gave me some code about using my Line connector to connect two shapes (one explicitly set as PortType.Inward, shape.Name="PPMDOut")
and other shape with default Type (shape.Name = "PPMDIn").

A Connecting event handler was created.
nDrawingDocument1.EventSinkService.Connecting += new ConnectionCancelEventHandler(EventSinkService_Connecting);

///

/// This event occurs when 2 shapes arre connecting on the drawing veiw. Here is the place where you
/// can cancel the connection if you want.
///

///
private void EventSinkService_Connecting(NConnectionCancelEventArgs args)
{
NPlug plug = (NPlug)args.Document.GetDescendantFromUniqueId(args.UniqueId1, -1);
NPort port = (NPort)args.Document.GetDescendantFromUniqueId(args.UniqueId2, -1);

if (plug is NStartPlug)
{
// This is a start plug
if (port.Shape.Name == "PPMDOut")
{
// Start plug connection not allowed for Digital Output shapes - show a wanring
// message and cancel the connection
MessageBox.Show("Connecting Start Plugs to a 'Digital Output' shape is not allowed!",
"Warning", MessageBoxButtons.OK, MessageBoxIcon.Warning);
args.Cancel = true;
}
}
else
{
// This is an end plug
if (port.Shape.Name == "PPMDIn")
{
// End plug connections not allowed for Digital Input shapes - show a warning
// message and cancel the connection
MessageBox.Show("Connecting End Plugs to a 'Digital Input' shape is not allowed!",
"Warning", MessageBoxButtons.OK, MessageBoxIcon.Warning);
args.Cancel = true;
}
}
}
