Testing Workflow

[ITA]

Hi,

we are using RadDiagram as a WorkflowDesigner for a business-software. How can we test different processes, whether they are produced correctly? Is there a Startpoint (Shape), are the Connectors ok, ...? Any ideas how so solve this?

Thanks

Hi Rene,
Unfortunately the RadDiagram doesn't have a built-in workflow validator so you'll have to do this manually. There are different ways to validate your diagram and it all depends on your custom scenario - are you using MVVM, custom shapes, custom connectors and etc.
By design the diagram control is highly customizable and you can change a lot of its default behaviors - I've attached a sample project that has a runtime connection validation - you can start a connection only from a right connector and you can end it only in a left connector, also each connector can have only one connection.
I hope I was able to help you and if you have more questions feel free to ask.

Hi,

one more question. I use a custom Shape (Geometry = ShapeFactory.GetShapeGeometry(FlowChartShapeType.DecisionShape))
How can I examine how many connectors are incoming and how many are outgoing? Here is just one incoming connector allowed?

Thanks

Hi Rene,
You can iterate through the Connectors collection of the RadDiagramShape and check what the connectors are with something like this:

foreach (var connector in shape.Connectors)
{
    var inOutCon = connector as InOutConnector;
    if (inOutCon != null)
    {
        // InOutConnector.
        var direction = inOutCon.Direction;
    }
    else
    {
        // normal connector.
    }
}

I hope I was able to help you.
