Window workflow foundation 4.0 (WPF): How to change an activity location in a Flowchart workflow by code

Question

I use rehosting workflow designer ( https://msdn.microsoft.com/en-us/library/dd489419%28v=vs.100%29.aspx ) to load a Flowchart workflow in my application.

 Flowchart flowchart = this.CreateFlowchart();///Create a Flowchart workflow
 WorkflowDesigner wd = new WorkflowDesigner();
 wd.Load(flowchart);

How should I do to change an activity location in the Flowchart?

Answer 1

This is certainly not a trivial task.

You effectively need to alter the location of the model item via the view state service.

wd.Context.Services.GetService<ViewStateService>().StoreViewStateWithUndo(modelItem, "ShapeLocation", new Point(20,20));

Have a read of this article which explains view state far better than I can.
