Detecting changes to a workflow in rehosted designer.

Question

Is it possible to check to see if any changes were made to a workflow in the rehosted designer? I'd like to prompt the user to save their changes if they are trying to close or load a different workflow and they have not yet saved them.

Thanks

Hi, Parry

You can detect workflow changes by the following code when you load up a workflow or create a new one:

            ModelService modelService = wd.Context.Services.GetService<ModelService>();
            modelService.ModelChanged += (obj, arg) => {
                Console.WriteLine("workflow changed");
            };

wd is a instance of WorkflowDesiger.

Hope this helps
Regards
