Answer 1

Hi,

You can change the workflow status by using WorkflowControlClient.

Answer 2

Thanks Leo....

my problem is that i am using WorkflowApplication to run a workflow. i want to pause the workflow through a button . i am using wcf service on which i am having workflow application object.

in order to pause the workflow i can use workflowapplication.unload method .. but problem that i am facing is that how i can initalize the workflow with runtime id.. as if i write

workflowapplication wapp=new workflowapplication ()..

it automically assigns an id to it...i cant use callback or

InstanceContextMode.Single to have workflow application object state..

Answer 3

Hi,

Yes, the WorkflowApplication always assign a generated Id to it. As far as I know, there is no way to specify the runtime Id manually in WF4. We must retrieve the workflow instance's id and send it back to client for controlling workflow states.
