WorkflowRuntime.WorkflowIdled Event

Occurs when a workflow instance enters the idle state.

Namespace:  System.Workflow.Runtime
Assembly:  System.Workflow.Runtime (in System.Workflow.Runtime.dll)

public event EventHandler<WorkflowEventArgs> WorkflowIdled

The workflow run-time engine raises the WorkflowIdled event when the workflow instance enters an idle state; for example, when the workflow is waiting for a DelayActivity activity to complete.

For this event, the sender contains the WorkflowRuntime and WorkflowEventArgs contains the WorkflowInstance associated with the event.

For more information about handling events, see Consuming Events.

The following code example demonstrates how to use WorkflowRuntime functionality from a workflow host. The code associates the WorkflowIdled with an event handler, a method named OnWorkflowIdled.

This code example is part of the Canceling a Workflow sample.

static void Main()
{
    string connectionString = "Initial Catalog=SqlPersistenceService;Data Source=localhost;Integrated Security=SSPI;";

    using (WorkflowRuntime workflowRuntime = new WorkflowRuntime())
    {
        ExternalDataExchangeService dataService = new ExternalDataExchangeService();
        workflowRuntime.AddService(dataService);
        dataService.AddService(expenseService);

        workflowRuntime.AddService(new SqlWorkflowPersistenceService(connectionString));
        workflowRuntime.StartRuntime();

        workflowRuntime.WorkflowCompleted += OnWorkflowCompleted;
        workflowRuntime.WorkflowTerminated += OnWorkflowTerminated;
        workflowRuntime.WorkflowIdled += OnWorkflowIdled;
        workflowRuntime.WorkflowAborted += OnWorkflowAborted;

        Type type = typeof(SampleWorkflow1);
        WorkflowInstance workflowInstance = workflowRuntime.CreateWorkflow(type);
        workflowInstance.Start();

        waitHandle.WaitOne();

        workflowRuntime.StopRuntime();
    }
}
