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 runtime 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, sender will contain the WorkflowRuntime and WorkflowEventArgs will contain the WorkflowInstance associated with the event.

For more information about handling events, see Consuming Events.

The following code example demonstrates how you can 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 SDK sample from the Program.cs file. For more information, see Canceling a Workflow.

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();
    }
}
