WorkflowRuntime.WorkflowIdled Event
Important
Some information relates to prerelease product that may be substantially modified before it’s released. Microsoft makes no warranties, express or implied, with respect to the information provided here.
Occurs when a workflow instance enters the idle state.
public:
event EventHandler<System::Workflow::Runtime::WorkflowEventArgs ^> ^ WorkflowIdled;
public event EventHandler<System.Workflow.Runtime.WorkflowEventArgs> WorkflowIdled;
member this.WorkflowIdled : EventHandler<System.Workflow.Runtime.WorkflowEventArgs>
Public Custom Event WorkflowIdled As EventHandler(Of WorkflowEventArgs)
Public Event WorkflowIdled As EventHandler(Of WorkflowEventArgs)
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();
}
}
Shared Sub Main()
Dim connectionString As String = "Initial Catalog=SqlPersistenceService;Data Source=localhost;Integrated Security=SSPI;"
Using workflowRuntime As New WorkflowRuntime()
Dim dataService As New ExternalDataExchangeService()
workflowRuntime.AddService(dataService)
dataService.AddService(expenseService)
workflowRuntime.AddService(New SqlWorkflowPersistenceService(connectionString))
AddHandler workflowRuntime.WorkflowCompleted, AddressOf OnWorkflowCompleted
AddHandler workflowRuntime.WorkflowTerminated, AddressOf OnWorkflowTerminated
AddHandler workflowRuntime.WorkflowIdled, AddressOf OnWorkflowIdled
AddHandler workflowRuntime.WorkflowAborted, AddressOf OnWorkflowAborted
Dim workflowInstance As WorkflowInstance
workflowInstance = workflowRuntime.CreateWorkflow(GetType(SampleWorkflow))
workflowInstance.Start()
waitHandle.WaitOne()
workflowRuntime.StopRuntime()
End Using
End Sub
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.
