OnWorkflowActivated Class (Microsoft.SharePoint.WorkflowActions)

Responds to the event Windows SharePoint Services raises when a new workflow instance is initiated for an item.

Namespace: Microsoft.SharePoint.WorkflowActions
Assembly: Microsoft.SharePoint.WorkflowActions (in microsoft.sharepoint.workflowactions.dll)

Syntax

Visual Basic (Declaration)

<ActivityToolboxDisplayAttribute("VSTTSharePointWorkflow", True)> _
<ToolboxItemAttribute(GetType(ActivityToolboxItem))> _
<ToolboxBitmapAttribute(GetType(OnWorkflowActivated), "Resources.OnWorkflowActivated.bmp")> _
Public NotInheritable Class OnWorkflowActivated
    Inherits HandleExternalEventActivity

Visual Basic (Usage)

Dim instance As OnWorkflowActivated

[ActivityToolboxDisplayAttribute("VSTTSharePointWorkflow", true)] 
[ToolboxItemAttribute(typeof(ActivityToolboxItem))] 
[ToolboxBitmapAttribute(typeof(OnWorkflowActivated), "Resources.OnWorkflowActivated.bmp")] 
public sealed class OnWorkflowActivated : HandleExternalEventActivity

Remarks

An OnWorkflowActivated activity must be the first activity in a Windows SharePoint Services workflow.

This activity responds to the ISharePointService.OnWorkflowActivated event. Windows SharePoint Services raises this event activity when a workflow is initiated for a SharePoint item. This activity initializes the correlation between the workflow id and the correlation token.

The OnWorkflowActivated event is valid only as the first activity in a workflow. Windows SharePoint Services ignores OnWorkflowActivated activities placed at any other position in the workflow.
