Get all workflow instances
You can also use the Workflow Services instance service to view all workflow instances that are running on a SharePoint site, list, or document library. The instance object that is returned contains information on the instance, such as when it was last updated, the current status, and any errors that may have occurred when it ran previously. Additionally, it provides a collection of name/value pairs that were submitted to the workflow from the custom initiation form.
To do this, start by using the GetWorkflowInstanceService method to get a reference to the instance service. Note that the WorkflowInstanceService provides several methods for obtaining the collection of running workflow instances:
- Enumerate . Accepts a workflow association (that is, a subscription)
as a parameter, and can be used to get all the instances that have
been created based on the specified association.
- EnumerateInstancesForSite : Gets a list of all workflow instances
that have been started on the SharePoint site that was set when
creating the original WorkflowServiceManager object.
- EnumerateInstancesForListItem . Accepts a list ID and item ID; use
this method to get all workflow instances that have been created on a
specific list item.
