SharePoint 2013 supports Workflow Manager workflows. Which means they totally different with 2010 workflows. In reality what happens is that we publish a subscription for the particular list. Though its been a while SharePoint 2013 has come, I have seen many people struggling without getting this done. So I thought its worth sharing a sample code snippet with an explanation.
To get a detailed explanation, we need to have a little understanding on the following classes.
WorkflowServiceManager - This is the class used for configuring and upgrading of an installation of a Microsoft Azure Workflow
WorkflowDeploymentService - This class manages workflow definitions and workflow activity authoring.
WorkflowDefinition - Represents a SharePoint workflow definition and includes the workflow properties.
WorkflowDefinitionCollection - Client object collection of WorkflowDefinition class.
WorkflowSubscription - Class responsible for having subscriptions to the external workflow hosts such as Azure workflows.
WorkflowServicesManager workflowServicesManager = new WorkflowServicesManager(currentWeb);
WorkflowDeploymentService workflowDeploymentService
= workflowServicesManager.GetWorkflowDeploymentService();
WorkflowDefinitionCollection workflowDefinitions
= workflowDeploymentService.EnumerateDefinitions(publishedDefinitionsOnly);
// We can loop through the definitions.
foreach (WorkflowDefinition workflowDefinition in workflowDefinitions)
{
if(workflowDefinition.DisplayName.Equals(expectedDefinitionName)
{
WorkflowSubscription workflowSubscription = new WorkflowSubscription(); workflowSubscription.DefinitionId = workflowDefinition.Id; workflowSubscription.Enabled = true; workflowSubscription.EventSourceId = listGuid; workflowSubscription.Name = workflowDefinition.DisplayName;
// Event types when the workflow need to trigger such as Item Adding, Update and Manual workflowSubscription.EventTypes = eventTypes; workflowSubscription.SetProperty("TaskListId", taskListID); workflowSubscription.SetProperty("HistoryListId", historyListID);
workflowSubscription.SetProperty("FormData, string.Empty); WorkflowSubscriptionService workflowSubscriptionService
= workflowServicesManager.GetWorkflowSubscriptionService(); workflowSubscriptionService.PublishSubscriptionForList(workflowSubscription, listGuid); }
}
Hi Author,
ReplyDeleteMay I ask a question?
I confuse about TaskListId, HistoryListId
So how to create or initialize these variables
Thanks
