Get all the WorkflowTask associated with a ListItem

Sometimes, we need to access all the Task associated with an SPListItem for a particular workflow. Following quick code is helpful.

//using the namespace

using Microsoft.SharePoint.Workflow;


SPSecurity.RunWithElevatedPrivileges(delegate
                    {
                        using(SPSite site = new SPSite(SPContext.Current.Web.Url))
                        {
                            using (SPWeb web = site.OpenWeb())
                            {
                                SPList lsPM = web.Lists["MyList"];
                                SPListItem lstMyList =   lsPM.GetItemById(IDOfTheListItem);
                                
                                SPWorkflowFilter filter = new SPWorkflowFilter();
                               //Filter task based on the Workflow Status
                               filter.InclusiveFilterStates = SPWorkflowState.Running; 
                               SPWorkflowTaskCollection workTaskColl = web.Site.WorkflowManager.GetItemTasks(lstMyList , filter);
                             
                              foreach (SPWorkflowTask task in workTaskColl)
                              {
                            if (task != null)
                            {
                                        // Loop through the Task Items
                            }
                        }
                            };
                        }
                    });


Hope this helps...........

Hi,

Hi Roopa,
This code shall get all the Tasks associated with an SPListItem.
//Filter task based on the Workflow Status
filter.InclusiveFilterStates = SPWorkflowState.Running; // This shall help you to filter tasks based on the status of the task.
This should work in all case if the List has any associated workflow tasks.

Regard....
