I have a sequential workflow which creates a task that contains the custom url to a custom webpart.
The web part provides the option to select different statuses. When the user selects 'Approved' I want to mark the respective task as completed.
How can I get this done in c#?
you can get the idea from the code below
SPSite site = new SPSite("http://servername/");
using (SPWeb web = site.OpenWeb())
{
SPList list = web.Lists["TestList"];
SPListItem item = list.GetItemById(22);
SPWorkflow workflow = item.Workflows[0];
SPWorkflowTask task = workflow.Tasks[0];
Hashtable ht = new Hashtable();
ht[SPBuiltInFieldId.Completed] = "TRUE";
ht["Completed"] = "TRUE";
ht[SPBuiltInFieldId.PercentComplete] = 1.0f;
ht["PercentComplete"] = 1.0f;
ht["Status"] = "Completed";
ht[SPBuiltInFieldId.TaskStatus] = SPResource.GetString(new CultureInfo((int)task.Web.Language, false), Strings.WorkflowStatusCompleted, new object[0]);
ht[SPBuiltInFieldId.WorkflowOutcome] = "Approved";
ht["TaskStatus"] = "Approved";
ht["FormData"] = SPWorkflowStatus.Completed;
web.AllowUnsafeUpdates = true;
SPWorkflowTask.AlterTask((task as SPListItem), ht, true);
}
