The TasksLoaded event is triggered if the Load method has finished.


// Load list of tasks

Session session = ...;

Tasks.TasksLoadedEvent handler = null;

handler = (s, args) =>


session.Tasks.TasksLoaded -= handler;

Data = args.Data;



session.Tasks.TasksLoaded += handler;

public Dictionary<int, List<int>> filter = // This is a filter. Here you specify, what tasks should be retrieved

 new Dictionary<int, List<int>>() {

   { 11175,   // This is the Diagram Id that holds the Task.

     new List<int>() { 72 } // This is a list of Task Id's inside the diagram.



// Skip all finished tasks and retrieve process variables Number and FormData

session.Tasks.Load(DateTime.UtcNow, DateTime.MaxValue, filter, new List<string>() { "Number", "FormData" });
