Self-reference data

[Russ]

Is it possible to use self referenced data in the WPF Gantt similar to this? https://ej2.syncfusion.com/aspnetcore/documentation/gantt/data-binding/#self-referential-data-binding-flat-data

I have an existing database with a table of Tasks containing (among many other properties)  TaskID and ParentID (which the TaskID of the parent task).  

Thanks

I've worked around this by creating a hierarchical observable collection of tasks and nested child tasks so hardly a massive issue but would still like to know if I'm missing something that could let me avoid that step.

Thanks

Hi Russ,

Greetings from Syncfusion.

Query:  Is it possible to use self referenced data in the WPF Gantt ?

We have analysed your requirement and we don't have the support to achieve your requirement.

If you need to define the parent-child relationship between tasks, you will add the child task to the parent task as per the below code snippet.

[ViewModel.cs]: 

public ObservableCollection<Task> GetData() 

        { 

            var data = new ObservableCollection<Task>(); 

             data.Add(new Task() { Id = 1, Name = "Scope", StDate = new DateTime(2011, 7, 8), EndDate = new DateTime(2011, 7, 24), Complete = 40d }); 

            data[0].ChildTask.Add((new Task() { Id = 2, Name = "Determine project office scope", StDate = new DateTime(2011, 7, 15), EndDate = new DateTime(2011, 7, 17), Complete = 20d, })); 

            data[0].ChildTask.Add((new Task() { Id = 3, Name = "Justify Project Offfice via business model", StDate = new DateTime(2011, 7, 19), EndDate = new DateTime(2011, 7, 21), Complete = 20d })); 

            data[0].ChildTask.Add((new Task() { Id = 4, Name = "Secure executive sponsorship", StDate = new DateTime(2011, 7, 21), EndDate = new DateTime(2011, 7, 24), Complete = 10d, })); 

            data[0].ChildTask.Add((new Task() { Id = 5, Name = "Secure complete", StDate = new DateTime(2011, 7, 24), EndDate = new DateTime(2011, 7, 24), Complete = 10d })); 

... 

 

           return data; 

        }
