How to filter the source list of the gantt through a CollectionViewSource?

You could, optionally, let a CollectionViewSource manage your source list and bind it's View to the FlexyGantt as follows.

ObservableCollection<Team> source = SampleResourcesData.GetSampleData();

cvs = new CollectionViewSource();

cvs.Source = source;

cvs.Filter += cvs_Filter;

this.fxgantt.ItemsSource = cvs.View;

And in the Filter handler, apply your custom filters:

void cvs_Filter(object sender, FilterEventArgs e)

{

Team team = e.Item as Team;

if (team.TName.Contains("1"))

e.Accepted = true;

else

e.Accepted = false;

}

The filtered view can then be seen in the gantt.
