TreeListView Row Visibility

[Arinto]

Hi there, 

Is that possible to bind the Visibility property of TreeListView Row into a ViewModel's property?

For example here is the format of the ViewModel

public class EntryViewModel
{
    private String _name;
    private ObservableCollection<EntryViewModel> _items;
    private Boolean _isVisible;

    public EntryViewModel(String name, Boolean isVisible = true)
    {
        _name = name;
        _items = new ObservableCollection<TSEntryViewModel>();
        _isVisible = isVisible;
    }

    public String Name
    {
        get { return _name;}
        set { _name = value; }
    }

    public ObservableCollection<EntryViewModel> Items
    {
        get { return _items; }
        set { _items = value; }
    }

    public Boolean IsVisible
    {
        get { return _isVisible; }
        set { _isVisible = value; }
    }
}

So, is that possible to set the Visibility  property of TreeListView row to Collapsed when IsVisible value is false?
I've tried to look for some APIs here but can't find any API that can serve my purpose.

Hello Arinto,

Modifying rows' Visibility will most likely result in the appearance of blank spaces into your TreeListView and other severe visual issues. As a rule of thumb, directly messing with the visual tree is rarely a good idea. I would strongly advise you to utilize a filtering approach, in order to display only the items that satisfy your condition.
