I have a number of children property on each of my items in the TreeGridList, this list is currently an ObservableCollection.
If I have the children expanded in the grid, and then transition the number of children on the parent to 0 through the grid, the collection changed notification coming from the ObservableCollection causes the grid to try to revert the change that is under way (changing the number of children to 0). I am not sure how to resolve this (keep the 0 child count).
I have a very simple sample project but am not sure how to attach it. (I pasted the view item below).
reproduction steps - launch application, change child count on an item to 3, expand item, change child count to 0 (notice that the number of children remains 3).
Thanks for your help..

public class ViewItem
{
private static int NameID = 0;
public ViewItem()
{
this.Name = "ObjectName" + NameID++;
this.Children = new ObservableCollection<ViewItem>();
}
public ObservableCollection<ViewItem> Children
{
get;
set;
}
public string Name { get; set; }
public int NumberOfChildren
{
get
{
return this.Children.Count;
}
set
{
if (value == 0)
{
this.Children.Clear();
}
else
{
for (int i = this.Children.Count; i < value; i++)
{
this.Children.Add(new ViewItem());
}
}
}
}
}
