Hi,
Previously I was using this code in WPF .net 4.0 framework and was working correctly.
Code at RowLoaded Event: 
TreeListViewRow row = e.Row as TreeListViewRow;     Binding binding = new Binding("IsExpanded") { Source = row.Item };    binding.Mode = BindingMode.TwoWay;    row.SetBinding(TreeListViewRow.IsExpandedProperty, binding); 
which indirectly calls the
RowIsExpandedChanging event somehow.
But now when I migrated to .net 3.5 framework, due to some limitations, the same code was not working.
Now it is not calling the RowIsExpandedChanging event.
Please suggest me how to overcome from this problem, is there any other way to do the same in .net 3.5.
Thanks in Advance.
