[Solved] Hierachical Grid, GridViewColumnSelect and Delete

[UGH!!]

What I'm trying to accomplish here is a in a hierachical grid, with the child grid using a gridviewcolumnselect populated with an observablecollection. When I select the header to check all the items in the childgrid, I want to delete them and remove them in the observablecollection. Not getting it to work exactly right. The item is not visibly removed from the observablecollection - although the record gets deleted. And the removal from the observablecollection triggers another selectedchangeevent.  Here's my code .... any help would be soooo helpful.

private void _childGrid_SelectionChanged(object sender, SelectionChangeEventArgs e)
        {
            if (setPrompt == false)
            {
                RadWindow.Confirm("Are you sure you want to remove the selected instance(s)?", (s, args) =>
                 {
                     if (args.DialogResult.HasValue && args.DialogResult.Value)
                     {
                         RadGridView gv = e.OriginalSource as RadGridView;

                         foreach (var item in gv.Items)
                         {
                             var row = gv.ItemContainerGenerator.ContainerFromItem(item) as GridViewRow;
                             if (row != null)
                             {
                                 if (row.IsSelected == true)
                                 {
                                     UsersTableItem ti = row.DataContext as UsersTableItem;
                                     string selectedInstanceID = ti.InstanceID.ToString();

                                     AppInstances.RemoveAppInstance(selectedInstanceID);
                                     ti.Children.Remove(ti);
                                     //ViewModel.LoadData();
                                 }
                             }

                         }
                     }
                 });
            }
            setPrompt = true;
        }
