Expand and Collapse from code

Hello Telerik community, I have a very simple question which I can't seem to resolve on my own for some reason. When my program used to use telerik RadGridView control, I had this code to expand and collapse my datagrid

private void expandCollapseButton_Click(object sender, RoutedEventArgs e)
{
            if (this.inputParametersDataGrid.RowDetailsVisibilityMode == Telerik.Windows.Controls.GridView.GridViewRowDetailsVisibilityMode.Visible)
            {
                this.inputParametersDataGrid.RowDetailsVisibilityMode = Telerik.Windows.Controls.GridView.GridViewRowDetailsVisibilityMode.Collapsed;
            }
            else if (this.inputParametersDataGrid.RowDetailsVisibilityMode == Telerik.Windows.Controls.GridView.GridViewRowDetailsVisibilityMode.Collapsed)
            {
                this.inputParametersDataGrid.RowDetailsVisibilityMode = Telerik.Windows.Controls.GridView.GridViewRowDetailsVisibilityMode.Visible;
            }
}

but now  I am using the TreeListView control in Silverlight 3 on VSTS 2008 SP1. How would I achieve the same effect using a expand/collapse button?

Nevermind, I figured it out

bool isExpanded = false;
private void expandCollapseButton_Click(object sender, RoutedEventArgs e)
        {
            if (isExpanded == false)
            {
                this.inputParametersTreeListView.ExpandAll();
                isExpanded = true;
            }
            else
            {
                this.inputParametersTreeListView.CollapseAll();
                isExpanded = false;
            }
        }
