Adding Check Boxes to the TreeView

You can easily add check boxes to the C1TreeView control, check boxes can appear before text and allow users to select tree view items. The following XAML markup adds check boxes to the C1TreeView:

<c1:C1TreeView Name="C1TreeView1" Height="300" Width="200" >

    <c1:C1TreeViewItem IsExpanded="True" Margin="10">
