    According to the father  node,   how  to  make   all  it's child nodes  be   checked ?

    “RadTreeViewItem”  has  no  "IsChecked"  Property ,  how  to do ???

    The  code as below:
         private void rtv_BuildingList_Checked(object sender, Telerik.Windows.RadRoutedEventArgs e)
                if ((e.Source as RadTreeViewItem).HasItems)
                    foreach (RadTreeViewItem item in (e.Source as RadTreeViewItem).Items)
                        //item.IsC = true;

    Hello Starry,

     RadTreeViewItem has both IsChecked and CheckState properties. In all scenarios it is better to work with the CheckState property. This blog post describes their differences.
    As for making child items checked when their parent is checked, you only have to set the IsInTriStateMode = True.
