Hello EMRE ANDIC,
Here is a modified sample code:
sender, RoutedEventArgs e)
i = 0; i < 5; i++)
rti.Header = i;
j = 0; j < 3; j++)
RadTreeViewItem item =
item.Header = j;
item.Tag = j;
//MyRadTreeView is declared at XAML code.
sender, Telerik.Windows.RadRoutedEventArgs e)
The error that was in your code was that the Tag property was not assigned to the child items, but to their parent.
