Hi,

Our client has reported an error produced on filter when item has any underscore. We are using Telerik 2012.2.607.40

If user clicks on checkboxes it filters items as expected but if user clicks on text it raises the following exception:

System.ArgumentNullException was unhandled
  Message=Value cannot be null.
Parameter name: element
  Source=Telerik.Windows.Controls
  ParamName=element
  StackTrace:
       at Telerik.Windows.Controls.ParentOfTypeExtensions.<GetParents>d__0.MoveNext() in c:\TB\117\WPF_Scrum\Release_WPF\Sources\Development\Core\Controls\Extensions\ParentOfTypeExtensions.cs:line 74

       at System.Windows.RoutedEventArgs.InvokeHandler(Delegate handler, Object target)
       at System.Windows.RoutedEventHandlerInfo.InvokeHandler(Object target, RoutedEventArgs routedEventArgs)
...

It is easy to reproduce with this code.

MainWindow.xaml
<Window x:Class="TestUnderscore.MainWindow"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:Controls="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.GridView" Title="MainWindow" Height="350" Width="525">
    <Grid>
        <Controls:RadGridView x:Name="RadGridView"/>
    </Grid>
</Window>

MainWindow.xaml.cs
namespace TestUnderscore
{
    /// <summary>
    /// Interaction logic for MainWindow.xaml
    /// </summary>
    public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
 
            var items = new ObservableCollection<string>();
            for (int i = 0; i < 50; i++ )
            {
                items.Add("Item_" + i);
            }
            this.RadGridView.ItemsSource = items;
        }
    }
}
