Hi.
I am using the following code:
    public partial class Window1 
    { 
        public Window1() 
        { 
            InitializeComponent(); 
            this.Foos = new ObservableCollection<Foo>(new[] 
                        { 
                            new Foo { Name = "1" }, 
                            new Foo { Name = "2" }, 
                        }); 
        } 
 
        private void Window_Loaded(object sender, RoutedEventArgs e) 
        { 
            this.DataContext = this
        } 
 
        public ObservableCollection<Foo> Foos{ getset;} 
    } 
 
    public class Foo : IDataErrorInfo 
    { 
        public string this[string columnName] 
        { 
            get 
            { 
                return "Error"
            } 
        } 
 
        public string Error 
        { 
            get 
            { 
                return "Error!"
            } 
        } 
 
        public string Name { getset; } 
    } 

in combination with this xaml:
<Window x:Class="WpfApplication6.Window1" 
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
    xmlns:telerik="clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls.GridView" 
    Title="Window1" Height="300" Width="300" 
        Loaded="Window_Loaded"
    <telerik:RadGridView ItemsSource="{Binding Path=Foos}" 
                         AutoGenerateColumns="False"
        <telerik:RadGridView.Columns> 
            <telerik:GridViewDataColumn Header="Name 1" 
                                        DataMemberBinding="{Binding Path=Name, ValidatesOnDataErrors=True}" /> 
            <telerik:GridViewColumn Header="Name 2"
                <telerik:GridViewColumn.CellTemplate> 
                    <DataTemplate> 
                        <TextBox Text="{Binding Path=Name, ValidatesOnDataErrors=True}" /> 
                    </DataTemplate> 
                </telerik:GridViewColumn.CellTemplate> 
            </telerik:GridViewColumn> 
        </telerik:RadGridView.Columns>         
    </telerik:RadGridView> 
</Window> 

The second TextBox "Name 2" does show the DataErrors fine. However the GridViewDataColumn ("Name 1") seems unaware of the DataErrorInfos.

Am I missing something or is the GridVioewDataColumn unaware of IDataErrorInfo ?

Thank you for pointing this out. I've updated your Telerik points accordingly.
This issue is already fixed and will be available with the today's latest internal build.

Thanks for the quick answer.
Have you seen that GridViewComboboxColumn is also affected ?
(And possibly more GridView...Columns)
