GridViewDataColumn: IDataErrorInfo awareness

[Nils]

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{ get; set;}
    }

    public class Foo : IDataErrorInfo
    {
        public string this[string columnName]
        {
            get
            {
                return "Error";
            }
        }

        public string Error
        {
            get
            {
                return "Error!";
            }
        }

        public string Name { get; set; }
    }

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 ?

Hi Nils,

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.
Please give it a try and let me know how it works.

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