[ron klod]

Hi,

I have a datagrid and one of the columns is combobox, in the RowLoaded event I am trying to get a reference for that combox using the follwoing

private void dgConflictResolution_RowLoaded(object sender, RowLoadedEventArgs e)
        {

           OblicoreCombobox combo = (OblicoreCombobox)dgConflictResolution.ChildrenOfType<OblicoreCombobox>();

        }

 and it returnN null,

here is the XAML:

<TelerikControls:RadGridView x:Name="dgConflictResolution" ItemsSource="{Binding Conflicts, Mode=TwoWay}"  VerticalAlignment="Stretch"  AutoGenerateColumns="False" MultipleSelect="True" CanUserSelect="True" Margin="0,0,0,0" Grid.Row="1"
                                     RowIndicatorVisibility="Collapsed" RowDetailsVisibilityMode="VisibleWhenSelected" RowLoaded="dgConflictResolution_RowLoaded" >
            <TelerikControls:RadGridView.Columns>
                <TelerikControls:GridViewToggleRowDetailsColumn />
