    I have a combobox like below and i need to have a required field validation on it. 
    <
    telerik:RadComboBox x:Name="combobox" SelectionChanged="combobox_SelectionChanged" IsTextSearchEnabled="True" Width="120"
                                                    telerik:TextSearch.TextPath="Kode" Margin="2,0,0,0" IsEditable="True" IsReadOnly="True" SelectedItem="{Binding Path=SelectedItem, Mode=TwoWay, UpdateSourceTrigger=Explicit, NotifyOnValidationError=true, ValidatesOnExceptions=true}" TextSearchMode="Contains" CanAutocompleteSelectItems="True"  >
                                    <ItemsControl.ItemTemplate>
                                        <DataTemplate>
                                            <Grid>
                                                <Grid.ColumnDefinitions>
                                                    <ColumnDefinition Width="50" />
                                                    <ColumnDefinition Width="300"/>
                                                    <ColumnDefinition Width="300"/>
     
                                                </Grid.ColumnDefinitions>
                                                <TextBlock Text="{Binding Kode}" Grid.Column="0"/>
                                                <TextBlock Text="{Binding Nederlandse_omschrijving}" Grid.Column="1"/>
                                                <TextBlock Text="{Binding Franse_omschrijving}" Grid.Column="2"/>
                                            </Grid>
                                        </DataTemplate>
                                    </ItemsControl.ItemTemplate>

    DummyComboBox.ItemsSource = DummyCodeList.Load()
    The load event returns a list of Objects (List<DummyObject>)
    I can't quite get the validation working. 
    Any suggestions ?
