Forcing validation style to appear on a combo box

[Ian]

I have the following combo box:

                            <telerikInput:RadComboBox x:Name="CmbIncidentType" 

                                Grid.Row="2" 

                                Grid.Column="1" 

                                DisplayMemberPath="Name" 

                                SelectedValuePath="Value" 

                                BindingValidationError="OnBindingValidationError"

                                ItemsSource="{Binding IncidentTypeList, Mode=TwoWay}"

                                SelectedItem="{Binding SelectedIncidentType, Mode=TwoWay, NotifyOnValidationError=True, ValidatesOnExceptions=True}"/>

The object property that this is bound to -- SelectedIncidentType -- is correctly validating and OnBindingValidationError event is firing, which is allows me to see that the right exception message is being passed.  The problem is that the combo box doesn't have a red outline and and a pop up error message like the text box.  

Is there some property that I need to set to make the default validation color scheme appear?

Hello Ian,

The problem is that RadComboBox does not have validation states in its template. We have this feature in our plans for Q3 2009 and it is almost ready, so you will be able to get the updated assemblies next week when we release Beta 2.
