Validation not working

[Sameer]

Hi Team,

I'm struggling with RadCombobox validation.

In my Entity metadata file, I have decorated the property with Required annotation like this:

[Required(AllowEmptyStrings = false)]
public string PlanType { get; set; }

In my Xaml, I have a Combobox like this

<telerik:RadComboBox x:Name="cbPlanType" DataContext="{Binding}" DisplayMemberPath="Name"
    EmptyText="&lt;plan type&gt;" 
    ItemsSource="{Binding PlanTypes}"
    SelectedItem="{Binding Path=SelectedEntity.PlanType, Mode=TwoWay, ValidatesOnExceptions=True, 
                    NotifyOnValidationError=True, UpdateSourceTrigger=PropertyChanged}"
    SelectedValuePath="Value" />

It is displaying the PlanTypes in combobox pretty well.
When something is null from DB, the combobox displays the EmptyText value which is also fine.
However, if I don't select anything from the combobox, it doesn't show validation tooltip.

FYI- I'm using SL5 with latest Telerik control suite.

Thankyou for your help.

Hello Sameer,

Could you please replace RadComboBox with a regular Silverlight ComboBox and tell us whether the validation is fired in the described case? Thanks
