Silverlight 3 DataForm Validation with Templates

I have an SL3 application in which I am using DataForm to enter data. I want my form to look the way I like, so I use <dataControls:DataForm.EditTemplate>

and inside the template I have a nice form design.

The main problem is that inside the template, I have to use regular controls (like TextBox) instead of "field" controls (like DataFormTextField). they both work pretty much the same with a big difference when they get checked.

if I throw an exception on the property setter they are bound to, they both show the correct red sign and error, but if I decorate the property with validation attributes (for example [Required(ErrorMessage = "can't be empty!")]

), then only the DataFormTextField and the TextBox control show an error. in both cases my ErrorSummary control has an error in its collection, so I can see that the error is being taken into account ...

Any help is appreciated.

Are you using a template field?



   <df:DataFormTemplateField FieldLabelContent="Year"> 
      <df:DataFormTemplateField.DisplayTemplate> 
        <DataTemplate> 
          <TextBox Text="{Binding Year}" HorizontalAlignment="Left" /> 
        </DataTemplate> 
      </df:DataFormTemplateField.DisplayTemplate> 
      <df:DataFormTemplateField.EditTemplate> 
        <DataTemplate> 
          <TextBox Text="{Binding Year}" HorizontalAlignment="Left" /> 
        </DataTemplate> 
      </df:DataFormTemplateField.EditTemplate> 
    </df:DataFormTemplateField>
