Dear experts,

For my Caliburn.Micro application, I am trying to apply validation described here:

http://www.lyquidity.com/devblog/?p=71

But I have a problem: when I explicitly bind a field rather than relying on naming convention (e.g. to change UpdateSourceTrigger from default to something else), the validation stops working. Here is an example:

<TextBox x:Name="Url" MaxLength="255" Text="{Binding EdiProfileDetail.Url, UpdateSourceTrigger=LostFocus}"
                 Grid.Row="11" Grid.Column="1" Style="{StaticResource DetailTextBox}" />

Maybe somebody could help me with this?

Thanks.

ok so you have binding and convention occurring.  I would say drop the convention and go twoway for the Mode on the binding.  I  am assuming since EdiProfileDetail is a property on your viewmodel for this screen, and changes made should bubble correctly.

Thanks for your answer. 

I also realized I needed to explicitly set ValidatesOnDataErrors=True
