Hi Bala;

You just need to bind the TextBox to the Entity's property and set NotifyOnValidationError=true. 

For example, using our NorthwindIB Database example, to bind a TextBox to the Employee.City property, the XAML file would look like this:

Text="{Binding City, Mode=TwoWay, NotifyOnValidationError=true}"

Hope this helps.

Denis
