Hi All,
           I am currently adding a telerik silverlight gridview to my screen and i have few validations (mandatory fields) to be done when user enters data in the grid. I have used
ValidatesOnExceptions=true and NotifyOnValidationError=true for doing the validation and throwing exceptions in the setter of the bound properties when the data entered is empty. This will show the tooltip for the controls which are failing the validation. All these are working fine while updating the existing records in the gridview.

But these validations are not happening when i am adding a new row, without entering any value in the mandatory fields and changing the selection to some other row. Do you have any suggestions for firing these validations when i am changing the selected row in the gridview?

Regards,
Dhileep

Hello Dhileep Kumar Sampath,

My first guess is that you are using nested properties which are not created when you add new row, that's why code inside setters of these properties is never reached. If this is not your scenario, please elaborate a little bit.
I need some more information about definition of the column that causes the problem and also definition of your business object.
