Validation using the Mandatory attribute

Validation using the Mandatory attribute

  
Hello Everybody,
This is an unexpected issue.  I created a special value for a combo box and made the special value = 1.  I made the combo box mandatory(mandatory = true), so the user must select from the combo box.  The problem is when the user selects my special value, which is a valid entry.............the combo box still recognizes that as a null selection and outputs an error.  How do we prevent the combo box from outputting an error when the user selects my special value and just outputs an error when there is truly a null selection(user did not pick anything).
Thanks in advance!
Frank

Hi Frank,

Well that special value is after all a valid selection, so if you want to cause a validation error, you will have to do it on a server side validation.
Just like you were talking about other topic a couple days ago.
