I have a number of fields that are Yes/No data types and the Display Control is a Textbox. I would like the default value of this field to be blank until the user enters Yes or No. Is this possible with this type of control? Also I'd like to know how the user could type just "Y" for yes or "N" for No. Also, if the field is marked "Yes" I would like the user to be forced to enter a date in another field. How can this be done. Thanks in advance.
