View 1 RepliesI have created a search page for web application that will allow a user to search the database based upon employee name or supervisor name. It is a multiple table database that is linked together by an unique employee number column, primary key in people and foreign key in supervisor. I have a parent/ child datalist used to display the record. When searching by the employee name it will return the record correctly if there is a record found. However, if I search by supervisor name and there is no match for the supervisor name, it will return all the records and create the parent datalist with all the employee details there, but the child datalist with the supervisor information is not display as there is no record with that supervisor name.
