:-D

I have had some success, but not the answer I need yet.

I'm trying to validate two values in a database before a value is allowed to submit to the database. I have an employee entry form. I need to make sure that an emplyee's last name and first name is not in the database.

For example:

-------------------------|
Employees-------------|
-------------------------|
F_Name---|L_Name---|
-------------------------|
Bob_____|Jones_____|
Mary____|Hearts____|
-------------------------|

This is what I have so far any ideas...
if(L_Name!=null&&!provider.CheckUnique("L_Name",this)&&F_Name!=null&&!provider.CheckUnique("F_Name",this))  
errors.Add("L_Name",String.Format(Resources.strings.CCS_UniqueValue,"L_Name"));  
errors.Add("F_Name",String.Format(Resources.strings.CCS_UniqueValue,"F_Name"));

When I deliberatly enter a name that I know that exist in the database like "Bob Jones", an error explains that "Bob Jones" exist in the database.

However, if I enter "Bob" and attempt to submit, then explains that "Bob" exists in the database

or

if I enter "Jones" and attempt to submit, then explains that "Jones" exists in the database
