1. What is the role of Composite Key here? Why did you used here in question?
2. What is the issue that you face while trying it?

It's a simple ADO.NET delete from database. If you have read of ADO.NET delete code then this should be easy for you. Just write it as you would for a normal case. Change the query of delete based the key or condition(s) you want to.
