How do I update One table in a DataGridView that was populated using Two Tables?

I have populated a DataGridView using a SQL JOIN SELECT statement pulling data from two tables in the same DataSet. After the end user makes changes in the DataGridView, I need to UPDATE only One of the tables.

What is the most efficient way of handling this?

If your gridview contains an Id column for the record that you want to update in one particular table then you can write a simple update statement to upddate the record.
Update table
set fields = value1
where Id_field = (IdField from datagridview)
