I have a WIndows form in a C# application with a datagrid view called dgvCustomers.  I now need to turn this into a lookup window so it will return the Customer number. There are only two fields on this form, CUSTNMBR and CUSTNAME. I am thinking of giving them two options to return a value. One would be with a button with text Select and the other would be a double click event. I assume the code would be the same between these two methods.  The query behind this dgv is:

SELECT CUSTNMBR,CUSTNAME FROM CUSTOMERS ORDER BY CUSTNMBR

This query is used to populate a data table(Customers) and then the datagridview(dgvCustomers) is populated using this data table.

What is the proper method to identify the cell to which the user is currently pointing and returning the customer number?
