I am doing a tutorial where you use a templatefield in the gridview control to call a function.

I don't understand the code for the function. What is the object Northwind.EmployeesRow?

This is the tutorial I am doing.

And this is the code for the function.

Protected Function DisplayDaysOnJob(ByVal employee As Northwind.EmployeesRow) As String



        If employee.IsHireDateNull() Then

            Return "Unknown"

        Else

            ' Returns the number of days between the current

            ' date/time and HireDate

            Dim ts As TimeSpan = DateTime.Now.Subtract(employee.HireDate)

            Return ts.Days.ToString("#,##0")

        End If

    End Function
