C# - Navigate Rows In DataGridView

This code snippet allows you to navigate through a DataGridView control. The navigation buttons select a row and the details button gets the values for the currently selected row and displays it in a message box.

1. // Place a datagridview control on the form
2. // Place five button controls on the form and name them as:
3. // FirstRecord, PreviousRecord, NextRecord, LastRecord, Details
