The Bind Grid() method is our own function that we will create later on.
The Grid View Sort Event Args class has three important properties.
The Sort Expression property supplies the sort expression that you specified earlier for the column being sorted.

This argument provides the new page number that the user has selected via a property called New Page Index.
