Here I am going to show Alphabetic Paging using
gridview control. Here user can find data according to respective alphabet link
and also can find all the data by clicking all link.
Create a table Customers with column Cus_Code varchar(50), Cus_Name varchar(50),
Cus_address varchar(MAX), Cus_sal int.
