Insertion Multiple records into database using asp.net

Question

Insertion of Multiple Records into database using Asp.Net? 

 When i select multiple check boxes in grid view, that it is shown on another grid view of the selected rows, when I submit all those records only the last record value gets inserted but not other records into database.

First GridView: From Database-1

 
Second GridView: To Database-2
 

 
Where I am filling out the details of text boxes and Pay it out.
 
Then it shows Paid successfully.

 
 
While in database it shows only the last RequestNo is inserted, other two records is not inserted..

 

 
 
As I need to insert all three records of RequestNo to be inserted in database.

So, if there's a solution or any answer please send me it......
