Using Checkbox in datagrid and fire checked event?

Question

Hai ,
   I placed on checkbox inside the datagrid. I am having one database, having one table, have the field name confirm_field. In the  confirm_field datatype is bit. I need to update the  confirm_field field from the asp.net web page. I expect, if i checked the checkbox in datagrid, I need to update the database  confirm_field, checked row value to true, other wise unchecked it will be false. Please give a solution.
