DatagridView and Database

Question

Hi!!!

I have a gridView on the form in my windows application and in the database I have a table "student" having fields " c_id,sec_id,sub_id,s_id,s_name". On button click(Add) I am executing the query for saving data to database.

In gridView there are 3 column headers namely- "Roll No", "Student Name", "Marks".

Firstly , I want that when I click on button(Add) ,then "s_id" should display in "RollNo" column , "s_name" should display in "Student Name" column and "Marks column" should be editable in gridview.  

Secondly, how can I add marks in Marks column in datagrid during runtime and those marks should save in table named "result" in marks column.

I hope my problem is clear.

Kindly give some solution...........
