Table modify in BSP

Hello All,

I have a tableview with entries from a Database table.

I have 3 columns in this table view.

Out of all the 3 columns ,I made only one column editable ( 2nd column ).

1, Now if i change the value in the 2nd column the internal table of the table view must get modified with the changed value .

After that I'll modify the corresponding database table

I want this to be acheived without selecting any line of the tableview after the changes.

can it be done ? I want this is to be chieved after a button "SAVE' on page , not on table view.

I am able to modify internal table on a table view event but i am not able to find data on Click of SAVE button lying on Page

Please let me know how to do this
