Bind fields to functions

[teclioness]

Hi,

I am using gridview for the user to update rows. In a row, there sre
two columns, which need to be updated. When the gridview is to be
shown, the row should show the values from database. When user clicks
on edit link, should display the windows loginId in one column and in
second column, show the current datetime. When user clicks on update
link, should save these two column values to database as well as other
updated field values. I can't seem to find out how to set this up.

The Source doe is as follows:
