Is it possible to use a gridview with textboxes in all rows?

I have a project that requires me to allow a user to update 24 rows and 20 columns at one time. This is based on the hours in the day. However, the user does not wat to press an edit button on each record. an example is a spreadsheet with 24 rows. each row has eight 20 columns. each column needs to be filled with data. I would like to have text boxes for each column in every row. Can this be done without tables? if so, please provide a code sample.

Thanks.
