My requirement is to present data in a tabular form, and let user edit
the values of one of the column for all the rows presented, and then
when Submit button is clicked I have to save edits of all these rows.

Most of the articles I looked at were talking of editing datagrid row
one at a time, which will not work in this scenario. I tried to define
the Template column I want to edit as a <asp:TextBox>, but then I
don't know how to get the value for each of the row when Submit is

Can some one help?

Thanks a bunch
