adding a column with textbox inside from code behind
<p>I have a gridview that I want to add a textbox to the row that is clicked on.  I have a button on each row, when clicked I want a column with a textbox added to that row.  Which I then can type in and save to database.  </p>

<p>I have found code online but some of the objects that are defined I don't have for some reason.</p>

<p>Any ideas?</p>
