This is likely due to the order of when you're binding the gridview vs when you're looking for the new value.

Do you have viewstate enabled?  And if so, do you only bind your data to the gridview when it's not postback?  This could be a problem if you always bind, and not just when it's not postback.

Have you checked the value of the field in Request.Form ?

You can do that as follows:
for (int i = 0; i < gvGridView.Rows.Count; i++)
{
  GridViewRow r = gvGridView.Rows[i];
  TextBox tb = (TextBox)r.FindControl("tbStuff");
  var postedVal = Request.Form[tb.UniqueID];
}

Hi SmashAndGrab,

Use OnTextChanged event of the textbox in GridView which will solve your problem.

Check sample example:

@zephyr_hex  - thank you.  You were correct.

I was re-binding the GridView before running the update routine!  Must have missed that!

Thank you!
