title: c# & ASP.NET Gridview- Textbox data update in DB
body: <p>I have a grid view with about six columns in which one of those columns is a text box.</p>
  
  <p>User may enter a value in the texbox and when he clicks on Submit button(this button is not within the gridview) that single value has to be updated into the database. All other columns in the gridview will be retrieved from the DB. But this one column has to updated into DB. User may enter data for one row or all the rows (records) for this editable column.</p>
  
  <p>Whenever there is some text change event for that textbox in gridview, I need to update the data for that particular record.</p>
  
  <p>Please suggest as to how to get the value of that particualar column when many rows are edited.</p>
  
  <p>Thanks in advance. </p>
