title: gridview in bootstrap modal popup issue
body: <p>I used bootstrap modal popup and in that there is need to implement a gridview.
  Using update panel,I added gridview and databinding is working properly.
  In gridview row, there is a textbox where user can modify the existing values and update with a save button outside the gridview.</p>
  
  <p>But when I fire the Save button command at server side, I am not getting the updated values instead I am getting old values by looping gridview rows controls. </p>
  
  <p>How to get the updated values of from textbox in gridview inside bootstrap modal popup? I have used update panel also.</p>
  
  <p>Please suggest.</p>
