title: asp.net webforms ajax update gridview
body: <p>We have a gridview with quite a large amount of information (100s or rows and columns) which we need to improve preformance of.</p>
  
  <p>Currently to fix some performance issues we have made the gridview have no edittemplate and instead double clicking on a cell will bring up a dropdown of the available options that is retrieved using webmethods and populated using jquery dynamically, after an option is choosen in the dropdown we set teh value in the html to the value of the selected option.</p>
  
  <p>We are having problems subsequently sending this changes back to the server, we have a button on the page that causes a postback to the server but the changes that we have made via the jquery functionality aren't available when we loop through the gridview items they still have the same values as previous.</p>
  
  <p>Are we going about this the wrong way in terms of populating/updating how can we achieve this?</p>
  
  <p>Aside: I know we should probably limit the bounds of the grid but at the moment this is not an option</p>
