RadGrid Update button works on laptop but not the server

[Darin]

The following is my grid which uses AllowAutomaticUpdates and updates the row as expected when the Update button is clicked. The problem is when I copy the code to the server, when I click the Update button, nothing happens. Clicking Edit brings up the Update and Cancel buttons as expected. Clicking Cancel takes the row out of Edit mode as expected. The environments appear to be the same. The code is the same. 

 What could be causing Update button not to fire on one computer but works fine on another? What do I look for?

Hi Darin,

Based on the provided information it would be hard to pinpoint what is causing the behavior. However, you could try couple of things that can narrow the search.

If AJAX is enabled on the page - disable it. You can easily do this by setting the EnableAJAX property of RadAjaxManager or RadAjaxPanel to false. Then run the page and see if there is a server-side error thrown when updating.

Also, you can handle the ItemUpdated event for the RadGrid and see if an error is returned from the database. The approach is illustrated in this example.
