title: ASP .Net Gridview rowupdated - can it happen before the page load?
body: <p>Here's the scenario:
  -Gridview control
  -Calendar control</p>
  
  <p>I only want the calendar to show if a specific item is chosen in the drop down list which is in a gridview. When the grid view row is updated I want to change whether or not the calendar is visible. The calendar's visibility only shows correctly on the next post back.</p>
