Update Panel Mode in Ajax

Here is the interesting point to Discuss with you about the Update Panel Mod. Hope Everybody Likes this.

  

There are two Mode of Update panel in Ajax. 

Mode="Conditional' causes the updatepanel to update when one of three things happen:

1) If a Control within the Update panel causes the actual Post back

2) If a Trigger on the Update panel updates

3) If someone calls "Update()" on the Update panel itself

Otherwise, it won't update and refresh.  When it is set to always, however, it will always refresh.
