I have a gridview with buttons in a column and I want those buttons to be 
triggers for an update panel further down on the page.  So for example, when 
a user clicks on the button in row 3, I want an async postback to occur and 
an update panel in a different section of the page to update and display "Row 
3 was clicked".  The gridview is outside of the update panel.

How can I accomplish this?  The update panel does not seem to support adding 
triggers to a RowCommand event on a grid view or for a button inside of a 
template column.  Is there a way in client script to enroll a particular 
control's click event into an async postback for an update panel instead of 
the normal postback?

Thanks for the help,
Joe
