| What to choose? |
We have seen several scenarios throughout this article that
discuss how to handle UserControls when AJAX is to be added to a website. One
would ask which scenario is best to follow. Well the normal answer would be it
depends on the situation you are experiencing. However, we do not like normal
answers and we would be strict in saying that, it is recommended to leave the
UserControls intact and add your AJAX controls to the host pages themselves.
Then you can either use Triggers or a programmatic call to update method of the
UpdatePanel for refreshing the content of any UpdatePanels.

Thanks

Great Article!
I have the update panel on the page and the user controls inside the update panel.
I create a property inside the usercontrol that accesses a control, Say the gridviews Tooltip or Pagesize or ...
When I try to set the property on page declaratively I get an error:
Object reference not set to an instance of an object.
I've seen this problem posted in other places but no solution.
Have you run into this and do you have a work around.
Thanks!

As usual, you did a great job!
I loved the fact that you showed all the possible combinations you can have with a gridview user control and AJAX. And the sample works really fine!

Very well summarized, thanks. I agree, good use of events and generics.
Also, there's a small typo in Listing 5: OrderList UC's UpdatePanel ID should be 'AjaxPanel'.
