Just wanted to post up a quick page I found when I was looking to prevent double clicking on a submit button.

This approach is fairly simple; just use two buttons and update the visibility to achieve the affect.
Here's a link to a 4 guys series (much like the famous 18 part series on the DataGrid) that goes over the ListView control. It's new to .net as of 3.5.
It looks like it has the power of the DataGrid functionality, plus some, with the power to control the rendering like the Repeater (for you table haters).
I'm just getting ready to use it for the first time so I'm anxious to see how it's going to come out in the end.
