Hi all,

One of the limitations of the GridView control is that the built-in 
delete processing doesn't prompt for confirmation -- something thats 
very important for a user interface. True, you can add server side 
logic for this, but its much more reassuring to have a Javascript 
confirmation window open up and prompt. There are several techniques 
for doing this, just google 'Gridview delete confirm' to see them. 
I've figured out one which does not involve adding logic to the GridView 
setup, so there are fewer moving parts. And, it still preserves the ViewState.
There is a small amount of C# code to perform the actual record delete, but 
this is mostly a client-side/Javascript technique. 

The sample application with source is available at

Hope it helps.

John
