Return false from the javascript function.
Here's some server side code that uses javascript to display a confirmation
message.
myDeleteButton.Attributes.Add("onclick", _
"return confirm('Are you sure you want to delete?');")
In this example, the Delete button will post back only if the person
confirms they want to delete. Otherwise your server code is never called in
response to the button click.
Here's a more detailed analysis of your options, including a free control
that can handle many of the options for you.

I have a small JavaScript event handler that runs when a Button is clicked.
This function is called before the postback. I would like to prevent the
execution of the postback in that function under a certain condition.
Possible?
