Solution 2

similar to Mark's, but what I usually do it fire the "delete" functionality from the server.

Therefore, by modifying his JavaScript a smidge:

btn.Attributes["onclick"] = "javascript: return confirm('Do you want to delete?');";

By passing the confirm (which gives a true/false value as a result) directly to the onclick handler, if you return a cancel/false attribute, the onclick doesn't complete and the form submittal will not occur.

Since the OP gave no details as to what the delete function was I didn't make any assumptions that a postback was necessary/desired.
