Set UseSubmitBehavior to false, then use OnClientClick like this:

OnClientClick="ClearVals();return false;"

This will prevent the postback from occurring. You can also return a value from ClearVals to conditionally determine whether you want to post back or not:

OnClientClick="if (ClearVals()) return false;"

Not real obvious but it works.

But if you're not using server side button behavior in the first place you can also just use an HTML button, which doesn't post back to the server at all.
