This worked for me (the accepted answer did not)

<asp:Button id="DeleteButton" runat="server" Text="Delete" 
OnClientClick="if (!confirm('Are you sure you want to delete?')) return false;">
</asp:Button>

You can add the javascript to the OnClientClick() event of the button... the key is to return false if you want to cancel the event. If you return false, the OnClick will not fire. 

<asp:Button id="DeleteButton" runat="server" Text="Delete" 
            OnClick ="delete_clickhandler" 
            OnClientClick="return confirm('Are you sure you want to?');" />

Alternately, you can call a method in javascript

<asp:Button id="DeleteButton" runat="server" Text="Delete" 
            OnClick ="delete_clickhandler" 
            OnClientClick="return MyDeleteConfirm();" />

Where MyDeleteConfirm() does something more elaborate, but returns false if you don't want to delete.
