yes, you can do that
OnClick="ServerButton1_Click"
OnClientClick="return confirm('its javascript code');"

All HTML Controls have OnClick and OnServerClick events ( ex: input button, img etc..)
All Web Controls have OnClick and OnClientClick events (asp:Button etc..)

OnClick is executed at client-side and done with

.
