post - Can I create an ASP.NET ImageButton that doesn't postback?

Question

I'm trying to use the ImageButton control for client-side script execution only. I can specify the client-side script to execute using the OnClientClick property, but how do I stop it from trying to post every time the user clicks it? There is no reason to post when this button is clicked. I've set CausesValidation to False, but this doesn't stop it from posting.

I know this problem has already been answered but a simple solution is to return false from the HTML onclick method (i.e. the ASPX OnClientClick method) e.g.

<asp:ImageButton ID="ImageNewLink" runat="server" 
 ImageUrl="~/images/Link.gif" OnClientClick="DoYourStuff(); return false;"  />

Returning false stops the browser from making the request back to the server i.s. stops the .NET postback.
