[FIXED] How to disable postback on an asp Button (System.Web.UI.WebControls.Button)

Issue

I have an asp button. It's server-side so I can only show it for logged in users, but i want it to run a javascript function and it seems when it's runat="server" it always calls the postback event.

I also have a regular button (<input...>) not running at server and it works fine...

How can I make this button only run the javascript and not postback?

Solution

Have your javascript return false when it's done.

<asp:button runat="server".... OnClientClick="myfunction(); return false;" />
