Are themes visible at design time?

Question

This is my first experience with themes.

I've created a skin file for a textbox and the defined theme is only visible at runtime.

Is this the way theme works or I am missing something?

Answer 1

You should use StylesheetTheme property that can be set on page level or globally

Page Level

<%@ Page Language="C#" StylesheetTheme="MyTheme" %>

Global (web.config)

<system.web>
  <pages styleSheetTheme="MyTheme" />
<system.web>
