BobbyeM71hxwDid you know… How to scope Theme

Themes are a way to define properties of pages and controls, and can be used to provide consistent look across pages. There are several different levels of applying a theme to an individual control, a page, or an application.

1. Control Level
Define a named skin (an entry in a .skin file having the SkinID property set) and then apply it to an individual control

2. Page Level
A defined theme can be applied to an individual page by specifying the Theme orStyleSheetTheme attribute of the @Page directive of the page

3. Application Level
To define the theme for the whole application, set the theme attribute of the pages element in the web.config file of the application

4. Global Level- Theme can also be applied globally to all the web sites on the same server. Global themes are defined the same way as Page themes, except that they’re defined in aTheme folder that is global to the server. Then you set the theme attribute of the pages element in the machine.config file.

Do you wonder if there is any difference between setting the Theme and StyleSheetThemeattribute of a @Page directive? Yes, there is. The difference is the precedence of the themes specified by the attribute. If you use the Theme attribute, the local settings will be overwritten by the Theme settings. If you use the StyleSheetTheme attribute, the local settings will be applied, regardless of what being defined in the Theme folder.

Also, a point that is worth mentioning is the designer of Visual Studio doesn’t support theTheme attribute. If you want to use the designer when developing your page, you might consider using the StyleSheetTheme attribute, then switch to using the Theme attribute for deployment.
