The Page directive includes the attribute Theme and StylesheetTheme.You can use both to apply themes to a page. So, the question is: If you have a Theme attribute and a StylesheetTheme attribute for the Page directive, what is the difference between the two?
The StylesheetTheme attribute works the same as the Theme attribute. The difference is that the when attributes are set locally on the page within a particular control, the attributes are overridden by the theme if you use the Theme attribute. They are kept in place, however, if you apply the page’s theme using the StylesheetTheme attribute. Suppose you have a text box control like the following:
In this example, the ForeColor settings is overridden by the theme if you have applied theme using the Theme attribute in the Page directive. If, you applied the theme using the StylesheetTheme attribute in the Page directive, the ForeColor settings remain in place, even if they are explicitly defined in the theme.
