A.6.1.1.1. Exercise 1 solution

The ContentPlaceHolder element should be placed in the master page. It defines a region that content pages can fill in. The Content control should be placed in a content page that is based on the master page. It is used to supply the content for the ContentPlaceHolder element that it is connected to.

<asp:Button runat="server" SkinID="RedButton" CssClass="RedButton" />

The Button control in the ASPX page should then set the SkinID to RedButton:

<asp:Button ID="Button1" runat="server" Text="Button" SkinID="RedButton" />

<asp:Button ID="Button1" runat="server" EnableTheming="False" CssClass="RedButton"
