 2 默认的外观模板。以下外观仅作为示例提供。
 3 
 4 1. 命名的控件外观。SkinId 的定义应唯一，因为在同一主题中不允许一个控件类型有重复的 SkinId。
 5 
 6 <asp:GridView runat="server" SkinId="gridviewSkin" BackColor="White" >
 7    <AlternatingRowStyle BackColor="Blue" />
 8 </asp:GridView>
 9 
10 2. 默认外观。未定义 SkinId。在同一主题中每个控件类型只允许有一个默认的控件外观。
11 
12 <asp:Image runat="server" ImageUrl="~/images/image1.jpg" />
13 --%>
14 <asp:TextBox runat = "server" text = "这是主题1" BackColor="#c0c0c0" BorderColor = "#7f7f7f"
15     ForeColor = "#004400" Font-Size = "12pt" width = "150pt" />
16 <asp:TextBox SkinID = "TextBoxSkin" runat = "server" text = "这是主题11" BackColor = "red" 
17     BorderColor = "green" ForeColor = "yellow" Font-Size = "15pt" width = "150pt" />
