asp.net web application有master page

新增的page如果需要增加内容，需要使用asp:content

<asp:content id="Content1" contentplaceholderid="ContentPlaceHolder1" runat="Server">
        <script type="text/javascript">
            alert("Hello, World!");
        </script>
    </asp:content>

## the required attribute contentplaceholderid is not found on content control ##

在master page上有对应的，两边的id需要匹配上

<asp:ContentPlaceHolder ID="cphMain" runat="server">  
</asp:ContentPlaceHolder>

输入ContentPlaceHolderID之后，会自动提示master page上有哪几个place holder可以用
