页面上直接引用
<%@ Register TagPrefix="scott" TagName="header" Src="Controls/Header.ascx" %>
<%@ Register TagPrefix="scott" TagName="footer" Src="Controls/Footer.ascx" %>
<%@ Register TagPrefix="ControlVendor" Assembly="ControlVendor" %>
<html>
<body>
<form id="form1" runat="server">
<scott:header ID="MyHeader" runat="server" />
</form>
</body>
</html>
配置文件引用(全局)
<?xml version="1.0"?>
<configuration>
<system.web>
<pages>
<controls>
<add tagPrefix="scottgu" src="~/Controls/Header.ascx" tagName="header"/>
<add tagPrefix="scottgu" src="~/Controls/Footer.ascx" tagName="footer"/>
<add tagPrefix="ControlVendor" assembly="ControlVendorAssembly"/>
</controls>
</pages>
</system.web>
</configuration>
当用户控件在同一个文件目录下的时候不能用配置文件引用,应该用"页面上直接引用".
