需要改变Ext.net原生的蓝色主题。只需要在页面中添加。
<head runat="server">
<title>Ext.NET Examples - ExtJS ASP.NET Web Controls with AJAX</title>
<ext:ResourcePlaceHolder runat="server" Mode="Script" />
<ext:ResourcePlaceHolder runat="server" Mode="Style" />
<link rel="stylesheet" type="text/css" href="resources/css/main.css" />
<%--<cool:ScriptContainer ID="ScriptContainer1" runat="server" />--%>
<link href="E://TFS2008/Ext.Net/V1.0/ExtJS.Examples/resources/css/xtheme-pink.css" rel="stylesheet" type="text/css" />
<script type="text/javascript" src="resources/js/main.js"></script>
</head>

在head标签中加入需要引用主题的css文件地址。
