(一) . 简要
AjaxPanel, 一个自定义控件, 只要在页面中将AjaxPanel作为父控件, 则它内部的控件在运行时无刷新.
做了个程序试了一下果然比较Cool ! 下面介绍一下具体配置, 配置也比较简单.
(二). 运行示例图
(三). 配置
1. 把 AjaxPanel 添加到工具箱中. 步骤如下:
2. 在Web.Config文件的: <configuration> 节,添加如下配置:
1 <configSections>
2 <section name="magicAjax" type="MagicAjax.Configuration.MagicAjaxSectionHandler, MagicAjax"/>
3 </configSections>
4 <magicAjax outputCompareMode="HashCode" tracing="false">
5 <pageStore mode="NoStore" unloadStoredPage="false" cacheTimeout="5" maxConcurrentPages="5" maxPagesLimitAlert="false"/>
6 </magicAjax>
7 <configSections>
2 <section name="magicAjax" type="MagicAjax.Configuration.MagicAjaxSectionHandler, MagicAjax"/>
3 </configSections>
4 <magicAjax outputCompareMode="HashCode" tracing="false">
5 <pageStore mode="NoStore" unloadStoredPage="false" cacheTimeout="5" maxConcurrentPages="5" maxPagesLimitAlert="false"/>
6 </magicAjax>
7 <configSections>
1 <system.web>
2 <httpModules>
3 <add name="MagicAjax" type="MagicAjax.MagicAjaxModule, MagicAjax"/>
4 </httpModules>
5 <system.web>
2 <httpModules>
3 <add name="MagicAjax" type="MagicAjax.MagicAjaxModule, MagicAjax"/>
4 </httpModules>
5 <system.web>
(四). 做了上面几步配置后, 下面就可以使用了, 示例代码也非常简单, 具体如下:
1.前台页面文件 Magicajax.aspx 代码如下:
1 <body>
2 <form id="form1" runat="server">
3 <div>
4 <ajax:AjaxPanel ID="AjaxPanel1" runat="server" Font-Bold="True">
