asp.net repeater控件操作

Repeater控件和DataList控件,可以用来一次显示一组数据项。比如,可以用它们显示一个数据表中的所有行。   Repeater控件完全由模板驱动,提供了最大的灵活性,可以任意设置它的输出格式。   DataList控件也由模板驱动,和Repeater不同的是,DataList默认输出是HTML表格,DataList将数据源中的记录输出为HTML表格一个个的单元格。

Repeater支持以下5种模板       ● ItemTemplate : 对每一个数据项进行格式设置 (必须的添加项)       ● AlternatingItemTemplate : 对交替数据项进行格式设置       ● SeparatorTemplate : 对分隔符进行格式设置       ● HeaderTemplate : 对页眉进行格式设置       ● FooterTemplate : 对页脚进行格式设置

 Repeater控件有以下事件:       ● DataBinding : Repeater控件绑定到数据源时触发       ● ItemCommand : Repeater控件中的子控件触发事件时触发       ● ItemCreated : 创建Repeater每个项目时触发       ● ItemDataBound : Repeater控件的每个项目绑定数据时触发

</asp:Repeater> repeater 绑定示例文件

同时需要在后台绑定repeater的数据源

  Container.ItemIndex为当前行的索引,从0开始

  style='background-color: <%#(Container.ItemIndex%2==0)?"#FFFFF;":"#fcf3f4"%>'  设置了repeater的隔行变色

  onmouseover="change_colorOver(this)" onmouseout="change_colorOut(this)" 设置了repeater的鼠标悬浮变色

js方法如下(colorName为页面中的一个隐藏的input标签,用于保存onmouseover时的颜色值)

<script>

  function change_colorOver(e) {       var oldColor = e.style.backgroundColor;       document.getElementById("colorName").value = oldColor;       e.style.backgroundColor = "#b9bace";   }   function change_colorOut(e) {       e.style.backgroundColor = document.getElementById("colorName").value;   }

</script>

} 后台代码

后台代码

后台: 启用外层Repeater的ItemDataBound事件 ,在ItemDataBound事件中找到内层的Repeater,并绑定内层的Repeater

前台: 外层的Repeater的ItemTemplate分为两行;第一行绑定一个数据表的数据信息,和添加一个显示控制按钮

    第二行中嵌入内层的Repeater(样式可以独立设置)

      然后在js文件中添加子菜单的显示和隐藏代码
