Repeater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。
Repeater支持以下5种模板
● ItemTemplate : 对每一个数据项进行格式设置 【Formats each item from the data source.】
● 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 ,在加载开始执行一遍
● FooterTemplate : 对页脚进行格式设置,在加载最后执行一遍
以上,英文中使用了Formats item from datasource这样的话,就说明Repeater控件主要是用来对数据进行Format的,控制数据怎么样排列,怎么样显示。
Repeater必须使用的是Itemtemplate,其它的类型模板按需添加。

棒效果
意思是,当鼠标放上的时候,改变其属性,比如:背景色,边框颜色,边框样式等
方法:js代码实现,用到两个事件,分别是:onmouseover(鼠标放上)和onmouseout(鼠标离开)
1、不论是正常显示的还是预警显示的,当鼠标放上时,背景色变为黄色;鼠标离开,回复原来的颜色。
</style> <script > window.onload=function(){ var items = document.getElementsByClassName("tr_Item"); var oldColor = "";注释:存放原来的背景色 for (var i = 0; i < items.length; i++) { items[i].onmouseover = function () { oldColor = this.style.backgroundColor; this.style.backgroundColor = "yellow"; } items[i].onmouseout = function () { this.style.backgroundColor = oldColor; } } } </script> </head> <body>
2、除预警显示红色不变外,当鼠标放上时,背景色变为黄色;鼠标离开,回复原来的颜色。
</style> <script > window.onload=function(){ var items = document.getElementsByClassName("tr_Item"); for (var i = 0; i < items.length; i++) { if (items[i].style.backgroundColor != Red) { items[i].onmouseover = function () { this.style.backgroundColor = "yellow"; } items[i].onmouseout = function () { this.style.backgroundColor = oldColor; } } } } </script>
Repeater控件的事件处理
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
