Repeater控件

    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 。

1、Repeater支持以下5种模板：

      ● ItemTemplate : 对每一个数据项进行格式设置 （包含要为数据源中每个数据项都要呈现一次的 HTML 元素和控件。）。
      ● AlternatingItemTemplate : 对交替数据项进行格式设置（包含要为数据源中每个数据项都要呈现一次的 HTML 元素和控件。）。
      ● SeparatorTemplate : 对分隔符进行格式设置（包含在每项之间呈现的元素。）。
      ● HeaderTemplate : 对页眉进行格式设置（包含在列表的开始处分别呈现的文本和控件。）。
      ● FooterTemplate : 对页脚进行格式设置（包含在列表的结束处分别呈现的文本和控件。）。
