Repeater控件和DataList控件，可以用來一次顯示一組數據項。比如，可以用它們顯示一個數據表中的所有行。
Repeater控件完全由模板驅動，提供了最大的靈活性，可以任意設置它的輸出格式。DataList控件也由模板驅動，和Repeater不同的是，DataList默認輸出是HTML表格，DataList將數據源中的記錄輸出為HTML表格一個個的單元格 。
1、Repeater支持以下5種模板：
● ItemTemplate : 對每一個數據項進行格式設置 （包含要為數據源中每個數據項都要呈現一次的 HTML 元素和控件。）。
● AlternatingItemTemplate : 對交替數據項進行格式設置（包含要為數據源中每個數據項都要呈現一次的 HTML 元素和控件。）。
● SeparatorTemplate : 對分隔符進行格式設置（包含在每項之間呈現的元素。）。
● HeaderTemplate : 對頁眉進行格式設置（包含在列表的開始處分別呈現的文本和控件。）。
● FooterTemplate : 對頁腳進行格式設置（包含在列表的結束處分別呈現的文本和控件。）。
