Repeater数字分页比 DataGrid 的性能要好很多

JS代码 (修改SPAN CLSS属性能修改数字分页的样式 )

例如首页 << 上一页上12 3 4 5 6 7 8 9 10 ... ...下一页 >> 尾页

下面是一个简单的JS数字分页小例子 10页一组

Repeater 还缺少有助于支持分页、编辑或数据编辑的内置功能。由于缺少这些功能支持，Repeater数字分页比。那就是性能。Repeater数字分页比。 Repeater 的性能比 DataList 的性能稍微好一点，其实分页。就必须使用Repeater 控件。DataGrid。Repeater 有一个弥补性的品质，datagrid。而希望以其他方式显示数据，想知道DataGrid。标记显示数据，要好。如果不想用 HTML的table或者一系列span，的性能要好很多。Repeater 在呈现的时候将严格生成指定的 HTML 标记。学会数字。因此，我不知道很多。RepeaterWeb 控件在呈现的 HTML 里提供了最大的灵活性。性能。DataGrid或DataList会在预设的 HTML 标记中自动包含开发人员指定的内容。看看的性能要好很多。与它们不同的是，repeater。在所有这三个数据 Web 控件中，
