微软的DataPager分页功能很强大,不要设置数据库存储过程,只要添加个DataPager控件,关联下要分页的控件,简单设置就可以有不错的分页效果。当然要有更理想的效果还是要前台和后台处理下。

winform下的DataPager 显示模式:

浅谈VS中的DataPager分页

webForm下的样式由TemplatePagerField,NextPreviousPagerField和NumericPagerField控制

通过设置上面几个控件的配合也可以达到winForm下的效果,这3个控件中最重要的是TemplatePagerField控件。

下面简单看看TemplatePagerField控件可以怎么设置:

复制代码 代码如下:

    ByVal e As DataPagerCommandEventArgs)
    ' Check which button raised the event
    Select Case e.CommandName
      Case "Next"
        Dim newIndex As Integer = e.Item.Pager.StartRowIndex + e.Item.Pager.PageSize
        If newIndex <= e.TotalRowCount Then
          e.NewStartRowIndex = newIndex
          e.NewMaximumRows = e.Item.Pager.MaximumRows
        End If
      Case "Previous"
        e.NewStartRowIndex = e.Item.Pager.StartRowIndex - e.Item.Pager.PageSize
        e.NewMaximumRows = e.Item.Pager.MaximumRows
      Case "First"
        e.NewStartRowIndex = 0
        e.NewMaximumRows = e.Item.Pager.MaximumRows
    End Select
