2.代码说明

1.翻页按钮

前台两个LinkButton（上一页、下一页），设置不同的CommandName、CommandArgument ，绑定同一个OnCommand事件，在后台OnCommand事件中分别处理

2.PagedDataSource

将原始数据转为 DataView 然后绑定到 PagedDataSource，通过 PagedDataSource 的内置属性实现分页和翻页，最后再绑定到 Repeater上面

2.Code

1.front end

<asp:Repeater ID="RptrReview" runat="server" OnItemCommand="RptrReview_ItemCommand" OnItemDataBound="RptrReview_ItemDataBound"  >
    ......  
</asp:Repeater>
<ul class="pager">
    <li class="previous"><asp:LinkButton ID="LnkBtnPrevious" runat="server" OnCommand="RepeaterPageChange_Command" CommandName="Previous" CommandArgument="-1" >&larr; 上一页</asp:LinkButton></li>
    <asp:Label ID="LblPageIndex" runat="server" Text="1" style="color:#428BCA;font-size:24px;"></asp:Label>
    <li class="next"><asp:LinkButton ID="LnkBtnNext" runat="server" OnCommand="RepeaterPageChange_Command" CommandName="Next" CommandArgument="1">下一页 &rarr;</asp:LinkButton></li>
</ul>

2.code-behind

protected void RepeaterPageChange_Command(object sender, CommandEventArgs e)
{
    PagedDataSource pds = new PagedDataSource(); 
    pds.DataSource=GetReviewDV();// 将DataView绑定到PagedDataSource上
    pds.AllowPaging = true; // 设置指示是否启用分页的值 
    pds.PageSize = 3; // 设置要在每页显示的数量 
    int pageIndex=Convert.ToInt32(LblPageIndex.Text.ToString())-1;
    pds.CurrentPageIndex = pageIndex;//获取 PagedDataSource当前页码
    if (e.CommandName=="Next"&&pds.IsLastPage)//已经是末页，还向下翻页的情况，跳过
    {
        RptrReview.DataSource = pds;
        RptrReview.DataBind();
    }
    else if (e.CommandName == "Previous"&&pds.IsFirstPage)//已经是首页，还向上翻页的情况，跳过
    {
        RptrReview.DataSource = pds;
        RptrReview.DataBind();
    }
    else//通过 e.CommandArgument 修改 PagedDataSource 页码
    {
        pageIndex = pageIndex + Convert.ToInt32(e.CommandArgument);
        LblPageIndex.Text = (pageIndex + 1).ToString();
        pds.CurrentPageIndex = pageIndex; // 设置当前页的索引。 
        RptrReview.DataSource = pds;
        RptrReview.DataBind();
    }
}

/// <summary>
/// 绑定RptrReview的第pageIndex页
/// </summary>
/// <param name="pageIndex"></param>
protected void BindRptrReview(ref int pageIndex)
{
    PagedDataSource pds = new PagedDataSource();
    pds.DataSource = GetReviewDV();
    pds.AllowPaging = true; // 设置指示是否启用分页的值 
    pds.PageSize = 3; // 设置要在每页显示的数量 
    //处理pageIndex极端情况
    if(pageIndex<0)
    {
        pageIndex=0;
    }
    else if(pageIndex>(pds.PageCount-1))
    {
        pageIndex=pds.PageCount-1;
    }
    pds.CurrentPageIndex = pageIndex; // 设置当前页的索引。 
    RptrReview.DataSource = pds;
    RptrReview.DataBind();
    
}
protected void RepeaterPageChange_Command(object sender, CommandEventArgs e)
{
    int pageIndex = Convert.ToInt32(LblPageIndex.Text.ToString()) - 1;
    pageIndex = pageIndex + Convert.ToInt32(e.CommandArgument);
    BindRptrReview(ref pageIndex);
    LblPageIndex.Text = (pageIndex + 1).ToString();
