Repeater分页，需要依靠PagedDataSource。这个类存在于System.Web.UI.WebControls命名空间。它的作用是作为数据源与数据显示控件的中间介质。
前台代码:
<body>
<asp:Repeater ID="Repeater1" runat="server">
<HeaderTemplate>
<p style="background-color:#988c6e;width:400px;padding-top:5px;padding-bottom:5px;margin-left:30px;margin-top:30px;border-radius:5px;color:#fff;font-weight:bold;"><span style="padding-left:30px;">用户名</span><span style="padding-left:100px;">注册时间</span><span style="padding-left:90px;">访问量</span></p>
<table style="margin-left:30px;margin-top:30px;">
</HeaderTemplate>
<ItemTemplate>
<tr>
<td style="width:120px;text-align:left; padding-left:20px;"><%#Eval("Username") %></td>
<td style="width:170px;text-align:left; "><%#Eval("RegistrationTime") %></td>
<td style="width:50px;text-align:left; "><%#Eval("AccessAmount") %></td>
</tr>
<tr>
<td colspan="3" style="border-bottom:1px inset #C0D9D9;padding-top:7px;"></td>
</tr>
</ItemTemplate>
<FooterTemplate>
</table>
</FooterTemplate>
</asp:Repeater>
<div style="margin-left:50px;">
<div style="margin:0 auto; margin-top:50px;border:1px solid #fff;font-size:16px;font-family:"microsoft yahei","宋体";">
<a><div style="border:1px solid #000; width:60px; float:left; margin:5px;text-align:center;"><a style="color:#000">共<asp:Label runat ="server" ID="zong"> </asp:Label>页</a></div></a>
<a><div style="border:1px solid #000; width:60px; float:left;margin:5px;text-align:center;"><a style="color:#000">第<asp:Label runat ="server" ID="dangqian"> </asp:Label>页</a></div></a>
<a><div style="border:1px solid #000; width:40px; float:left;margin:5px;text-align:center;"> <a style="color:#000"><asp:hyperlink id="first" runat="server" style="color:#000">首页</asp:hyperlink></a></div></a>
<a><div style="border:1px solid #000; width:60px; float:left;margin:5px;text-align:center;"><a style="color:#000"><asp:hyperlink id="lnkPrev" runat="server" style="color:#000">上一页</asp:hyperlink></a></div></a>
<a><div style="border:1px solid #000; width:60px; float:left;margin:5px;text-align:center;"><a style="color:#000"><asp:hyperlink id="lnkNext" runat="server" style="color:#000">下一页</asp:hyperlink></a></div></a>
<a><div style="border:1px solid #000; width:40px; float:left;margin:5px;text-align:center;"> <a style="color:#000"><asp:hyperlink id="end" runat="server" style="color:#000">尾页</asp:hyperlink></a></div></a>
</div>
</div>
</body>
后台代码：
protected void Page_Load(object sender, EventArgs e)
{
if(!Page.IsPostBack)
{
getUsers();
}
}
private void getUsers()
{
List<Users1> list = new AdminManager().QueryUsers();
PagedDataSource pag = new PagedDataSource();
pag.AllowPaging = true;// 设置允许分页
pag.PageSize = 10; // 每页显示为3行
pag.DataSource = list; // 模板绑定数据源
zong.Text = pag.PageCount.ToString(); // 显示总共页数
int CurrentPage;
// 请求页码为不为null设置当前页，否则为第一页
if (Request.QueryString["Page"] != null)
{
CurrentPage = Convert.ToInt32(Request.QueryString["Page"]);
}
else
{
CurrentPage = 1;
}
if (Request.QueryString["PageSize"] != null)
{
pag.PageSize = Convert.ToInt32(Request.QueryString["PageSize"]);
}
else
{
pag.PageSize = 10;
}
pag.CurrentPageIndex = CurrentPage - 1; // 当前页所引为页码-1
dangqian.Text = CurrentPage.ToString(); // 当前页
if (!pag.IsFirstPage)
{
// Request.CurrentExecutionFilePath为当前请求虚拟路径
lnkPrev.NavigateUrl = Request.CurrentExecutionFilePath + "?Page=" + Convert.ToString(CurrentPage - 1);
}
// 如果不是最后一页，通过参数Page设置下一页为当前页+1，否则不显示连接
if (!pag.IsLastPage)
{
// Request.CurrentExecutionFilePath为当前请求虚拟路径
lnkNext.NavigateUrl = Request.CurrentExecutionFilePath + "?Page=" + Convert.ToString(CurrentPage + 1);
}
//首页
first.NavigateUrl = Request.CurrentExecutionFilePath + "?Page=" + Convert.ToString(1);
//尾页
end.NavigateUrl = Request.CurrentExecutionFilePath + "?page=" + pag.PageCount.ToString();
if (Convert.ToInt32(HttpContext.Current.Request["page"]) > pag.PageCount)
{
first.NavigateUrl = Request.CurrentExecutionFilePath + "?Page=" + Convert.ToString(1);
}
this.Repeater1.DataSource = pag;
this.Repeater1.DataBind();
}
如果不需要进行分页,可执行以下代码:
protected void Page_Load(object sender, EventArgs e)
{
if(!Page.IsPostBack)
{
getUsers();
}
}
private void getUsers()
{
List<Users1> list = new AdminManager().QueryUsers();
this.Repeater1.DataSource = list ;
this.Repeater1.DataBind();
}
