Repeater分页显示
简单的说，先从控件工具箱中拖入两个label（currten page当前页，count page总页），四个linkbuttion（首/下页/上页/尾页）。
无非就是+1 -1 的问题，

aspx文件:
<%@ Control Language="C#" AutoEventWireup="true" CodeFile="gonggao.ascx.cs" Inherits="gonggao" %>
<table>
<asp:Repeater ID="Repeater1" runat="server">
<ItemTemplate>
<tr><td><a href=""><%# cuts(DataBinder.Eval(Container.DataItem,"[标题]").ToString(),8)%></a></td>
<td><a href=""><%# cuts(DataBinder.Eval(Container.DataItem,"[时间]").ToString(),5)%></a></td></tr>
</ItemTemplate>
</asp:Repeater>
</table>
<table border="1"><tr><td align="center">
<asp:LinkButton ID="lbtnFirstPage" runat="server" OnClick="lbtnFirstPage_Click">页首</asp:LinkButton>
<asp:LinkButton ID="lbtnpritPage" runat="server" OnClick="lbtnpritPage_Click">上一页</asp:LinkButton>
<asp:LinkButton ID="lbtnNextPage" runat="server" OnClick="lbtnNextPage_Click">下一页</asp:LinkButton>
<asp:LinkButton ID="lbtnDownPage" runat="server" OnClick="lbtnDownPage_Click">页尾</asp:LinkButton><br />
第<asp:Label ID="labPage" runat="server" Text="Label"></asp:Label>页/共<asp:Label ID="LabCountPage" runat="server" Text="Label"></asp:Label>页 跳至<asp:DropDownList
ID="DropDownList1" runat="server">
</asp:DropDownList>
</td></tr>
</table>


附:pb.returnDs(根据SQL语句返回dataSet数据集.temptable表)
public DataSet returnDs(string sqlStr)
{

DataSet ds = new DataSet();
try
{
//conn.Open();
SqlCommand comm = new SqlCommand(sqlStr, conn);
comm.CommandTimeout = 20;
this.conn.Open();
SqlDataAdapter sda = new SqlDataAdapter(comm);
sda.Fill(ds, "temptable");
return ds;
conn.Close(); conn.Dispose(); comm.Dispose();

}
catch (Exception e)
{
throw (e);
// ds = null;
return ds;
}
finally
{
this.conn.Close();
}
