先定义ASPX页面，注意AllowCustomPaging要设为False： body form id=DictList method=post runat=server TABLE style=BORDER-COLLAPSE: collapse cellSpacing=0 width=100% border=1 TR td bgColor=#c0c000信息：FONT face=Arial color=#ffffff数据维护/FONT

先定义ASPX页面，注意AllowCustomPaging要设为"False"：
<body>
<form id="DictList" method="post" runat="server">
<TABLE style="BORDER-COLLAPSE: collapse" cellSpacing="0" width="100%" border="1">
<TR>
<td bgColor="#c0c000">信息：<FONT face="Arial" color="#ffffff">数据维护</FONT>
</td>
</TR>
<tr>
<td><FONT face="宋体"></FONT></td>
</tr>
<tr>
<td><asp:datagrid id="MyDataGrid" runat="server" Width="100%" PageSize="20" AllowPaging="True" AutoGenerateColumns="False" DataKeyField="FDictid">
<SelectedItemStyle BackColor="#FFC080"></SelectedItemStyle>
<HeaderStyle BackColor="#C0C000"></HeaderStyle>
<Columns>
<asp:ButtonColumn Text="选择" HeaderText="选择" CommandName="Select">
<HeaderStyle Font-Bold="True" HorizontalAlign="Center" Width="8%"></HeaderStyle>
<ItemStyle Font-Bold="True" HorizontalAlign="Center"></ItemStyle>
</asp:ButtonColumn>
<asp:BoundColumn DataField="FDictID" SortExpression="FDictID asc" HeaderText="标识号">
<HeaderStyle Width="15%"></HeaderStyle>
</asp:BoundColumn>
<asp:BoundColumn DataField="FNameCn" SortExpression="FNameCn asc" HeaderText="名称">
<HeaderStyle Width="15%"></HeaderStyle>
</asp:BoundColumn>
<asp:BoundColumn DataField="FNameEn" SortExpression="FNameEn asc" HeaderText="英文名称">
<HeaderStyle Width="15%"></HeaderStyle>
</asp:BoundColumn>
<asp:BoundColumn DataField="FNote" SortExpression="FNote asc" HeaderText="描叙">
<HeaderStyle Width="47%"></HeaderStyle>
</asp:BoundColumn>
</Columns>
<PagerStyle Visible="False"></PagerStyle>
</asp:datagrid></td>
</tr>
</TABLE>
<TABLE style="BORDER-COLLAPSE: collapse" cellSpacing="0" width="100%" bgColor="#ff9966" border="1">
<TR>
<td align="right"><asp:linkbutton id="btnFirst" runat="server" CommandArgument="fist">首页</asp:linkbutton>  
<asp:linkbutton id="btnPrev" runat="server" Width="36px" CommandArgument="prev">上一页</asp:linkbutton>  
<asp:linkbutton id="btnNext" runat="server" CommandArgument="next">下一页</asp:linkbutton>  
<asp:linkbutton id="btnLast" runat="server" CommandArgument="last">末页</asp:linkbutton>  
<asp:label id="lblCurrentIndex" runat="server"></asp:label>/<asp:label id="lblPageCount" runat="server"></asp:label>  
跳转到<asp:TextBox id="txtGoPage" runat="server" Width="30px" CssClass="textbox"></asp:TextBox>
<asp:Button id="btnGo" runat="server" Text="GO" CssClass="button" Width="29px"></asp:Button></td>
</TR>
</TABLE>
</form>

codebehind主要功能部分代码：

private void Page_Load(object sender, System.EventArgs e)
{
// 在此处放置用户代码以初始化页面
myConnection = new SqlConnection(System.Configuration.ConfigurationSettings.AppSettings["ConnString"]);

if (!IsPostBack)
BindGrid();
}

public void BindGrid()
{
string strSql ="SELECT * FROM t_dict ";
SqlDataAdapter myCommand = new SqlDataAdapter(strSql, myConnection);
DataSet ds = new DataSet();
myCommand.Fill(ds, "t_dict");
MyDataGrid.DataSource=ds.Tables["t_dict"].DefaultView;
MyDataGrid.DataBind();
ShowStatsPage();
}

private void PagerButtonClick(object sender, System.EventArgs e)
{
//获得LinkButton的参数值
String arg = ((LinkButton)sender).CommandArgument;

switch(arg)
{
case ("next"):
if (MyDataGrid.CurrentPageIndex < (MyDataGrid.PageCount - 1))
MyDataGrid.CurrentPageIndex ++;
break;
case ("prev"):
if (MyDataGrid.CurrentPageIndex > 0)
MyDataGrid.CurrentPageIndex --;
break;
case ("fist"):
MyDataGrid.CurrentPageIndex=0;
break;
case ("last"):
MyDataGrid.CurrentPageIndex = (MyDataGrid.PageCount - 1);
break;
default:
//本页值
MyDataGrid.CurrentPageIndex = Convert.ToInt32(arg);
break;
}
BindGrid();
}

void ShowStatsPage()
{
//显示页面信息
lblCurrentIndex.Text = "[<font color="blue">当前为第：" + ((int)MyDataGrid.CurrentPageIndex+1) + "页</font>]";
lblPageCount.Text = "[<font color="blue">共：" + MyDataGrid.PageCount + "页</font>]";
}

private void MyDataGrid_PageIndexChanged(object source, System.Web.UI.WebControls.DataGridPageChangedEventArgs e)
{
//处理按下数字的方法
MyDataGrid.CurrentPageIndex = e.NewPageIndex;
BindGrid();
}

private void btnGo_Click(object sender, System.EventArgs e)
{
//页面直接跳转的代码
if(txtGoPage.Text.Trim()!="")
{
int PageI=Int32.Parse(txtGoPage.Text.Trim())-1;
if (PageI >=0 && PageI < (MyDataGrid.PageCount))
MyDataGrid.CurrentPageIndex = PageI ;
}
BindGrid();
}
//----------------------翻页代码结束
