　　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= width= % border= ＞＜TR＞＜td bgColor= #c c ＞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= % PageSize= AllowPaging= True AutoGenerateColumns= False DataKeyField= FDictid ＞＜SelectedItemStyle BackColor= #FFC ＞＜/SelectedItemStyle＞＜HeaderStyle BackColor= #C C ＞＜/HeaderStyle＞＜Columns＞＜asp:ButtonColumn Text= 选择 HeaderText= 选择 CommandName= Select ＞＜HeaderStyle Font Bold= True HorizontalAlign= Center Width= % ＞＜/HeaderStyle＞＜ItemStyle Font Bold= True HorizontalAlign= Center ＞＜/ItemStyle＞＜/asp:ButtonColumn＞＜asp:BoundColumn DataField= FDictID SortExpression= FDictID asc HeaderText= 标识号＞＜HeaderStyle Width= % ＞＜/HeaderStyle＞＜/asp:BoundColumn＞＜asp:BoundColumn DataField= FNameCn SortExpression= FNameCn asc HeaderText= 名称＞＜HeaderStyle Width= % ＞＜/HeaderStyle＞＜/asp:BoundColumn＞＜asp:BoundColumn DataField= FNameEn SortExpression= FNameEn asc HeaderText= 英文名称＞＜HeaderStyle Width= % ＞＜/HeaderStyle＞＜/asp:BoundColumn＞＜asp:BoundColumn DataField= FNote SortExpression= FNote asc HeaderText= 描叙＞＜HeaderStyle Width= % ＞＜/HeaderStyle＞＜/asp:BoundColumn＞＜/Columns＞＜PagerStyle Visible= False ＞＜/PagerStyle＞＜/asp:datagrid＞＜/td＞＜/tr＞＜/TABLE＞＜TABLE style= BORDER COLLAPSE: collapse cellSpacing= width= % bgColor= #ff border= ＞＜TR＞＜td align= right ＞＜asp:linkbutton id= btnFirst runat= server CommandArgument= fist ＞首页＜/asp:linkbutton＞  ＜asp:linkbutton id= btnPrev runat= server Width= px 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= px CssClass= textbox ＞＜/asp:TextBox＞＜asp:Button id= btnGo runat= server Text= GO CssClass= button Width= px ＞＜/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 ))MyDataGrid CurrentPageIndex ++;break;case ( prev ):if (MyDataGrid CurrentPageIndex ＞ )MyDataGrid CurrentPageIndex ;break;case ( fist ):MyDataGrid CurrentPageIndex= ;break;case ( last ):MyDataGrid CurrentPageIndex = (MyDataGrid PageCount );break;default://本页值MyDataGrid CurrentPageIndex = Convert ToInt (arg);break;BindGrid();

void ShowStatsPage()//显示页面信息lblCurrentIndex Text = [＜font color= blue ＞当前为第 + ((int)MyDataGrid CurrentPageIndex+ ) + 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();
