  • GridView分页用法

    本人通过学习GridView,查看的相关资料,总结了实现上一页、下一页、首页、尾页、页面跳转的方法如下

    新建一个.aspx页面:

    <%@ Page Language="C#" AutoEventWireup="true" CodeFile="Sjy_Form.aspx.cs" Inherits="Sjy_Form" %>
    <%@ OutputCache Duration="2" VaryByParam="*" %>

    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
    <html xmlns="http://www.w3.org/1999/xhtml" >
    <head runat="server">
        <title>数据源管理窗口</title>
        <script language="javascript" src="Js/calendar.js" charset="gb2312"></script>
            <style>
                .c{
                       FILTER: alpha(style=1,opacity=0,finishOpacity=1,startX=1 , startY=1 , finishX=99, finishY=99 );
                }
                html{  
                  html { overflow-x:hidden; }  
                }  
            </style>
    </head>
    <body>
        <form id="form1" runat="server">

              <div id="b" style="left: 11px; overflow-x :auto; overflow-y:auto;
                645px; position: absolute; top: 419px; height: 195px">

                        </asp:BoundField>
                        <asp:BoundField DataField="sjymc" HeaderText="数据源名称" SortExpression="sjymc" >

                            <HeaderStyle HorizontalAlign="Left" />
                            <ItemStyle Wrap="False" />
                        </asp:BoundField>
                        <asp:BoundField DataField="jlr" HeaderText="建立人">
                            <HeaderStyle HorizontalAlign="Left" />
                        </asp:BoundField>
                        <asp:BoundField DataField="jlrq" HeaderText="建立日期" DataFormatString="{0:d}">
                            <HeaderStyle HorizontalAlign="Left" />

                        </asp:BoundField>
                    </Columns>
                    <PagerTemplate>
                        <table width="100%">

                                    共/<asp:Label ID="lblPageCount" runat="server" Text='<%# ((GridView)Container.Parent.Parent).PageCount  %>'></asp:Label>页
                                    <asp:LinkButton ID="btnFirst" runat="server" CausesValidation="False" CommandArgument="First"

                                </td>
                            </tr>
                        </table>

            </div>
        </form>
    </body>
    </html>

    后台代码:

    #region Gridview数据填充
        /// <summary>

        private void Gridview_Bind()

                else

                    linkBtnNext.Enabled = true;
                }

                for (int i = 0; i <= GridView1.Rows.Count - 1; i++)
                {

                    string gIntro;

                        gIntro = Convert.ToString(mydrv["sjysm"]);     //这里取出单元格数据,
                        GridView1.Rows[i].Cells[7].Text = SubStr(gIntro, 4);//自定义了一个函数SubStr进行截取,返回的值重新绑定到gridview控件的单元格中.
                    }
                    else
                    {

                    }
                }

        }
        #endregion

    如果大家有其它好的方法,希望能提出。
