Gridview分页后SelectedIndexChanging怎么写
如题,我的SelectedIndexChanging中该怎么写好?网上找了不少就是对不上号…
后台代码如下
C# code

    protected void Page_Load(object sender, EventArgs e)
    {
            this.type = "格式二";
            this.sql = "select * from Hardware where " + this.Label1.Text.ToString().Trim() + " is not null or " + this.Label1.Text.ToString().Trim() + " <> ''";
            InforReport nrr = new MISOA.SQLServerDAL.InforReport(sql, type);
            GridView3.DataSource = nrr.GetDataSetByadminInfor();
            GridView3.DataBind();
}
    protected void GridView3_SelectedIndexChanging(object sender, GridViewSelectEventArgs e)
    {

    }


InforReport中 GetDatasetByadminInfor()如下:
C# code

        int i;
        public DataSet GetDataSetByadminInfor()
        {

            string sqlname = "select name from syscolumns where id=object_id('Hardware')";
            DataSet DB = SqlHelper.ExecuteReaderSelectToDataSet(SqlHelper.CreateConnection(), sqlname);
            DataSet DBds = SqlHelper.ExecuteReaderSelectToDataSet(SqlHelper.CreateConnection(), sql);
            DataSet ds = new DataSet();
            DataTable dt = new DataTable("VIEW");
            DataTable dt2 = new DataTable("Columns");
            ds.Tables.Add(dt);
            DataSet ds2 = new DataSet();
            ds2.Tables.Add(dt2);
            for (int k = 0; k < DB.Tables[0].Rows.Count; k++)
            {
                this.Name = DB.Tables[0].Rows[k][0].ToString().Trim();
                dt.Columns.Add(Name, typeof(string));
            }
            try
            {
                for (int j = 0; j < DBds.Tables[0].Rows.Count; j++)
                {
                    
                    DataRow dr = ds.Tables["VIEW"].NewRow();
                    for (i  = 0; i < DB.Tables[0].Rows.Count; i++)
                    {
                            Name = DB.Tables[0].Rows[i][0].ToString();
                            dr[Name] = DBds.Tables[0].Rows[j][i].ToString();
                        
                    }
                    ds.Tables["VIEW"].Rows.Add(dr);

                }
                return ds;
            }
            catch (Exception e2)
            {
                return ds;
            }
        }


Aspx代码如下:
C# code

<asp:GridView ID="GridView3" runat="server" EmptyDataText="无数据" Font-Size="Small" AllowPaging="True" OnSelectedIndexChanging="GridView3_SelectedIndexChanging">
   <PagerTemplate> 
<table width="100%"> 
                          <tr> 
                            <td style="text-align:right"> 
                            第 <asp:Label id="lblPageIndex" runat="server" text=' <%# ((GridView)Container.Parent.Parent).PageIndex + 1  %>' />页 
                                共/ <asp:Label id="lblPageCount" runat="server" text=' <%# ((GridView)Container.Parent.Parent).PageCount  %>' />页 
                                <asp:linkbutton id="btnFirst" runat="server" causesvalidation="False" commandargument="First" commandname="Page" text="首页" /> 
                              <asp:linkbutton id="btnPrev" runat="server" causesvalidation="False" commandargument="Prev" commandname="Page" text="上一页" />
