GridView分页

public void gridviewbind()
    {


        DataTable CustmTable = GridGetSql("select * from EasAgeutInfo order by AgCode desc");

        for (int i = CustmTable.Rows.Count; i < 14; i++)
        {
            DataRow TableRow = CustmTable.NewRow();
            TableRow[0] = DBNull.Value;
            CustmTable.Rows.Add(TableRow);
        }

        this.GridView2.DataSource = CustmTable;
        this.GridView2.DataBind();
    }
    //载入页面时的方法
    public DataTable GridGetSql(string SqlStr)
    {
        SqlCommand SqlCmd = new SqlCommand();
        SqlCmd.Connection = new SqlConnection(strconn);
        SqlCmd.CommandText = SqlStr;
        SqlCmd.CommandType = CommandType.Text;
        SqlDataAdapter SqlAd = new SqlDataAdapter(SqlCmd);
        DataSet Rs = new DataSet();
        Rs.Clear();
        SqlAd.Fill(Rs);
        return Rs.Tables[0];
    }
 //分页
    protected void GridView2_PageIndexChanging(object sender, GridViewPageEventArgs e)
    {
       
        
      
        //if(GridView2.PageIndex>=0 || GridView2.PageIndex<GridView2.PageCount)
        //{
            GridView2.PageIndex = e.NewPageIndex;
           // GridView2.DataBind();
            this.gridviewbind();
       // }
        
         

    }
当我单击第二页的时候就没有那么多页了,这是怎么回事. --------------------编程问答-------------------- if(GridView2.PageIndex> =0   ¦ ¦   GridView2.PageIndex <GridView2.PageCount) 
这个不需要啊 --------------------编程问答--------------------   public   DataTable   GridGetSql(string   SqlStr) 
        { 
                SqlCommand   SqlCmd   =   new   SqlCommand(); 
                SqlConnection con =new   SqlConnection(strconn); －－－变化加了这个
                SqlCmd.Connection   =    con;      －－－－－－－－－－－变成这样   
                SqlCmd.CommandText   =   SqlStr; 
                SqlCmd.CommandType   =   CommandType.Text; 
                SqlDataAdapter   SqlAd   =   new   SqlDataAdapter(SqlCmd); 
                DataSet   Rs   =   new   DataSet(); 
                Rs.Clear(); 
                SqlAd.Fill(Rs); 
                con.close();------加上这个
                return   Rs.Tables[0]; 
        }
