**my backend code is->**

    { 
     addInventoryAllSelectDataSource.InsertParameters[0].DefaultValue = imeiText.Text; 
     addInventoryAllSelectDataSource.InsertParameters[1].DefaultValue = carrierDropDown.SelectedValue; 
     addInventoryAllSelectDataSource.InsertParameters[2].DefaultValue = ((int)d1[modelDropDown.SelectedIndex][0]).ToString(); 
     addInventoryAllSelectDataSource.InsertParameters[3].DefaultValue = costPriceText.Text;

     addInventoryAllSelectDataSource.InsertParameters[6].DefaultValue = smartphoneRadioList.SelectedValue;

     //GridView1.DataSource = gridList; 
     //GridView1.DataBind(); 
     //GridView1.DataSource = selectInventoryDataSource.Select(DataSourceSelectArguments.Empty); 
     //GridView1.DataBind(); 
     addInventoryAllSelectDataSource.SelectCommand = "SELECT A.IMEI,A.CARRIER, F.MAKE, F.MODEL, A.COST_PRICE,A.SELLING_PRICE,A.DATE,A.SMARTPHONE,A.TRANSFER_ORDER_NO,A.USER_ID FROM AddInventory AS A FULL OUTER JOIN "+carrierDropDown.SelectedValue+" AS F ON A.CARRIER_ID_INVENTORY = F.CARRIER_ID WHERE (A.IMEI = '"+imeiText.Text+"')"; 
     d3 = (DataView)addInventoryAllSelectDataSource.Select(DataSourceSelectArguments.Empty); 
     gridList.Add(new AddImei(d3[0][0].ToString(), d3[0][1].ToString(), d3[0][2].ToString(), d3[0][3].ToString(), Convert.ToDouble(d3[0][4]), Convert.ToDouble(d3[0][5]), Convert.ToDateTime(d3[0][6]).Date, Convert.ToBoolean(d3[0][7]), d3[0][8].ToString(), d3[0][9].ToString()));

     GridView1.DataSource = gridList; 
     GridView1.DataBind(); 
    } 

問題是，當我點擊下一頁，它不會改變頁面，我再次點擊，然後頁面更改。進入下一頁後，我點擊上一頁沒有任何變化，我再次點擊，然後我得到上述異常。我一直在尋找解決這個問題幾個小時，不能弄清楚我在這裏做錯了什麼。

你要調用補GridView1的PageIndexChanged事件

protected void changed(object sender, GridViewPageEventArgs e) 
{ 
    GridView1.PageIndex = e.NewPageIndex; 
    this.fillGridView1(); 
}
