**my backend code is->**

    {
        addInventoryAllSelectDataSource.InsertParameters[0].DefaultValue = imeiText.Text;
        addInventoryAllSelectDataSource.InsertParameters[1].DefaultValue = carrierDropDown.SelectedValue;

        addInventoryAllSelectDataSource.InsertParameters[6].DefaultValue = smartphoneRadioList.SelectedValue;
        addInventoryAllSelectDataSource.InsertParameters[7].DefaultValue = transferOrderNoText.Text;
        addInventoryAllSelectDataSource.InsertParameters[8].DefaultValue = Session["user"].ToString();
        addInventoryAllSelectDataSource.Insert();
       // gridList.Add(new AddImei(imeiText,carrierDropDown.SelectedValue,(((int)d1[modelDropDown.SelectedIndex][0]).ToString())

        //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()));
        //AddImei ob1=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();
    }

问题是当我单击下一页时，它不会更改页面，我再次单击然后页面更改。转到下一页后，我点击上一页没有任何变化，我再次点击，然后我得到上述异常。我一直在寻找解决这个问题几个小时，无法弄清楚我在这里做错了什么。

您必须在 PageIndexChanged 事件之后调用填充 GridView1 的函数

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