列表視圖不顯示當最後一個記錄刪除使用asp.net

Question

我有一個列表視圖與刪除網格說我有一個頁面上的分頁鏈接（前1 2下一個）。當我試圖刪除第二頁中的最後一條記錄時，listview不會顯示出來。我已經在服務器端進行了綁定，並在記錄刪除時調用。如果第二頁有兩個以上的記錄，則表示網格。任何人都知道爲什麼會出現這個問題？但是當我重新加載網頁顯示。

我有一個列表視圖網格，

<asp:ListView ID="lvSurvey" runat="server" GroupPlaceholderID="groupPlaceHolder2" 
ItemPlaceholderID="itemPlaceHolder2" OnPagePropertiesChanging="OnPagePropertiesChangingSurvey" OnItemCommand="lvSurvey_ItemCommand" > 

--- 
-- 
</asp:ListView> 

我也有分頁作爲

<asp:PlaceHolder runat="server" ID="groupPlaceHolder2"></asp:PlaceHolder> 
     <tr> 
      <td colspan = "3"> 
       <asp:DataPager ID="DataPager2" runat="server" PagedControlID="lvSurvey" PageSize="1"> 
        <Fields> 
         <asp:NextPreviousPagerField ButtonType="Link" ShowFirstPageButton="false" ShowPreviousPageButton="true" 
          ShowNextPageButton="false" /> 
         <asp:NumericPagerField ButtonType="Link" /> 
         <asp:NextPreviousPagerField ButtonType="Link" ShowNextPageButton="true" ShowLastPageButton="false" ShowPreviousPageButton = "false" /> 
        </Fields> 
       </asp:DataPager> 
      </td> 
     </tr> 

我能夠在頁面中顯示從SQL Server記錄並分頁顯示。我在網格中的刪除按鈕

<asp:LinkButton ID="lnkDelete" runat="server" CssClass="btn btn-danger" OnClientClick="return getConfirmation(this, 'Please confirm','Are you sure you want to delete?');" CommandArgument='<%# Eval("Order_Survey_ID") + "|" + Eval("Status") %>' 
          CommandName="DeleteSurveyObject"><i class="glyphicon glyphicon-trash"></i>&nbsp;</asp:LinkButton>   <br /> 



      </td> 
     </tr> 


</ItemTemplate> 

    </asp:ListView> 

我也能刪除，也做服務器編碼deletion.But當只有一個第二路段記錄，不能夠在刪除時顯示列表視圖。

protected void OnPagePropertiesChanging(object sender, PagePropertiesChangingEventArgs e) 
    { 
     (lvOrderInstall.FindControl("DataPager1") as DataPager).SetPageProperties(e.StartRowIndex, e.MaximumRows, false); 
     this.GetAllOrderInstall(); 
     TabName.Value = "installation"; 

    } 

    protected void lvSurvey_ItemCommand(object source, ListViewCommandEventArgs e) 
     { 
if(e.CommandName == "DeleteObject") 
      { 
       string[] param = e.CommandArgument.ToString().Split('|'); 
       hfInstallID.Value = param[0].ToString(); 

       DELETEINSTALL(int.Parse(hfInstallID.Value), clsCommon.gConstDTOMode_Delete, clsCommon.gConstActive_Status); 
       GetAllOrderInstall(); 

       TabName.Value = "installation"; 
       litMsg.Text = "Record deleted successfully"; 
      } 
     }

嘗試lvSurvey_ItemCommand函數的末尾添加GetAllOrderInstall();重新綁定更新用後的列表視圖。

protected void lvSurvey_ItemCommand(object source, ListViewCommandEventArgs e) 
      { 
       if(e.CommandName == "DeleteObject") 
       { 
        string[] param = e.CommandArgument.ToString().Split('|'); 
        hfInstallID.Value = param[0].ToString(); 

        DELETEINSTALL(int.Parse(hfInstallID.Value), clsCommon.gConstDTOMode_Delete, clsCommon.gConstActive_Status); 
        GetAllOrderInstall(); 

        TabName.Value = "installation"; 
        litMsg.Text = "Record deleted successfully"; 
       } 

       GetAllOrderInstall(); 
      }
