以上是我的Gridview表的代碼。目前我的問題是我的分揀工作不正常。但是，當它位於UpdatePanel之外時，它正在工作。Gridview排序不能在updatepanel中工作

protected void GridView7_Sorting(object sender, GridViewSortEventArgs e) 
    { 
     DataTable dtResult = (DataTable)ViewState["dt"]; 
     if (dtResult.Rows.Count > 0) 
     { 
      if (Convert.ToString(ViewState["Sort"]) == "Asc") 
      { 
       dtResult.DefaultView.Sort = e.SortExpression + " Desc"; 
       //ViewState["sort"] == "Desc"; 
      } 
      else 
      { 
       dtResult.DefaultView.Sort = e.SortExpression + " Asc"; 
       //ViewState["sort"] == "Asc"; 
      } 
      GridView7.DataSource = dtResult; 
      GridView7.DataBind(); 
     } 
    }

這是我的排序後面的代碼。任何幫助和建議將不勝感激。謝謝！

這是錯誤

嘗試增加'這樣AsyncPostBackTrigger'。 '的 <的ContentTemplate> 的 ' –

我按照你的建議嘗試了asyncpostbacktrigger，但它仍然沒有工作..任何其他建議？ –

您是否曾嘗試在'GridView7_Sorting（對象發件人，GridViewSortEventArgs e）'處保留斷點？它發射了嗎？ –

我相信你的錯誤將是這條線......

protected void GridView7Data_RowCommand(object sender, GridViewCommandEventArgs e) 
{ 
    int index = Convert.ToInt32(e.CommandArgument); // Error Converting 
}

按照上述評論你提到你的命令參數是「Name」不能轉換爲Integer ..

簡單的辦法讓你的rowIndex按下面的代碼

protected void gv_RowCommand(object sender, GridViewCommandEventArgs e) 
{ 
    if (e.CommandName == "xxx") 
    { 
     // Why LinkButton because your button type is LinkButton... 
     GridViewRow gvr = ((LinkButton)e.CommandSource).NamingContainer as LinkButton; 
     int rowIndex = gvr.RowIndex; 
    } 
}

參考爲LinkButton的作爲你的aspx HTML下面

<asp:LinkButton ID="lnkDownload7" runat="server" CommandArgument='<%# Eval("DetailsId") %>' 
OnClick="DownloadFile7" Text="Download"></asp:LinkButton>
