{
    try
    {
        getsesiondata();
        LangID = 4;

        strRes = Ag.AVSearch_PropertyDetails(int.Parse(Request["Hid"].ToString()), dateArrival, dateDeparture, intPersons, int.Parse(drp_child.SelectedValue), intRooms, LangID, true, strRateFilter, "", strRateFilter, intMinRate, intMaxRate, strCurrency);
        GetData(strRes);
    }
    catch
    {

    }

}

我认为你应该先修改这些代码：

<强>之前

<ContentTemplate>
<asp:UpdatePanel/>

<强>后

</ContentTemplate>
</asp:UpdatePanel>

带有更新面板的Google地图未显示
