C# “更新”面板中的“图像”按钮不工作

我使用更新面板中的图像按钮来显示图像。本地工作正常，但当我把它放在服务器上时，IE浏览器在点击图像按钮后无法显示图像

Firfox&chrome工作正常，但IE 10.0.11

   <asp:UpdatePanel ID="upBanners" UpdateMode="Always" runat="server">

本地所有浏览器工作正常，但服务器出现问题&仅IE不工作

提前谢谢

我已经解决了这个问题，将Imagebutton替换为LinkButton:）

  public void OnBannerOptionChanged(object sender, EventArgs e)
    {
        //Get the selected category and then the selected Language Values...
        string cat = this.ddlCategory.SelectedItem.Value;
        string lang = this.ddlLanguage.SelectedItem.Value;

        //Now cosntruct the directory structure...
        string dirStruct = "Banner/" + cat + "/" + lang;
        string dirStructPath = MapPath("~/" + dirStruct);
        if (Directory.Exists(dirStructPath))
        {
            BindBannerGrid(dirStruct);
            this.grdViewBanner.Visible = true;
        }
        else
        {
            this.grdViewBanner.Visible = false;
        }
    }

<asp:LinkButton ID="imgGO" runat="server" Text="Button" AlternateText="GO" ImageUrl="~/Images/button_go.gif" OnClick="OnBannerOptionChanged"><img src="/Images/button_go.gif" alt="" /></asp:LinkButton>
