IE8表示,当使用动态占位符时,“无法显示网页”

我有一个ASP.NET使用占位符的页面。网格是以编程方式构建的,并在页面运行时添加到此占位符中。例子:

ASPX代码:

<asp:PlaceHolder ID="myPlaceHolder" runat="server" />

代码隐藏:

foreach (var country in Tables.Countries())
{
  var nGrid = BuildGrid(country.Code);
  if (nGrid.Rows.Count > 0)
  {
      var lTitle = new Literal();
      lTitle.Text = "<h2>Stats for country " + country.Name + "</h2>";

      myPlaceHolder.Controls.Add(lTitle);
      myPlaceHolder.Controls.Add(nGrid);
  }
  nGrid.Dispose();
}

private GridView BuildGrid(short countryCode)
{
    GridView nGrid = new GridView();
    nGrid.ID = "gr_" + countryCode;
    nGrid.SkinID = "rpSkin";
    nGrid.AutoGenerateColumns = false;
    nGrid.AllowPaging = false;
    nGrid.AllowSorting = false;
    nGrid.RowStyle.VerticalAlign = VerticalAlign.Top;
    nGrid.EnableViewState = false;

    var nField = new BoundField
                                 {
                                     HeaderText = "People",
                                     DataField = "PeopleCount"
                                 };
                nGrid.Columns.Add(nField);

    // more BoundFields of this type exist

    // This is basically the GridViewHelper class that gets Row Totals
    // Disabling this doesn't help, either
    HelpGrid(nGrid);
    nGrid.DataSource = Country.GetPeople(countryCode);
    nGrid.DataBind();
    return nGrid;
}

有什么想法吗?
