このエラーに関する Infragistics と StackOverflow の投稿をすべて読んだと思いますが、問題を特定できませんでした。私は使用しています：

Infragistics4、v11.2 Visual Studio 2012 とその IIS DotNetNuke 6.1 3 レベルの階層グリッドがあります。最初のレベルを拡張するときは問題ありません。ここにいくつかのコードがあります

public void Page_Init(object sender, System.EventArgs e)
{
  this.reportGrid.RowIslandsPopulating += (s, arg) => reportGrid_RowIslandsPopulating(s, arg);
  this.reportGrid.PreRender += (s, arg) => reportGrid_PreRender(s, arg);
  this.reportGrid.InitializeRow += (s, arg) => reportGrid_InitializeRow(s, arg);
}

protected void Page_Load(object sender, System.EventArgs e)
{
   if (IsPostBack)
   {

     if (AppSettings.IsAjaxPostBack)
     {
       reportGrid.DataSource = report.Universities;
       reportGrid.DataBind();
     }
     else
    {
      DoSearch();
     }
} 

void reportGrid_RowIslandsPopulating(object sender, ContainerRowCancelEventArgs e)
{
  e.Cancel = true;
  switch (e.Row.Level)
  {
    case 0:
      BindSecondLevel(e);
      break;
    case 1:
      BindThirdLevel(e);
      break;
  }
}

void reportGrid_InitializeRow(object sender, RowEventArgs e)
{
  if (((ContainerGridRecord)e.Row).Level < 2)
     ((ContainerGridRecord)e.Row).IsEmptyParent = true;
}

private void BindSecondLevel(ContainerRowCancelEventArgs e)
{
  var child = new ContainerGrid();
  e.Row.RowIslands.Add(child);
  child.Level = 1;
  child.AutoGenerateColumns = false;
  child.DataKeyFields = "DisciplineID";
  child.Columns.Add(new BoundDataField(false) { Key = "DisciplineID", DataFieldName = "DisciplineID", Hidden = true });
  child.Columns.Add(new BoundDataField(false) { Key = "Name", DataFieldName = "Name" });
  child.ViewStateMode = System.Web.UI.ViewStateMode.Disabled;

  child.DataSource = someDisciplines;
  child.DataBind();
}

2 番目のレベルの展開ボタンをクリックすると、次のようにスローされます。

スクリプト ブロックの 22 行目、34 列目の未処理の例外

0x800a139e - Microsoft JScript ランタイム エラー: ASP.NET Ajax クライアント側フレームワークの読み込みに失敗しました

EDIT1: 第 2 レベルの行を展開すると AppSettings.IsAjaxPostBack は false に等しいが、第 1 レベルの行を展開すると true に等しいことがわかりました

EDIT2: web.config

EDIT3: 2 番目のレベルの拡張は、明確な Web サイトでも機能していません (つまり、DotNetNuke ではありません)。

問題が見つかりました。EnableViewState = False です。EnableViewState = False のときに第 1 レベルの拡張が機能しているのに、第 2 レベルが機能しない理由を自分で説明することはできません。
