戻り値

例

次の例では、サーバーコントロールを含むページがポストバックされたかどうかを確認します。The following example checks whether the page that contains the server controls has posted back. 存在する場合は、IsLiteralContent メソッドを呼び出して、コントロールにリテラルコンテンツだけが含まれているか、他のサーバーコントロールの親コントロールであるかを確認します。If it has, it calls the IsLiteralContent method to determine whether the control contains just literal content, or is a parent control to other server controls. 単にリテラルコンテンツが含まれている場合は、そのコンテンツを表す LiteralControl の UniqueID プロパティが応答に書き込まれます。If it contains solely literal content, the UniqueID property of the LiteralControl that represents that content is written to the response.

// Override the OnLoad method to check if the 
// page that uses this control has posted back.
// If so, check whether this controls contains
// only literal content, and if it does,
// it gets the UniqueID property and writes it
// to the page. Otherwise, it writes a message
// that the control contains more than literal content.
protected override void OnLoad(EventArgs e)
{
        if (Page.IsPostBack)
        {
                String s;

                if (this.IsLiteralContent())
                {
                        s = Controls[0].UniqueID;
                        Context.Response.Write(s);
                }
                else
                {
                        Context.Response.Write(
                                "The control contains more than literal content.");
                }
        }
}

' Override the OnLoad method to check if the 
' page that uses this control has posted back.
' If so, check whether this controls contains
' only literal content, and if it does,
' it gets the UniqueID property and writes it
' to the page. Otherwise, it writes a message
' that the control contains more than literal content.
Overrides Protected Sub OnLoad(ByVal e As EventArgs)

   If Page.IsPostBack = True Then
      Dim s As String

      If Me.IsLiteralContent() = True Then
         s = Controls(0).UniqueID
         Context.Response.Write(s)
      Else
         Context.Response.Write( _
         "The control contains more than literal content.")
      End If
   End If
End Sub

注釈

このメソッドが trueを返す場合、サーバーコントロールのコレクションは1つのリテラルコントロールを保持します。When this method returns true, the server control's collection holds a single literal control.
