Ejemplos

En el ejemplo siguiente se comprueba si la página que contiene los controles de servidor se ha devuelto.The following example checks whether the page that contains the server controls has posted back. Si es así, llama IsLiteralContent al método para determinar si el control solo contiene contenido literal o si es un control primario de otros controles de servidor.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. Si contiene únicamente contenido literal, la UniqueID propiedad LiteralControl de que representa ese contenido se escribe en la respuesta.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

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
