Exemples

L’exemple de code suivant est une classe personnalisée ControlCollection qui remplace la ControlCollection méthode pour écrire des messages (qui incluent le nom de la Owner propriété) dans le journal des traces lorsqu’une instance de la collection est créée. Vous devez activer le suivi de la page ou de l’application pour que cet exemple fonctionne.

// Create a custom ControlCollection that writes
// information to the Trace log when an instance
// of the collection is created.
[AspNetHostingPermission(SecurityAction.Demand, Level=AspNetHostingPermissionLevel.Minimal)]
public class CustomControlCollection : ControlCollection
{
    private HttpContext context;

    public CustomControlCollection(Control owner)
        : base(owner)
    {

        HttpContext.Current.Trace.Write("The control collection is created.");
        // Display the Name of the control
        // that uses this collection when tracing is enabled.
        HttpContext.Current.Trace.Write("The owner is: " + this.Owner.ToString());
    }
}

' Create a custom ControlCollection that writes

<AspNetHostingPermission(SecurityAction.Demand, _
   Level:=AspNetHostingPermissionLevel.Minimal)> _
Public NotInheritable Class CustomControlCollection
    Inherits ControlCollection

    Private context As HttpContext

    Public Sub New(ByVal owner As Control)
        MyBase.New(owner)
        HttpContext.Current.Trace.Write("The control collection is created.")
        ' Display the Name of the control
        ' that uses this collection when tracing is enabled.
        HttpContext.Current.Trace.Write("The owner is: " _
