Compatibilité dans un site Asp.Net 2.0

un projet Web Asp.Net 2.0.

Voir Figure 11 Après ajout de votre composant WebPart 2.0, la page Aspx du projet Asp.Net 2.0 doit contenir le composant de management de WebPart (WebPartManager) pour pouvoir utiliser les fonctionnalités d’édition de pages de composants WebParts ainsi que des zones de composants WebPart (WebPartZone) pour héberger le composant WebPart créé. Voici un exemple de code de page Aspx affichant :
 – un bouton (objet Button nommé btnDesign) permettant de passer en mode édition de page,
– 2 webpartZones (objets WebPartZone1 et WebPartZone2)
– 1 WebPartManager (objet WebPartManager1)
– le composant WebPart WPDemonstration créé précédemment

</html>

Ainsi que le Code Behind attaché permettant de basculer en mode édition de page :

using System;
using System.Data;
using System.Configuration;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;

public partial class _Default : System.Web.UI.Page
{
    protected void Page_Load(object sender, EventArgs e)
    {

    }
    protected void btnDesign_Click(object sender, EventArgs e)
    {
        WebPartManager1.DisplayMode = WebPartManager.DesignDisplayMode;
    }
}

Voici le résultat dans l’application Asp.Net 2.0, Voir Figure 12.
