UserControl personalisé et evennements

J'ai un petit problème sur un de mes composant perso.
J'ai développé une sorte de smart tag gnre le smart trag de word.

en gros:

Code:

---

1 2 3 4

<cc1:SmartTag ID="smtg" runat="server"> <cc1:SmartTagItem id="smtgi1" runat="server" ImageUrl="..." /> </cc1:SmartTag>

---

Mon smart tag implemente un objet SmartTagCollection. Donc j'ai pas de problème pour ca.
Par contre, j'aimerai que mon objet smart tag ecoute les evenement de click sur mes smart tag item.

J'ai donc dans un SmartTagItem un champ privé ImageButton.

Code:

---

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20

public class SmartTagItem : IButtonControl { . . . private ImageButton img;   protected override RenderControl(Ht...) { img.ImageUrl = this.ImageUrl; img.Click += img_Click;   img.GetRenderControl(output); }   private void img_Click(....) ... }

---

Donc le pb est que je ne passe jamais dans la méthode Click (et pourtant j'ai bien un retour serveur du au render de mon bouton).

Si quelqu'un à une idée!! Je suis preneur.

A quel moment ajoutes tu le imageButton sur ton contrôle ?

En fait, lors du render de mon SmartTag, je fais appel au render de chaque SmartTagItem. Et c'est à ce moment la que je fais appel au ImageButton.

Je peux donner le code de mes deux objet si vous le souhaitez, mais je pense avoir donné l'essentiel.

Voici le code complet de mes objets

Code:
