AJAX popup control extender - comment mettre un bouton Annuler?

Question

Normalement, avec un extendeur de contrôle contextuel AJAX, il vous suffit de sélectionner l'élément et votre sélection remplira le contrôle associé. Cependant, si je veux remplir le contrôle directement ou par une liste déroulante, je voudrais avoir un bouton d'envoi et un bouton d'annulation. J'ai trouvé comment mettre un bouton Soumettre. Mais comment puis-je mettre un bouton d'annulation?

  <asp:TextBox runat="server" ID="txtWeek1MonAMTimeIn" Width="40px" /> 
      <cc1:PopupControlExtender 
       ID="PopupControlExtenderWeek1TimeIn" runat="server" 
       PopupControlID="pnlWeek1MonAMTimeIn" 
       Position="Bottom" 
       TargetControlID="txtWeek1MonAMTimeIn" 
       > 
      </cc1:PopupControlExtender>
