Notes

Le contrôle TreeView est utilisé pour afficher des données hiérarchiques, telles qu'une table des matières ou un répertoire des fichiers, dans une arborescence et prend en charge les fonctions suivantes :

  • Prise en charge de la liaison de données qui permet aux nœuds du contrôle d'être liés à des données XML, sous forme de tableau ou relationnelles.

  • Prise en charge de la navigation de site via une intégration avec le contrôle SiteMapDataSource.

  • Texte de nœud qui peut être affiché comme texte brut ou liens hypertexte.

  • Accès par programme au modèle objet TreeView pour créer des arborescences, remplir des nœuds, définir des propriétés, etc., de manière dynamique.

  • Remplissage de nœud côté client (sur les navigateurs pris en charge).

  • Possibilité d'afficher une case à cocher à côté de chaque nœud.

  • Possibilité de personnaliser l'apparence grâce à des thèmes, des images définies par l'utilisateur et des styles.

Pour plus d'informations sur le contrôle TreeView, consultez Vue d'ensemble du contrôle serveur Web TreeView.

Exemple

L'exemple de code suivant montre comment lier le contrôle TreeView à une source de données XML.

<asp:TreeView id="BookTreeView" dataSourceID="BookXmlDataSource" runat="server">
<DataBindings>
  <asp:TreeNodeBinding DataMember="Book" TextField="Title"/>
  <asp:TreeNodeBinding DataMember="Chapter" TextField="Heading"/>
  <asp:TreeNodeBinding DataMember="Section" TextField="Heading"/>
</DataBindings>
</asp:TreeView>

<asp:XmlDataSource id="BookXmlDataSource" runat="server">
  <Data>
    <Book Title="Book Title">
    <Chapter Heading="Chapter 1">
      <Section Heading="Section 1">
      </Section>
      <Section Heading="Section 2">
      </Section>
    </Chapter>
    <Chapter Heading="Chapter 2">
      <Section Heading="Section 1">
      </Section>
    </Chapter>
    </Book>
  </Data>
</asp:XmlDataSource>
<asp:TreeView id="BookTreeView" dataSourceID="BookXmlDataSource" runat="server">
<DataBindings>
  <asp:TreeNodeBinding DataMember="Book" TextField="Title"/>
  <asp:TreeNodeBinding DataMember="Chapter" TextField="Heading"/>
  <asp:TreeNodeBinding DataMember="Section" TextField="Heading"/>
</DataBindings>
</asp:TreeView>

<asp:XmlDataSource id="BookXmlDataSource" runat="server">

    <Book Title="Book Title">
    <Chapter Heading="Chapter 1">
      <Section Heading="Section 1">
      </Section>
      <Section Heading="Section 2">
      </Section>
    </Chapter>
    <Chapter Heading="Chapter 2">
      <Section Heading="Section 1">
      </Section>
    </Chapter>

</asp:XmlDataSource>
