Comment : naviguer parmi les données avec le contrôle BindingNavigator Windows Forms
Le contrôle BindingNavigator dans Windows Forms permet aux développeurs de fournir aux utilisateurs finaux une interface utilisateur de navigation et de manipulation de données simple sur les formulaires qu'ils créent.
Le contrôle BindingNavigator est un contrôle ToolStrip avec des boutons préconfigurés pour la navigation vers quatre enregistrements (premier, dernier, suivant et précédent) dans un jeu de données, ainsi que des boutons pour ajouter et supprimer des enregistrements. L'ajout de boutons au contrôle BindingNavigator est facile, car il s'agit d'un contrôle ToolStrip. Pour obtenir des exemples, consultez How to : Add Load, Save and Cancel Buttons to the Windows Forms BindingNavigator Control.
Pour chaque bouton sur le contrôle BindingNavigator, il existe un membre correspondant du composant BindingSource qui active par programmation la même fonctionnalité. Par exemple, le bouton MoveFirstItem correspond à la méthode MoveFirst du composant BindingSource, le bouton DeleteItem correspond à la méthode RemoveCurrent, et ainsi de suite. Ainsi, pour activer le contrôle BindingNavigator pour parcourir des enregistrements de données, il suffit d'affecter à sa propriété BindingSource le composant BindingSource approprié sur le formulaire.
Pour configurer le contrôle BindingNavigator
Ajoutez un composant BindingSource nommé
bindingSource1et deux contrôles TextBox nomméstextBox1ettextBox2.Liez
bindingSource1aux données et les contrôles de zone de texte àbindingSource1. Pour cela, collez le code suivant dans votre formulaire et appelezLoadDataà partir de la méthode de gestion d'événements Load ou du constructeur du formulaire.private void LoadData() { // The xml to bind to. string xml = @"<US><states>" + @"<state><name>Washington</name><capital>Olympia</capital></state>" + @"<state><name>Oregon</name><capital>Salem</capital></state>" + @"<state><name>California</name><capital>Sacramento</capital></state>" + @"<state><name>Nevada</name><capital>Carson City</capital></state>" + @"</states></US>"; // Convert the xml string to bytes and load into a memory stream. byte[] xmlBytes = Encoding.UTF8.GetBytes(xml); MemoryStream stream = new MemoryStream(xmlBytes, false); // Create a DataSet and load the xml into it. DataSet set = new DataSet(); set.ReadXml(stream); // Set the DataSource to the DataSet, and the DataMember // to state. bindingSource1.DataSource = set; bindingSource1.DataMember = "state"; textBox1.DataBindings.Add("Text", bindingSource1, "name"); textBox2.DataBindings.Add("Text", bindingSource1, "capital"); }Private Sub LoadData() ' The xml to bind to. Dim xml As String = "<US><states>" + "<state><name>Washington</name><capital>Olympia</capital></state>" + "<state><name>Oregon</name><capital>Salem</capital></state>" + "<state><name>California</name><capital>Sacramento</capital></state>" + "<state><name>Nevada</name><capital>Carson City</capital></state>" + "</states></US>" ' Convert the xml string to bytes and load into a memory stream. Dim xmlBytes As Byte() = Encoding.UTF8.GetBytes(xml) Dim stream As New MemoryStream(xmlBytes, False) ' Create a DataSet and load the xml into it. Dim [set] As New DataSet() [set].ReadXml(stream) ' Set the DataSource to the DataSet, and the DataMember ' to state. bindingSource1.DataSource = [set] bindingSource1.DataMember = "state" textBox1.DataBindings.Add("Text", bindingSource1, "name") textBox2.DataBindings.Add("Text", bindingSource1, "capital") End SubAjoutez un contrôle BindingNavigator nommé
bindingNavigator1à votre formulaire.Définissez la propriété BindingSource pour
bindingNavigator1etbindingSource1. Vous pouvez la définir avec le concepteur ou dans le code.bindingNavigator1.BindingSource = bindingSource1;bindingNavigator1.BindingSource = bindingSource1
