How to: Navigate Data with the Windows Forms BindingNavigator Control
The advent of the BindingNavigator control in Windows Forms enables developers to provide end users with a simple data navigation and manipulation user interface on the forms they create.
The BindingNavigator control is a ToolStrip control with buttons preconfigured for navigation to the first, last, next, and previous record in a data set, as well as buttons to add and delete records. Adding buttons to the BindingNavigator control is easy, because it is a ToolStrip control. For more information, see How to: Add Load, Save, and Cancel Buttons to the Windows Forms BindingNavigator Control and How to: Add Load, Save, and Cancel Buttons to the Windows Forms BindingNavigator Control and How to: Add Load, Save, and Cancel Buttons to the Windows Forms BindingNavigator Control and How to: Add Load, Save, and Cancel Buttons to the Windows Forms BindingNavigator Control.
For each button on the BindingNavigator control, there is a corresponding member of the BindingSource component that programmatically allows the same functionality. For example, the MoveFirstItem button corresponds to the MoveFirst method of the BindingSource component, the DeleteItem button corresponds to the RemoveCurrent method, and so on. As a result, enabling the BindingNavigator control to navigate data records is a simple as setting its BindingSource property to the appropriate BindingSource component on the form.
To set up the BindingNavigator control
Add a BindingSource component named bindingSource1 and two TextBox controls named textBox1 and textBox2.
Bind bindingSource1 to data, and the textbox controls to bindingSource1. To do this, paste the following code into your form and call LoadData from the form's constructor or Load event-handling method.
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 Sub 'LoadDataprivate 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"); }Add a BindingNavigator control named bindingNavigator1 to your form.
Set the BindingSource property for bindingNavigator1 to bindingSource1. You can do this with the designer or in code.
bindingNavigator1.BindingSource = bindingSource1bindingNavigator1.BindingSource = bindingSource1;
