The following code example demonstrates using the Reset Bindings method to notify a bound control about an update in the data source.

using namespace System; using namespace System:: Collections:: Generic; using namespace System:: Component Model; using namespace System:: Data; using namespace System:: Drawing; using namespace System:: Text; using namespace System:: Xml; using namespace System:: Windows:: Forms; using namespace System:: IO; namespace System_Windows_Forms_Update Binding int main() Imports System.

Text = "Form1" ' Create an Array List containing some of the State objects. When you use data-bound controls, you sometimes have to respond to changes in the data source when the data source does not raise list-changed events. Private label1 As Label Private label2 As Label Private text Box1 As Text Box Private text Box2 As Text Box Private With Events button1 As Button Private binding Source1 As Binding Source Private states As Array List Public Sub New() ' Basic form setup. When you use the Binding Source component to bind your data source to a Windows Forms control, you can notify the control that your data source has changed by calling the Reset Bindings method. Add("Text", binding Source1, "Capital") End Sub Private Sub button1_Click(By Val sender As Object, By Val e As Event Args) _ Handles button1. Run(New Form1()) End Sub ' The State class to add to the Array List.
