How to: Reflect Data Source Updates in a Windows Forms Control with the BindingSource

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. When you use the xref:System.Windows.Forms.BindingSource 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 xref:System.Windows.Forms.BindingSource.ResetBindings%2A method.

Example

The following code example demonstrates using the xref:System.Windows.Forms.BindingSource.ResetBindings%2A method to notify a bound control about an update in the data source.
