Causes a control bound to the BindingSource to reread all the items in the list and refresh their displayed values.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
The method informs all controls bound to the BindingSource to refresh their values. The method does this by raising the ListChanged event at least once; the metaDataChanged parameter indicates the nature of the underlying change.
A metaDataChanged value of true indicates that the data schema of BindingSource has changed. A ListChanged event is raised with ListChangedEventArgs.ListChangedType set to ListChangedType.PropertyDescriptorChanged.
A metaDataChanged value of false indicates that only the values of one or more items have changed.
Regardless of the value of metaDataChanged, a ListChanged event is raised with ListChangedEventArgs.ListChangedType set to ListChangedType.Reset. As a consequence, calling with a parameter of true will raise two ListChanged events.
is automatically called whenever another member makes major changes to the data-binding, such as setting the DataSource or DataMember properties. However, the programmer can also call this method explicitly.
The following code example uses a BindingSource component to bind an array list, which does not provide change notification. An item is removed from the list, and the bound controls are notified of the change by calling the method. This code example is part of a larger example provided in How to: Reflect Data Source Updates in a Windows Forms Control with the BindingSource.
