BindingSource.CurrentChanged Event

Occurs when the currently bound item changes.

Namespace: System.Windows.Forms
Assembly: System.Windows.Forms (in system.windows.forms.dll)

public event EventHandler CurrentChanged
/** @event */
public void add_CurrentChanged (EventHandler value)

/** @event */
public void remove_CurrentChanged (EventHandler value)

In JScript, you can handle the events defined by a class, but you cannot define your own.
Not applicable.

The CurrentChanged event is raised whenever the Current property changes for any of the following reasons:

  • The current position of the List changes.

  • The DataSource or DataMember properties change.

  • The membership of the underlying List changes, which causes Position to refer to a different item. Examples include adding or deleting an item before the current item, deleting or moving the current item itself, or moving an item to the current position.

  • The underlying list is refreshed by a new sorting or filtering operation.

CurrentChanged is the default event for the BindingSource class.

For more information about handling events, see Consuming Events.

The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the CurrentChanged event. This report helps you to learn when the event occurs and can assist you in debugging. To report on multiple events or on events that occur frequently, consider replacing System.Windows.Forms.MessageBox.Show with System.Console.WriteLine or appending the message to a multiline TextBox.

To run the example code, paste it into a project that contains an instance of type BindingSource named BindingSource1. Then ensure that the event handler is associated with the CurrentChanged event.

private void BindingSource1_CurrentChanged(Object sender, EventArgs e) {

   MessageBox.Show("You are in the BindingSource.CurrentChanged event.");
