Occurs when the Owner property changes.
public:
event EventHandler ^ OwnerChanged;public event EventHandler OwnerChanged;public event EventHandler? OwnerChanged;member this.OwnerChanged : EventHandler Public Custom Event OwnerChanged As EventHandler Event Type
Examples
The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the OwnerChanged 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 MessageBox.Show with 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 a type that inherits from ToolStripItem, such as a ToolStripButton or ToolStripMenuItem. Then name the instance ToolStripItem1 and ensure that the event handler is associated with the OwnerChanged event.
private void ToolStripItem1_OwnerChanged(Object sender, EventArgs e) {
MessageBox.Show("You are in the ToolStripItem.OwnerChanged event.");
}
Private Sub ToolStripItem1_OwnerChanged(sender as Object, e as EventArgs) _
Handles ToolStripItem1.OwnerChanged
MessageBox.Show("You are in the ToolStripItem.OwnerChanged event.")
End Sub
Remarks

Note
Changing the Enabled property of a ToolStrip does not raise the OwnerChanged event. Raise this event with specific property settings.
