ToolStripItem.VisibleChanged ToolStripItem.VisibleChanged ToolStripItem.VisibleChanged ToolStripItem.VisibleChanged Event

Definition

Occurs when the value of the Visible property changes.

public:
 event EventHandler ^ VisibleChanged;
public event EventHandler VisibleChanged;
member this.VisibleChanged : EventHandler 
Public Custom Event VisibleChanged As EventHandler 

Examples

The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the VisibleChanged 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 VisibleChanged event.

private void ToolStripItem1_VisibleChanged(Object sender, EventArgs e) {

   MessageBox.Show("You are in the ToolStripItem.VisibleChanged event.");

}
Private Sub ToolStripItem1_VisibleChanged(sender as Object, e as EventArgs) _ 
     Handles ToolStripItem1.VisibleChanged

   MessageBox.Show("You are in the ToolStripItem.VisibleChanged event.")

End Sub

Note

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