Occurs when the value of the BackColor property changes.
public:
event EventHandler ^ BackColorChanged;public event EventHandler BackColorChanged;public event EventHandler? BackColorChanged;member this.BackColorChanged : EventHandler Public Custom Event BackColorChanged 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 BackColorChanged 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 BackColorChanged event.
private void ToolStripItem1_BackColorChanged(Object sender, EventArgs e) {
MessageBox.Show("You are in the ToolStripItem.BackColorChanged event.");
}
Private Sub ToolStripItem1_BackColorChanged(sender as Object, e as EventArgs) _
Handles ToolStripItem1.BackColorChanged
MessageBox.Show("You are in the ToolStripItem.BackColorChanged event.")
End Sub
Remarks
This event is raised if the BackColor property is changed by either a programmatic modification or user interaction.
Note
Changing the Enabled property of a ToolStrip does not raise the BackColorChanged event. Raise this event with specific property settings.
