Control.SystemColorsChanged Event

Definition

Occurs when the system colors change.

public event EventHandler SystemColorsChanged;
public event EventHandler? SystemColorsChanged;

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 SystemColorsChanged 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 Control, such as a Button or ComboBox. Then name the instance Control1 and ensure that the event handler is associated with the SystemColorsChanged event.

private void Control1_SystemColorsChanged(Object sender, EventArgs e) {

   MessageBox.Show("You are in the Control.SystemColorsChanged event.");
}

Remarks

This event is raised if the SystemColors is changed by either a programmatic modification or user interaction.
