Examples

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

private void Control1_Layout(Object sender, LayoutEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "AffectedComponent", e.AffectedComponent );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "AffectedControl", e.AffectedControl );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "AffectedProperty", e.AffectedProperty );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "Layout Event" );
}

Private Sub Control1_Layout(sender as Object, e as LayoutEventArgs) _ 
     Handles Control1.Layout

    Dim messageBoxVB as New System.Text.StringBuilder()
    messageBoxVB.AppendFormat("{0} = {1}", "AffectedComponent", e.AffectedComponent)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "AffectedControl", e.AffectedControl)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "AffectedProperty", e.AffectedProperty)
    messageBoxVB.AppendLine()
    MessageBox.Show(messageBoxVB.ToString(),"Layout Event")

End Sub
