Examples

The following code example demonstrates the use of this member. In the example, an event handler reports on the occurrence of the Control.Paint event. This report helps you to learn when the event occurs and can assist you in debugging.

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.Paint event.

Visual Basic

Private Sub Control1_Paint(sender as Object, e as PaintEventArgs) _ 
     Handles Control1.Paint

    Dim messageBoxVB as New System.Text.StringBuilder()
    messageBoxVB.AppendFormat("{0} = {1}", "ClipRectangle", e.ClipRectangle)
    messageBoxVB.AppendLine()
    messageBoxVB.AppendFormat("{0} = {1}", "Graphics", e.Graphics)
    messageBoxVB.AppendLine()
    MessageBox.Show(messageBoxVB.ToString(),"Paint Event")

End Sub


C#

private void Control1_Paint(Object sender, PaintEventArgs e) {

System.Text.StringBuilder messageBoxCS = new System.Text.StringBuilder();
messageBoxCS.AppendFormat("{0} = {1}", "ClipRectangle", e.ClipRectangle );
messageBoxCS.AppendLine();
messageBoxCS.AppendFormat("{0} = {1}", "Graphics", e.Graphics );
messageBoxCS.AppendLine();
MessageBox.Show(messageBoxCS.ToString(), "Paint Event" );
}

Example Content
The example works as given. Did you create a control and use that control's name property to the left of the paint event's underscore in your version of the example? The messagebox you have crafted should display with an OK button control. Click the OK button and you will see your control.

Terrible example code
The example code given here is one of the worst I've ever seen.
