View Answer/Explanation:
d
Explanation:
KeyDown: Occurs when a key is pressed while focus is on this element. * It occurs only once. * It occurs first in a keyboard event and is followed by the KeyPress event. * It is raised by noncharacter keys. * An event handler that handles this event receives KeyEventArgs as an argument type. KeyPress: * It occurs multiple times as long as a user holds a key. * It occurs later in a keyboard event and is succeeded by the KeyDown event. * It is not raised by noncharacter keys. * An event handler that handles this event receives KeyPressEventArgs as an argument type. Textchanged: Occurs when the text of the PropertyGrid changes. When the user changes the text of a Textbox, this event is not raised immediately. The form must contain a Command to initiate a postback event that raises the TextChanged event.
