Appendix A. Useful Control Properties, Methods, and Events

A control interacts with a program or the user through properties, methods, and events. Although each type of control provides different features, they are all derived from the Control class. This class provides many useful properties, methods, and events that other controls inherit, if they don't take special action to override them. The following sections describe some of the most useful of these inherited features.

You can learn more about the Control class at msdn2.microsoft.com/library/system.windows.forms.control.aspx.

Properties

The following table lists properties implemented by the Control class. All controls that inherit from this class inherit these properties unless they override the Control class's behavior.

Property	Purpose
AllowDrop	Determines whether the control allows drag-and-drop operations.
Anchor	Determines which of the control's edges are anchored to the edges of the control's container.
AutoSize	Determines whether the control automatically resizes to fit its contents.
BackColor	Determines the control's background color.
BackgroundImage	Determines the control's background image.
BackgroundImageLayout	Determines how the control's background image is used to fill the control. This can be Center, None, Tile, Stretch, and Zoom.
Bottom	Returns the distance between the top edge of the control's container and the bottom edge of the control. This is read-only. Modify the Top and Height properties to change this value.
