This Control is the base class for the various button-like controls supported by the .NET Framework, including Button (a pushbutton), CheckBox, and RadioButton.

In addition to the standard control features, it provides support for an Image (which can then be positioned in the control using the ImageAlign property) and for alignment of the text (using the TextAlign property).

Note that the default FlatStyle for this class supports .NET features such as images, font, and color changes, but does not support Windows XP themes. You must set the FlatStyle to System in this case, but you will lose the .NET features.
