With controls come properties a set of variables that describe the appearance, behavior, and other aspects of the control , methods procedures built into a control that tell the control how to do things , and events actions that occur in your program. Properties, methods, and events common to most controls are described in the tables below. Every object, such as a form or control, has a set of properties that describe it. Although this set isn't identical for all objects, some properties such as those listed in the table below are common to most controls. You can see every design-time property for a given control by looking at the Properties window in the IDE some controls have properties that are available only at run-time — such as the SelectionStart and SelectionLength properties of the Textbox.
