Gets or sets whether the user can input data into this element.
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
For FORM elements such as text boxes and radio buttons, setting to false will prevent the user from using these form fields. For other elements, such as DIV or SPAN, setting to false will cause all text within the element to appear shaded; however, the text will still be selectable. To cancel selection, add an event handler for the unexposed onselectstart event using the AttachEventHandler method.
