What is a label control? What are two requirements for the text contained in a label control? Should a label control's identifying key include an access key? Why or why not?
What will be an ideal response?
A label control is used in an interface to display text that the user is not allowed to edit during run time, such as text that identifies other controls and text that represents the results of a calculation. The text contained in a label control that identifies another control's contents should be meaningful and left-aligned within the label. Users cannot access label controls, so it is inappropriate to include an access key in their identifying labels.
