Which of the following text box properties is used to determine whether the text box is bound,
unbound, or calculated?

A.
Name

B.
TextFormat

C.
Can Grow

D.
ControlSource

Explanation:
The ControlSource property is used to determine whether the text box is bound, unbound, or
calculated. The ControlSource property bounds a control to a field of a table. If a control is bound to
a field by using this property, the control is known as a bound control. If the value of this property is
blank, the control is known as an unbound control. If the ControlSource property contains an
expression, the control is known as a calculated control.
Answer C is incorrect. The Can Grow property allows a control to adjust its dimensions according to
the contents present in the control. A control grows vertically to adjust its contents so that all the
contents can be displayed. The default value of the Can Grow property is false.
Answer A is incorrect. The name property refers to the name given to a control in a form or a
report. The default name of the control is the control name plus 1, 2, 3, etc. The name of the control
should be meaningful so that it can be easily used during programming. The value of this property
cannot be changed programmatically. It can be changed only in design view.
Answer B is incorrect. The TextFormat property of a control helps to change a text to rich text
format. This helps to apply multiple formatting options for the text in a control. A user can change
the format of the text to bold, italics, etc., The user can also change the font of the selected text and
can apply other types of formatting.
