A
number of the standard field objects in the Object Library palette
support captions. Captions provide textual information to the viewers
about the form field.
When you add an object that supports captions, Designer assigns
a default name for the caption. The default name is the name of
the object. For example, if you add a list box object to the form
design, the default caption is List Box.
When creating the form design, you can see the caption for the
object in two places: on the form design next to the object (the
default position) or in the Field tab of the Object palette.
You can edit the caption text by using the Field tab of the Object
palette or by editing the caption text directly on the page. If
the text wraps as you type, increasing the size of the object will
display the text properly. If the object displays a white cross
in a red box 
, the
object either needs to be resized or have the caption reserve adjusted.
A reserve of 0 sets the caption area to auto-fit so that it adjusts
to fit the entire caption. The caption is protected and users cannot be
modified it when filling the form.
Note: When you bind a caption to a data source, the
caption is always shown in the form, even if you have set Caption
Position in the Layout tab to None.
If you need to rearrange field objects, but do not want to risk
modifying their captions, you can use the Lock Text command. Using
this command lets you to move the field objects around easily but
makes the caption not as easy to modify.
Note: You cannot select or edit captions if a field
object is locked. See
To lock objects.
You can dynamically populate a caption with a value
from a data source.
