A
choice subform set
is
a variation of the subform set object that allows you to customize
the display of specific subforms from within the set through the
use of conditional statements. As with subforms sets, choice subform
sets are bound to data from a data connection. However, using choice
subform sets provides a greater level of control over which subforms
within the set are displayed at run time. For example, you can configure
a choice subform set to display instances of a repeating subform
by using different text colors, depending on the value of a specific
field within that repeating subform.
To create choice subform sets
You can create a choice subform
set from either an existing subform set or from an existing subform
object.
To create a choice subform set from an existing subform set
-
Select a subform set object.
-
In the Object palette, click the Subform Set tab and select
the Select One Subform from Alternatives option from the Type list.
To create a choice subform set from a subform object
Select a subform object and select Insert > Wrap in Choice
Subform Set.
To add and remove subforms in choice subform sets
You can add subform
objects to a choice subform set or remove subform objects from a
choice subform set in using either of these methods:
-
Using the Edit Data Nominated Subforms dialog box
-
Manually editing the contents by dragging subform objects
into or out of the choice subform set by using the Hierarchy palette.
Important:
Removing a subform from the Alternative Subforms list by using the Edit Data Nominated Subforms dialog box completely removes the subform object from your form design. If you want to preserve the subform object but remove it from the choice subform set, you must manually drag the subform object out of the choice subform set by using the Hierarchy palette.
To add a subform to a choice subform set
-
Select a
subform set object.
-
In the Object palette, click the Subform Set tab and click
Edit Alternatives.
-
Click the Add button
to insert
a new Alternative Subforms list item. You can also drag and drop
subform objects into the choice subform set by using the Hierarchy
palette.
Adding a new subform adds a duplicate of the currently
selected subform. If no subform is selected, a new unnamed subform
is added to the choice subform set.
-
Use the Up
and
Down
buttons
to move the new subform entry to the preferred location. Ordering
entries in the Alternative Subforms list is important because entries
are processed sequentially at run time, and the first entry with
an expression that evaluates to
true
appears in
the form.
To remove a subform from a choice subform set
-
Select
a subform set object.
-
In the Object palette, click the Subform Set tab and click
Edit Alternatives.
-
Select an entry from the Alternative Subforms list and click
the Delete button
.
