Modifying data
You can add, modify, or delete rows in the Preview view. When
you have finished manipulating the data, you can apply the changes
to the database.
Changing input language
You (and your users) can add or modify data in a DataWindow
object in multiple input languages. If you use multiple input languages,
you can display a Language bar on your desktop to change the current
input language. In a DataWindow object, the input language in effect
the first time a column gets focus becomes the default input language
for that column. If you subsequently change the input language when
that column has focus, the new input language becomes the default
for that column. This behavior does not apply to columns that have
the RightToLeft property set.
If looking at data from a view or from more than onetable
By default, you cannot update data in a DataWindow object that contains
a view or more than one table. For more about updating DataWindow objects, see Chapter 21, “Controlling Updates in DataWindow Objects.”
To modify existing data:
-
Tab to the field and enter a new value.
The Preview view uses validation rules, display formats, and
edit styles that you have defined for the columns, either in the
Database painter or in this particular DataWindow object.
To save the changes to the database, you must apply them,
as described next.
