Dynamic Actions in the Help Desk Ap-
plication
Dynamic actions are all about making your application's user interface easier for the
user. In the following exercises, you implement increasingly complex dynamic actions
to make the interface of your application more robust.
Starting Simple
In the first exercise you edit the Contact Us form on page 3 of the Help Desk applica-
tion. Although there is nothing wrong with the form as it stands, you've been asked to
limit input into the Body textarea until the user has entered something into the From e-
mail address field.
To create a dynamic action to do this, follow these steps:
1.
Edit
Page 3
of your application.
2.
Right-click the
P3_FROM
item and choose

from
the context menu. Using the menu shown in
Figure 16-1

way to create a dynamic action.
