Updating Objects in the Detail Display Group

In this section, you’ll add the ability to insert, update, and delete movie

roles. The MovieDetails page will then look something like this:

Many of the features in this page are similar to features in the Main page,

but in this section you perform by hand the tasks the wizard performed for

you to create Main. Already you’ve learned how to create a DisplayGroup

variable and how to bind it to dynamic elements. In this section you’ll:

• Write code to update a display group’s selected object.

• Create and conﬁgure a browser.

• Create a custom enterprise object class.

• Conﬁgure image buttons to insert, update, and delete using display

group actions.

Click a role to select it and display its

information in the editing part below.

Use the browser to choose an actor for the

selected role.

Click here to create a new, empty role.

Click here to delete the selected role.

Click here to save your work in the database

(add the new roles you inserted, remove the

roles you deleted, and save changes you made

to existing roles).

Edit the name of the selected role.
