Oracle Tips by Burleson |
Creating the Create Button
At this point, there is one button missing. The
missing button is the Create button that is used to navigate to the
application page where a form will allow the creation of new rows.
Since our own form has not been created yet, the Create button will be
added and it will navigate to application page two for now.
Navigate to the Page Definition page for the
Report, which is application page 11. If an application page is
running, click on the Edit Application link in the developer toolbar,
and then click on the Conference RSVP Report link in the Application
home page.
1.
From the Page Definition page, click on the  icon
in the Buttons region.
2.
On the Button Region, page click Next.
3.
On the Button Position page, choose the Create a button in a
region position option and click Next.
4.
On the Button Attributes page:
·
Button Name: CREATE
The [Create]
link can be used to do this.
·
Label: Create
·
Button Type: Template Driven
·
Action: choose the Redirect to URL without submitting
page option.
What this does
is prevent the creation of a separate Branch. Since the goal is to
get the Report page to redirect (navigate) to page two, and a branch
is not required, this option can be chosen. Even though a branch can
do the same thing, there is no need to have one. The maintenance of
the page components can be kept lower by not creating the branch.
·
Click Next.
5.
On the Image Attributes page leave the default and click Next.
6.
On the Display Properties page:
·
Position: Region Template Position #CREATE#
The [Create] link can be
used to do this.
·
Leave the rest default and click Next.
7.
On the Branching page:
·
Target: Page in this Application.
·
Page: 2
·
Request: leave blank
Leaving this option
blank will cause HTML DB to set the request to the Button Name
(CREATE). If the developer wanted to have a different request name,
it could be entered here. The request can be used in Conditional
Displayproperties to detect what
the request was set to when the page was submitted.
·
Clear Cache: 2
This clears the
session state for all page items on page two. All the page items will
be set to null. The cache for multiple pages can be cleared by
separating them by a comma.
·
There are no Conditional Display attributes that need to
be set for this button, so it is not necessary to go to the next
page. Click the Create Button button.
Run the report by clicking the  icon
in the upper right corner of the Page Definition page.
The finished report is shown in Figure 7.9. You
may ask yourself “Why would I want to build a report manually instead
of use the wizard?” Well, with more experience, developers usually
find that a wizard will not always do what is needed. The steps in
the previous lessons will give the experience needed to build your own
reports or modify those that have already been built using the wizard.
Later in this chapter there are other tips on how
to do even more with reports, but due to space constraints it is not
possible provide step-by-step instructions for all of them. The
experience gained so far will be valuable in knowing how to accomplish
those later lessons.
