Is it possible to do in APEX?

Question

Hi everyone....i have the following scenario in my application...I will show you an example which resembles my scenario in my app..
Let's say.. i have 3 pages in a small application and i have navigation list with list template as (*Vertical Unordered List with Bullets*) on the page to navigate from one page to another.. like this..
                                                        PAGE1
                                                       ======
TABLE1
=======
                                  CREATE        CANCEL                                                                                                              
                                                                                                                    Navigation
                                                                                                                   ========
(Text Field) Last name:                                                                                 Page1 (link to goto page1)
(Text Field) First name:                                                                                 Page2 (link to goto page2)
(Text Field) Email:                                                                                        Page3 (link to goto page3)
                                                        PAGE2
TABLE2
=======                                       ======
                                    CREATE        CANCEL
                                                                                                                   Navigation
                                                                                                                   ========
(Text Field) Address1:                                                                                  Page1 (link to goto page1)
(Text Field) Adress2:                                                                                   Page2 (link to goto page2)
                                                                                                                Page3 (link to goto page3)
                                                        PAGE3
                                                      ======
TABLE 3
======
                       CREATE        CANCEL
                                                                                                                     Navigation
                                                                                                                   ========
(Text Field) SSN:                                                                                         Page1 (link to goto page1)
(Text Field) Phone No:                                                                                Page2 (link to goto page2)
                                                                                                               Page3 (link to goto page3)
The requirement is...The users want to "HIGHLIGHT" the navigation link when they fill (create record..even if they enter one field in that) one page and go to next page..
Ex:  If they start entering page 1 and hit CREATE button. and navigate to page2 ..i need to highlight page1 (Navigation list) for letting the users to know that they started that record on  "page1".Could someone please give me some suggestions..to solve this
thanks

Answer 1

Hi,
This is possible, but it will take a bit more setting up to achieve.
1 - Create 3 Application Items. One for each page called, say, PAGE1_COLOUR, PAGE2_COLOUR and PAGE3_COLOUR
2 - Create Application computations for each. These should be Before Header, SQL queries something like (adjust for each page):
SELECT CASE WHEN nv('APP_PAGE_ID') = 1
THEN 'blue'
WHEN (:P1_A1 IS NOT NULL OR :P1_A2 IS NOT NULL OR :P1_A3 IS NOT NULL)
THEN 'red'
ELSE
  'black'
END
FROM DUAL3 - On your list entries, change the List Entry Current for Pages Type to Never as this is no longer needed
Also, on your list entry, go to the User Defined Attributes section at the bottom and add the following into attribute 1 (adjust for each page):
&PAGE1_COLOUR.4 - Finally, on your list template, because we have switched off the "Current for pages" setting, we only need to update the "List Template Noncurrent" setting. Change this to something like:
<li><a href="#LINK#" style="color:#A01#">#TEXT#</a></li>The Before Header computations will now calculate the colour to use for each page. The User Defined Attribute 1 setting will pick this up and the #A01# entry in the template will be converted to this value.
As there are 10 available User Defined Attributes, you could extend this principle to do a lot more with styling links or even changing where the links point to.
