17. Navigation between SearchPage to Overview Page(Window to Window within a Component)

We need to develop an application in such a that, when user clicks on resulted hyperlink, it will navigate to overview page as:

First, Lets create navigation between 'searchpage' to 'overviewpage', then we will create navigation link in other chapter.

Let me show you schematic diagram of navigation.

We will start with numeric tasks and then we will do the alphabetical tasks.

1. Hyperlink to Purchase_date.

 We need to implement P_Getter for making Purchase_date as hyperlink.

Goto-> Attribute Purchase_date of ResultView, as generate P_getter method as:

Expand 'Struct.purchase_date' and double click on 'GET_P_PURCHASE_DATE' and embed below mentioned code.

Create a evenhandler with the name 'PURCHASE_DATE'.

Now,
2. Outbound plug for result view. Select Resultview, goto 'Outbound Plugs', right click 'Create', specify name of the outbound plug as 'toOVPV'.

3. Similarly, create outbound plug for 'MainWindow' as 'toOVPW'.

4. Similarly, create inbound plug for 'WinOVP' as 'fromOVPW'

5. Similarly, create inbound plug for 'OverviewPage' as 'fromOVPV'.

6. Need to create a navigation link between two windows. Goto 'runtime repository'

Select 'Navigation Links', right click 'Create'.

Provide Id as : fromSPtoOVP (From Search Page to Overview Page), and source and target as below.

7. what is this regards, we will pause it, will discuss about it later.

Now, Let s implement 'alphabetic tasks'.

a) Implementing eventhandler 'PURCHASE_DATE' as:

OP_TOOVPV( ).

b)  Implementing Outbound plug of ResultView-> OP_TOOVPV( ). Double click on Resultview's outbound plug.

" Calling Outbound plug of MainWindow from ResultView outbound plug as

Code :

 data: lr_window TYPE REF TO cl_bsp_wd_window.

  lr_window = me->view_manager->get_window_controller( ).

  lr_window->call_outbound_plug( 'toOVPW' ).


c) Navigating from MainWindow to WinOVP.Implementing MainWindow's Outbound plug as:

method OP_TOOVPW.
    me->view_manager->navigate( source_rep_view = me->rep_view
outbound_plug = 'fromSPtoOVP').
endmethod.


d) Calling inbound plug of Overview Page from WinOVP's Inbound Plug.

method IP_FROMOVPW.
  DATA : lr_view TYPE REF TO ZL_ZMOB_DTL_MOBILEDETAIL2_IMPL.
  lr_view ?= get_subcontroller_by_viewname( 'ZMOB_DTLCMP_DNX/MobileDetailsOVP' ).
  CHECK lr_view IS NOT INITIAL.
lr_view->IP_FROMOVPV( ).
endmethod.


We are done with the changes. Now its time to 'test' the application.

Okey let's test it.

OOPsssssssssss....

we got an error.

what it say

• Direct navigation from window ZMOB_DTLCMP_DNX/MainWindow to window ZMOB_DTLCMP_DNX/WinOVP is not allowed

O noooooo, So, we cannot navigate from windowto window of same component.Then what to do... Let's see in next chapter. Solution for Navigation from window to window
