Reference to Custome Controller from View controller

[Former Member]

Hi all,

I have created a custom controller and inside that i have a method. i need to execute that method from a view controller, similar to executing a method in the component controller. to execute a method in the component controller i use the WD_COMP_CONTROLLER attribute to refer to the component controller. similarly how to i refer my custom controller from the view, or is there any other way? it would be great if someone can help me with this.

Hi Malinda,

Proceed in this manner:

Open your view, then go to the PROPERTIES tab of the view. Click on the create button and add the custom controller you have created. After doing this, go to the Method tab of the view and then simply call the custom controller method with the help of code wizard in any method. The code will look like :

DATA lo_zcustom TYPE REF TO ig_zcustom .

lo_zcustom = wd_this->get_zcustom_ctr( ).

lo_zcustom->test(

).

Here zcustom is the name of my custom controller and test is the name of the method.

I hope it helps.

Regards

Arjun

hi,

Lets say view1 has the event ONACTIONNAVIGATE and you want to call a method 'start_navigation' in the custom controller named 'navigation'.

Use the following code.

METHOD onactionnavigate .

DATA lo_navigation_controller TYPE REF TO ig_navigation.

lo_navigation_controller = wd_this->get_navigation_ctr( ).

CASE navigation_type.

WHEN 'BACKWARD'.

lo_navigation_controller->start_navigation( if_fitv_fpm_api=>gc_navigate_backward ).

WHEN 'FORWARD'.

lo_navigation_controller->start_navigation( if_fitv_fpm_api=>gc_navigate_forward ).

ENDCASE.

ENDMETHOD.

Dear Malinda,

when ur using the custom controller we need to call the Read context Node/Attribute from the Webdynpro code wizard then call the method .
