Hi Srilalitha ,

You need to add custom controller first, only then you can call any method of custom controller in view controller. Just go to the Property tab of your view and click on add controller button, add the custom controller. Now you can call any method of your custom controller in view controller with the help of code wizard.

I hope it helps.

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.

Thanks,

Dear srilalitha,

You can use code wizard (CTRL + F7) to call the method in custom controller.

Once you opened the code wizard , it show the option Method call in Used Controller

select the option and select the controller Name and then method name.

Hi,

Please click the magic wand (CTRL+F7).

Choose method call in current controller. Enter the controller name and choose the method.

You can get the reference to your controller like this.
