Can i change the view embbed in viewContainerUIelement in code?

[Former Member]

I have defined a viewContainerUIelement in my MAINVIEW and several VIEWs in my component. Each time, I start the WD application, I need the viewContainer choose one of the VIEWs to show according to some conditions. How can i realize it in my code?

Hi,

After Embedding all the required views in the View UI Container , link them through the plugs and fire the relevent plugs of the View which want to display.

Eg, if Embed View A, View B, View C in the Main View,Link these Inbound plugs from the View A, View B ,View C to Main Outbound Plugs .After that call the Relevent outbound plug in the WDOINIT method in the Main View

Although Navigation Plugs are the correct normal approach, please note that there is also a pure coding approach also. This way not all navigation plugs have to be defined in advance, allowing for really dynamic navigation. For this you can use the method do_dynamic_navigation of the view API:

data:
    l_api_main type ref to if_wd_view_controller.
  data: target_component_name type string,
        target_view_name      type string,
        source_plug_name      type string.
   l_api_main = wd_this->wd_get_api( ).
    try.
        l_api_main->do_dynamic_navigation(
            source_window_name        = 'MAIN'
            source_vusage_name        = 'MAIN_VIEW_USAGE_1'
            source_plug_name          = source_plug_name
            target_component_name     = target_component_name
            target_view_name          = target_view_name
            target_plug_name          = 'DEFAULT'
            target_embedding_position = 'MAIN_VIEW/VIEW_CONTAINER').
        .
      catch cx_wd_runtime_repository .
        raise exception type cx_wdr_rt_exception.
    endtry.

This method even allows you to call external components without declaring a component usage.
