Hi all,

Thanks

Have a look at the methods in the class if_wd_view. You have options to retrieve each element by specifying its ID, or a group of elements also. The reference to the view will be available in the Modify View method and you can call these methods from there. However, I do not think you can retrieve all input fields or something specific like that.

yes, you can do that.

1. you can get the root container. view->get_root_element( ).

2. get all UI elements based on the root container. lr_container->get_children( ).

3. loop UI elements. if there has container elements. then do the same thing as below.

lrs_child->_DEFINITION_NAME. this can help you check the type of UI element.

eg: BUTTON, GROUP..

so that you can get all elments in the view.

hi ,

declare an attribute x type ref to if_wd_context_node.

Then call x->get_elements().

Have a look at how SAP does it in the CL_WD_DYNAMIC_TOOL class. There is a local class method (LCL_MANDATORY_CHECK=>GET_MANDATORY_ELEMENTS). In here SAP goes back to the database where the WD Metadata is stored - tables WDY_UI_PROP_DEF and WDY_UI_ELEM_DEF to get the internal ids of the particular UI element types. They then use the IF_WD_VIEW class and method GET_ELEMENTS_BY_CID to read the UI elements in question.
