We should use the concept only when it is not possible to construct the Web Dynpro Component by declarative means, for example : the layout is not yet known at design time. And last but not the least, a word of caution : On the parallel lines, we may use the class cl_wd_text_edit for "TEXT EDIT " UI element and Lo_dropdown = cl_wd_dropdown_by_idx=>new_dropdown_by_idx(īind_texts = LV_SAP id = dd_indx_id view = wd_this->mr_view ).Ĭl_wd_matrix_head_data=>new_matrix_head_data( element = lo_dropdown ).

The reference using the attribute mr_view. The interface of method wdDoModifyView provides a parameter VIEW, which is a reference to an object of type IF_WD_VIEW representing the instance of a view at runtime. įor generating the unique dynamic node every time, I have used the attribute "count_sys". I am generating the dynamic node SYS00, SYS01. I have created a transparent container "TC_SYSTEM". However add_new_child_node ( ) method not only allows to create a context node, but also to create related attributes.ĮxampleFollowing example would help in understanding dynamic layout manipulation better.Dynamic Drop Down By Index This method has to be called once for each attribute. Dynamic Context AttributesAttributes for the dynamic nodes created can be created by calling the method add_attribute ( ) from the reference to the metadata of the node. This method hands back the reference to the metadata of the new node. To create a new node, the method add_new_child_node( ) can be used. In order to create a new independent context node a reference to the metadata of the context root node is done via method wd_context->get_node_info( ). This layout data contains the description, at which position in the layout of the container an embedded UI element has its place. Įvery UI element has layout data, in accordance with the embedding container. To describe it, a layout is selected for every container: Flow Layout, Matrix Layout, or Row Layout exist. In a view, a number of UI elements are laid out in relation to one another in containers. To use the dynamic layout manipulation correctly, we must understand the structure of a view. It does not use pre-defined UI elements and nodes, while writing a dynamic program, we need to define the UIs. This is concept of dynamic layout manipulation. Sometimes it may become necessary to layout the interface structures of application only at runtime. Particular about dynamic layout manipulation. Here I would like to discuss some interesting concept about dynamic programming in WDA, in Web Dynpro ABAP is the standard SAP User Interface technology based on MVC paradigm.
