Hi Parry,
The dynamic programming way is follows:
you need to first get a reference to the root element 'ROOTUIELEMENTCONTAINER' from the view reference available within the wddomodifyview method. the variable returned is of type cl_w_uielement_container. you can use the method get_root_element( ) of the interface if_wd_view for this purpose.
next get a reference to the transparent container by using the method get_child of the class cl_wd_uielement_container( using the variable returned from the prevoius call) and cast it to a variable of the class cl_wd_transparent_container. to this method you need to pass the id of your transparent container.
Once you have the reference you can use the method set_visible( ) to make the container visible or invisible at runtime.
However you need to be careful about the placement of this code within the wddomodifyview method because it would get executed every time. Thus the best way is to store the reference to view in a component controller the first time and later on use this attribute anywhere within your component.
