WebDynpro - How can I display data selected from a table in a pop-up?

I have a table with element, and a "delete" button. When I select one element, if I push this button, it open a pop-up with the same table but ONLY with the element selected ...

There is the code of "action" for the "delete" button :

publicvoid onActionDeleteElement(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
   {
   //@@begin onActionDeleteElement(ServerEvent)
  logger.entering("onActionDeleteElement");

   IWDWindowInfo windowInfo =(IWDWindowInfo) wdComponentAPI
   .getComponentInfo().findInWindows("Popup_View");
   IWDWindow window = wdComponentAPI.getWindowManager().createModalWindow(
  windowInfo);
  window.setTitle("Selected");

  window.show();


  logger.exiting("onActionDeleteElement");
   //@@end
   }

I really need help please.

Thank you.
