Steps to Reproduce Behavior

1. Create a new Windows Application project, Project1, with Visual J++ 6.0.



2. Add a WFC List View control, listView1, to the form.



3. Select the items properties from listView1's Properties window and add two new items, listItem1 and listItem2.



4. Add a WFC ContextMenu control, contextMenu1.



5. Select the contextMenu property from the listView1 Properties window and associate it to contextMenu1.



6. Double-click on contextMenu1 and one item, menuItem1.



7. Continue by adding subitems menuItem2, named small, and menuItem3, named large.



8. Double-click on menuItem2 and add the following function call to the Click function:




listView1.setView(ViewEnum.SMALLICON);	 

9. Double-click on menuItem3 and add the following function call to the Click function:




listView1.setView(ViewEnum.LARGEICON);	 

10. Add the following method:




private void contextMenuPopup(Object source, Event e)
{
   MenuItem currentItem = null;
	
   switch (listView1.getView())
   {
      case ViewEnum.LARGEICON:
         currentItem = menuItem3;
         break;

      case ViewEnum.SMALLICON:
         currentItem = menuItem2;
         break;
   }

   menuItem2.setChecked(false);
   menuItem3.setChecked(false);

   currentItem.setChecked(true);
} 

11. Select contextMenu1 and, in the Properties window, select the events listing and associate the pop-up event with the contexMenuPopup method created above.



12. Compile and run the sample.



13. Right-mouse click on List View control and notice the "small" menu item is selected.



14. Select the "large" menu item and close the context menu.
