[WiX-users] Count of items in aListBox

[Vuchuru, Surekha (SBT US EXT)]

Hi Everyone,
 
I have two listboxes in a Wix UI. When I select an item on left side
listbox and click Add button, that item should be added to the right
side listbox.
I have written a C++ CA which gets triggered when we select an item and
click Add button. I am using WcaAddTempRecord to add that selected item
to ListBox2.
There are a couple of questions that I have w.r.t the same
 
1) How can we know the count of ListBox2 items. This needs to be known
because WcaAddTempRecord takes a paramter for the position of the item
being added. So, i need to know the count whenever I add a new item to
that ListBox.
2) is it possible to refresh Wix UI as and when I add items to ListBox2.
3) How can we make sure multiselection works for a ListBox.
 
I appreciate your time.
 
Thanks and Regards,
Surekha Vuchuru
