Sure, just have something that maps from the requested item number to 
the actual item number in your data.  For example, if you have 10 items 
in your data set, and you want to hide the 5th one, then your filter map 
could be as simple as:

	filter = [0, 1, 2, 3, 5, 6, 7, 8, 9]

Then when the listctrl asks for the number of items return the length of 
filter instead of the actual items, and when it asks for some data 
values based on some displayable index then just run that value through 
the filter, like this:

	self.items[self.filter[index]].text
