Listbox not showing scrollbar

[Guest]

I tried a listbox in C# visual studio .net 2003. I had 4 items in the list box (numbers 1, 2, 3 and 4
When I run it on the pocket pc 2003 emulator I do not see any scrollbar and I see number 1. What am I doing wrong?

When the dimensions of a listbox are large enough (at least 2 lines visible
on the screen) scrollbars are showing. So you're listbox's height is
probably too small to render scrollbars. This is funny, because they do show
up in the designer. I would call this a bug, since the user does not see
that more items are available in the listbox. It is possible scrolling
through the list using the up/down arrow keys, to the listbox itself does
function. I just checked and I see the same behavior on a device. Anyway,
adjust your listbox height and you will get scrollbars.

Thanks Maarten
I had to change the ListBox height to 30 to make the scrollbar show which means I have to show 2 lines. I would say it is a bug! Another problem I see is also that I can only go from listbox height of 15 to 30 , I can not select 24
I would prefer to show only one row with a scrollbar like a drop down listbox. Do you know how? I changed the form grid interval to 4,4. It did not help

Actually the height of the ListBox is adjusted such that complete items will
be visible. This is done mainly for scrolling purposes, which means that you
can't select any arbitrary number as height of the ListBox.

Sorry... you like to have ListBox that shows just ONE item at a time?
Then what you need is not a ListBox but
a) a ComboBox (here the user can see one row and can push a button to see
the list)

b) an EditBox or just a Label - combined with an up/down button beneath it.
Then the user can see one item and can "scroll/switch" thru all item by
pushing the up/down arrows. Of course you need to hold the Data off-screen
in an ArrayList or something
