I've got a textbox that's controlled by a scrollbar and I want to show a page up & down arrow only when where are more pages either way but can't figure out any way to achieve it.

I've tried Container(scrollbar_id).HasNext and IntegerGreaterThan(Container(scrollbar_id).NumPages,9) (9 being the max number of lines visible) but neither work.

Any ideas?

Thanks.

if at all, then it would be "Container(container_id).HasNext" or "IntegerGreaterThan(Container(container_id).NumItems,9)" (which would probably equal to "IntegerGreaterThan(Container(container_id).NumPages,1)". Using NumItems or NumPages still wouldnt work properly because it doesnt take the actual focused position into account.
If "Container(container_id).HasNext" (or just "Container.HasNext") does not work then report back and I´ll give it another try.

EDIT: oops, forget that answer, forgot that youre dealing with a textbox when writing the answer (if it works with the id of the textbox I would be surprised, but also worth a try)

The only other thing I can imagine for now is to add a fake scrollbar with <showonepage>true</showonepage> and use control.IsVisible(fake_scroll_bar_id) then.
That approach cannot distinguish between HasNext and HasPrevious though.

I tried all of those combinations but nothing is returned from either the scrollbar or the textbox.

I had to do it the long-winded way using a pen and paper and some calculations -

Code:

This covers me up to 27 lines (the max I found was 22) but I still think we should be able to use HasNext and HasPrevious for scrollbars.

That's a lot of StringCompare's for just... two arrows !. IMHO you should dump them and use a classic scrollbar.

Solved it an easier way if anyone wants to use it in the future.

Up arrow -

Code:

<visible>IntegerGreaterThan(Container(ID_OF_TEXTBOX).CurrentPage,1)</visible>

Down arrow -

Code:

<visible>!StringCompare(Container(ID_OF_TEXTBOX).CurrentPage,Container(ID_OF_TEXTBOX).NumPages)</visible>
