Re: developer 2000 stacked block level scroll bar

Hello again,

I have never used the solution commercially, but I did put a quick test form together to satisfy my own curiosity (and to make sure it works!).

The stacked canvas has the following properties: Displayed = True
Width = 14 (width of block scrollbar)
Height = 330 (depth of multi-record block) Window = MAIN_WINDOW (set this to your Window) X Position on Canvas = 0
Y Position on Canvas = 0
View Width = 14
View Height = 330
Display X Position = 725
Display Y position = 87

Block properties:
Scroll Bar = True
Scroll Bar Canvas = SCROLLBAR_CANVAS (set to your stacked canvas) Scroll Bar Width = 14
Scroll Bar Height = 330

I can't actually see the scroll bar on the canvas in Developer, ie. I can click on the stacked canvas in the Object Navigator, and see the stacked view outline in the Layour Editor, but there is no scroll bar inside it. At run-time the scroll bar appears and can be successfully re-positioned. I'm not sure why this should be the case. A small amount of boilerplate text, added above the scrollbar, does appear in the canvas Layout Editor.
