Page-Up and Page-Down buttons on a large Form so user can jump to top of Form rather than using Scroll Bar

[Ant-Tech]

is there any way known to add "Page-Up" and "Page-Down" buttons on Large Forms, so the user can Jump to Top or Bottom of a Form; rather than using Scroll Bar ?

Many thanks in advance.

What if you had the buttons activate a particular field or a hidden dummy button?

What Robin said should work or you can even tie an onkey event telling the pageup or pagedown key to focus on the object at the top or bottom of the form.


I have not tested this but I think it should work.

	IF a_user.key.value = "{down}" THEN
	    'set a_user.key.handled = .t. to prevent the key stroke being passed on to the Form
	    a_user.key.handled = .t.
	    topparent:BottomObjectName.activate()
	end if 

	IF a_user.key.value = "{up}" THEN
	    'set a_user.key.handled = .t. to prevent the key stroke being passed on to the Form
	    a_user.key.handled = .t.
	    topparent:TopObjectName.activate()
	end if

you could use tabbed object to achieve the same effect. for some reason you do not want you could try
place a frame in the form and copy the frame to duplicate. place controls in the frame 1 and as well as frame2 and then place two buttons.
the first button will hide frame1 show frame2, the second one will do opposite. when all good bring the frames together. essentially this will mimic page up down
I can do testing later on to prove this theory.

Many thanks Guys.

I'll try them all and see which I will use. All 3 have their merits for different Forms.

Thanks again.

I did a little testing and while the topparent:ObjectName.activate() does set the Focus to that object, it does not move, scroll the window or anything like that.

Preston, that was my finding as well - no scroll.

GGandhi - you are not talking about a conditional object are you? I would like to see your frame example.

Edit: I tried adding a header and footer section to a form designed to display all the fields in a column (the default form), making it 10" high.

I added a Page Down button to the header section and had it activate the last field on the form.
I copied that button to the footer section as Page Up and had it activate the first field on the form.
I then set the form height to 6", selected Use Form Height, and made it sizeable.

Using the OnKey event for the form to change the actions for the PageUp and PageDown keys should work the same without the need for buttons.

If you look at the example in AlphaSports for the Customer Information form - you can see this in action by reducing the form a bit to make the scroll bar show. And you can test your script there.

Here's an example form you can save to your desktop & import into AlphaSports: FormScroll.a5pkg

robin:

i tried to create a test form based on alphasports, it involves not just showing and hiding frames but also all involved controls snd their labels. it seems to me my way is way too complicated than the tabbed object.

I was able to do the concept I had and it works but I still think tabbed object is easy
take al look

Not by a PC this week to try, but wouldn't adding sendkeys pageup/pagedown
to Preston's code work, and be a quick solution?

Good thought but those keys change records not view.

As a test try this - it works great and you can see the direction it moves.

sys_send_keys("{down}{down}{down}{down}{down}{down}{down}{down}{down}{down}{down}{down}{down}{down}{down}{down}{down}")

add a topofform and bottomofform object (possibly a hotspot) on the page - in the appropriate place - and have a button in the toolbar for each that activates one or the other.

An image of your form will tell us if you are jumping around in an embedded browse or actually have a large form with many objects on it.

Thanks to All.

I am trying out the various options and will keep this Thread updated.

The Form has lots of fields and I know i can put them where I want, but on this occasion; I wanted to build a Blank Form using all fields in the Table and keep them all in Column format. The Form has 5 Pages which is a Tabbed Form as you will all know.

Thanks again.

Leslie.
