ScrollBar on Form

Expand Post »
I have a Form witch scrollbars that is called Form2.
Is there any way to programatically go to the top of the Form without having to scrollup with the mouse ?
So if you have scrolled down to the end of the form. Is it possible to press a button that consist code that will go to the top of the Form2 ?

Re: ScrollBar on Form

Yep.

You can set the form's ClientOrigin property (which is a tPoint)

or

You can set the position property of the form's HorzScrollBar and/or VertScrollBar.

Have fun!

Re: ScrollBar on Form

Yes, you are missing all the words I put in bold in my first response.

Re: ScrollBar on Form

I am not sure if I understand.
If I write Form2::VerticalScroll I cant find ClientOrigin or position as members.

I can´t find position or ClientOrigin as member to Form2:: either, so I think I am a bit stuck.

> I am not sure if I understand.
Ed was afraid that might happen. Duoas isn't describing Windows Forms, so his suggestions won't work for you. The code you want is Form2::VerticalScroll->Value = 0; , but if Ed remembers correctly, that won't work as well as you probably want with the autoscrolling properties of a form.

Re: ScrollBar on Form

Ed is close. Jennifer is using C++Builder.

You can set
Form2::VertScrollBar->Position = 0;

My apologies on ClientOrigin. I just looked it up and it is a read-only property. Alas.

Keep in mind my capitalization might be a little off.

I admire your tenacity and efforts, but either your documentation really stinks or you still need to work on searching it. (I just got BDS 2006 and it's documentation really stinks.)

Hope this helps.

Re: ScrollBar on Form

No problem. I am using this code now and it seems to work fine for this purpose.
Thank you...
