Hi Boki,

Is it possible to indicate by how many rows a NextGrid should scroll when using the mousewheel ?
My grid has 60 pixels rows (height) and displays about 3.5 rows at a time:



But when I use my mousewheel to scroll, it scrolls to about the seventh row... So I can't see some rows unless I use the scrollbar.

Hello Gousti,

Do you think about holding down mouse wheel and moving mouse up/down?

[GoustiFruit]

It's a possibility but I never use my mouse this way, it's easier to simply scroll: holding down the mouse wheel and moving doesn't allow precise scrolling, it may be pratical when you want to scroll really fast on a very long page, but not to scroll by 2-3 items at a time...

[GoustiFruit]

Sorry to ask again, but can you do something ? It's a really annoying behaviour, one wheelscroll is equivalent to almost 2 pages scrolls :-\

Hello Gousti,

I have test it and it seems that all is fine

Please check attached demo, maybe I am doing something wrong:

Hi Boki,

i have tested your exe and on my PC (XP/sp2, Logitech mouse) it scrolls 2 records per
1 mousewheel-step, for me this looks okay.
If GoustiFruit has another behaviour, then maybe because of another mousewheel setting?

best regards,

Hello,

It may be, also when CTRL is pressed-scroll step is larger.

Hi,

on which setting depends the amount of rows ?

On my pc the grid jumps always three rows when using the mousewheel, disregarding the setting in the control panel.

Hello Frank,

Mouse wheel up/down call VertScrollBar.Next (or Prev). Maybe this settings may be controled.

Hello Boki,

Sorry for replying so late :-\

I have the same - normal - behaviour as user22 when using your demo: 2 rows for 1 scroll, 11 rows when pressing Ctrl.

But I still can't figure out why it works differently in my application :-( I'm using some invisible fields in my Slides, could it be the reason ?

[Boki (Berg)]

Hello Gousti,

Maybe if you have hidden slides (entire slides)?

regar

[GoustiFruit]

No, all my slides are visible.
At first I thought it could be because some of my invisible fields were out of the slide in the designer view, but I put them back in and the problem remains...

Hello Boki,

I think I've found the origin of the problem (but no solution, I count on you for that !)
-> My grids are all contained within a Panel, with Align property set to alClient. (I need the panel to customize the border of my grids the way I want, as it's not yet possible with NextGrid).
The problem only occurs in this case.

I hope it will help you resolve the problem.

Thanks,
Gousti.

Hello Gousti,

Can you only send me a small demo project of it. This will really help me to find it faster.

Hello Boki,

I sent you a sample project, I don't know if you received it because it doesn't appear in my "Sent items" !?

[Boki (Berg)]

Hello Gousti,

I have receive it in my PM. Thank you, I will check it now.

[Boki (Berg)]

Hello Gousti,

I see now , I will try to fix it now.

Thank you for you demo.

[GoustiFruit]

Thanks ! Nice to see I was not crazy

Hello Gousti,

It seems that this is definitelly related to whell step I don't know how this may be changed

You may download MS Power Toys -> Tweak UI

http://www.microsoft...ppowertoys.mspx

and you will see inside Mouse -> Wheel for how many rows whell scroll.

I already have TweakUI installed, and my mouse settings are default (scrolls 3 lines at a time).
I don't think the problem relies there if you were able to validate the difference of behaviour when the Grid is client aligned in another control !?
