UniScrollBox if vertical scrollbar not at top position at compile time

[dpfmp]

Hi,

Using 

UniSession.AddJS(uniScrollbox.JSName+'.getTargetEl().scrollTo(''Top'', 0, true);');

gets the vertical scrollbar to the top position at runtime but if the vertical scrollbar was left anywhere but at the top position at compile time, there is no way to reach the top part of the scrollbox anymore.

 

If you drag the 2 scrollbars to their bottom position and click 'ScrollTo TOP' button, the left scrollbox is going back to the top position but the MID scrollbox returns to button4 and the first 3 buttons are unreachable. The position of the vertical scrollbar at compile time becomes the new top of the scrollbox at runtime.

I made a small test application: ScrollBoxTest.7z

Delphi 10.1 UniGui 1.90.0.1496

ScrollBoxTest.7z

Hi,

Yes, there is a bug: TUniScrollbox actually changes the top and left properties of the controls it contains, when you scroll.

We will fix this issue.

Confirmed.

This behavior is by design. However, I will try to improve it.

Hi Farshad,

Is there a way to force the scrollbar to the top position in the OnBeforeShow event?  

The VCL version  has a VerticalScrollBar.Position that can be used to bring it back to the top.

As it is,  any uniscrollbox with a vertical scrollbar left in a position other than the top position at design time will make part of it unusable at runtime.

Thank you for looking into it.

Hi,

At the moment, the best way is to set "top = 0" in designtime.

Hi Sherzod,

'Top' has to do with the UniScrollBox and not the vertical scrollbar. I guess what you mean is that for every uniscrollbox having a verticalscrollbar at design time, I should always drag the scrollbar at the top position before compiling.

That is what I'll keep doing.

Thank you

Fixed.

I still have this behavior, sometimes in design I end up forgetting the scroll in any position, and when running, it shows me an empty area at the top of the scroll, this seems to me the same problem as the friend mentioned above, which seems to have been fixed . I will attach prints for better understanding.

 

 

IF YOU EXECUTE THIS WAY IT WILL BE LIKE:

 

 

STAY WITH THIS EMPTY AREA

 

COMPILED WITH SCROOL OUT OF INITIAL POSITION

Can you reproduce this issue with this demo?:

\FMSoft\Framework\uniGUI\Demos\Desktop\ScrollBox

 

[Gustavo_GRSoft]

I can't because the project is very complex and has several database connections. Is there any way to make the scrollbox go to the top dynamically?

I am not asking for a test case from you.

This is a standard UniGUI demo. I mean, could you reproduce your case in this demo example?

[Gustavo_GRSoft]

I can't because the error only happens when I feed a dbgrid and only happens in this situation, the rest of the system works perfectly

TeamViewer?

[Gustavo_GRSoft]

I cannot open TeamViewer, it is prohibited inside the company. I can make a video if you want.
