The first test already failed.
I had no problem inserting a record with the key value empty or 0. The minvalue for that field was 1000.
Here is a gif to show the problem:

Line 256 is another example.

This is how it could look like:

Result := ( Assigned(FDataLink)                ) and 
          ( Assigned(FDataLink.DataSource)     ) and 
          ( not readonly                       ) and 
          ( not(csDesigning in ComponentState) ) and 
          ( FDataLink.Active                   ) and 
          ( FDataLink.CanModify                ) and
          ( FDataLink.Editing             or 
            FDataLink.DataSource.AutoEdit      )     ;

I have not tested it yet, but comparing current and new source, I came across the statement in line 203 which is more than 200 characters long. That’s not readable anymore. Here’s the alternative:

if ( CharInSet(Key, [#32..#255])    ) and
   ( FDataLink.Field <> nil         ) and
   ( not CharInSet(Key, ['0'..'9']) ) and
   ( Key <> {$IFDEF DELPHI_XE}FormatSettings.{$ENDIF}DecimalSeparator) and
   ( Key <> '-'                     )     then begin

Here it is clear that you accept any characters not present in a number.

I reduced the problem to a bare minimum.
Attached is the result.

I was able to replicate the problem.
There may be too many files in the zip file, but I don’t know which files are necessary to replicate the problem.
Just click on the Show Form button and see that the bottom panel is not visible, Change the width of the form and the panel shows up.

I can reproduce your problem.

[HeDiBo]

In order to get the hints on headers in cxGrid on the right position, you need to define a TcxHintStyleController and do some manipulations in its OnShowHint event.
Unfortunately, if SkinManager is active, that code is not executed.

Enclosed is a sample project.
If you remove the TsSkinManager, TsSkinProvider and the TsAlphaHints components, the OnShowHint event is called and the hint is shown at the right position. As it is, the OnShowHint event is not called.

About the cxGrid: you’re right. I didn’t know that.
However the AutoAlignment setting is still a problem. And since you’re saying that the coordinates of the hint window are determined by cxGrid, the AutoAlignment problem could be solved, I think.

[HeDiBo]

What did your provider say?
Because the forum is still very slow. Also there is no indication that the site is at work, which may cause repeated actions.

It seems a compiler error. Don’t bother.
Please close this topic.

Strike that. The reply is in a wrong topic.
The problem with the missing controls is extremely important! And not solved in 15.15

My experience with manually inverting images is, that the edges of anti-aliased pictures don’t look OK. If you have a solution for that, your suggestion is excellent. 🌹

[HeDiBo]

I understand. Please close this topic.

[HeDiBo]

I would do that, if the AutoAlignment property could be set on an individual basis. But I like it almost everywhere, except here.
I think you should come up with a better solution.

Even if AutoAlignment is off, the hints are still in the wrong place for grid headers. Have a look at the video. As you can see, the hint covers the header field completely.

I don’t think inverting the colors of an image is a good idea. It could have adverse effects on color images.

I only want to use it for small 2 color black and white images.

[HeDiBo]

That’s why I suggested to include the FontAwesome in my distribution and use a character in stead of an image.
However, why is it working (the inverted image) in cells that are not highlighted?

I have another situation where Hints appear at the wrong place: hints for column headers in a TcxGrid. Attached a GIF that shows it. It is always wrong, not related to HandleDisabledCtrls

I tested with enabling the Application.ProcessMessages. The result was disappointing, because AV’s might occur.
However putting the statement here (near the bottom of the ActivateHint procedure) did not show that averse effect yet.

          AlphaBmp := nil;
        end;
      end;

    Application.ProcessMessages; // Patch for refresh of columns in cxGrid
    Manager.State := hsNormal;
    Manager.FHintPos.x := -1;
{$ELSE}
    inherited;
{$ENDIF}

[HeDiBo]

If skin is dark, make the white parts black, make the black parts white and leave the transoarent parts untouched.
In Dutch that’s called a negative image, but the better term in English is inverted 😁

[HeDiBo]

These are two devastating samples of this bug.

In ScreenToGif7 you see that an inserted record does not receive the entered text at all. In stead the value is set to 0 which is even below the minimum value property.

In ScreenToGif8 you see a record being inserted, which is rejected because of duplicate key and then the insert is cancelled. After cancellation the key value shows the wrong value, making the record shown in the grid different from the record in the edit field!!
