When using
ImageEnMView1.AttachedImageEnView := ImageEnView1
Should the file be loaded using ImageEnMView1 or ImageEnView1
When loading using ImageEnMView1, the navigation doesn't work on page 1. You CANNOT MouseWheel back to page 1 once you've left it.

Hi Jeff
In the latest beta, you can check for iecsUndo in the TImageEnView.OnImageChangeEx event to detect changes due to undo/redo:

Ok. But please add a new event OnAfterUndoRedo to a future release.

Follow up.
When using FThumbs.AttachedImageEnView := FViewer;
is there a way to have the selected TThumbs image updated automatically whenever the user does an edit in FViewer? Similar when the user presses Undo to the edit in the FViewer.
I want the thumbnail in FThumbs to always reflect the state of the image loaded in FViewer.
If not auto way to do this on a FViewer.Undo then a OnAfterUndoRedo event would be helpful.

Found the issue. Just add
FThumbs.StoreType := ietFastThumb;
Before loading the file. With this set, you can't scroll back to page 1.

Hi Jeff
I added this code to a new form:
procedure TForm1.Button2Click(Sender: TObject);
var
FViewer : TImageEnView;
FThumbs : TImageEnMView;
begin
FThumbs := TImageEnMView.Create(Self);
FThumbs.Parent := Self;
FThumbs.Width := 500;
FThumbs.Align := alLeft;
FViewer := TImageEnView.Create(Self);
FViewer.Parent := Self;
FViewer.Align := alClient;
FViewer.AutoShrink := True;
FThumbs.AttachedImageEnView := FViewer;
FViewer.MouseWheelParams.Action := iemwNavigate;
FViewer.MouseWheelParamsAlt.Action := iemwZoom;
FThumbs.MouseWheelParams.Action := iemwNavigate;
FThumbs.MouseWheelParamsAlt.Action := iemwVScroll;
FThumbs.MIO.LoadFromFile('D:\TIFF\MM color&bw__4pages.tif');
end;
Whether I mouse over the thumb control or the viewer it works as expected.
Can you test the attached project.
What version of Delphi are you using?

I'm still having an issue mouse wheeling back to the first page.
FViewer := TImageEnView.Create(AOwner);
FThumbs := TImageEnMView.Create(nil);
FThumbs.AttachedImageEnView := FViewer;
FViewer.MouseWheelParams.Action := iemwNavigate;
FViewer.MouseWheelParamsAlt.Action := iemwZoom;
FThumbs.MouseWheelParams.Action := iemwNavigate;
FThumbs.MouseWheelParamsAlt.Action := iemwVScroll;
I loads with page 1 displaying in the Viewer, but then when I mouse wheel down to page 2 and then back to page 1 the Viewer still displays page 2, but the Thumbs pane does select page 1.
So page 1 gets selected in the thumbs pane, but the does NOT get loaded in the Viewer.
By the way, I'm loading a multi-page TIF file. It works fine when I load a PDF.

Hi
You should be loading it using ImageEnMView1.MIO.LoadFromFile();
(Except in the special case of PDF files).

Should the file be loaded using ImageEnMView1 or ImageEnView1?

Hi Jeff
I'm not seeing that. Try adding this code:
// Mouse wheel scrolls through the images (with secondary actions if Ctrl is pressed)
ImageEnView1.MouseWheelParams.Action := iemwNavigate;
ImageEnView1.MouseWheelParamsAlt.Action := iemwZoom;
IEFolderMView.MouseWheelParams.Action := iemwNavigate;
IEFolderMView.MouseWheelParamsAlt.Action := iemwVScroll;
To the demo:
\Demos\Multi\MView_AttachedViewer\MViewPreview.dpr
