I have a TImageEnMView and TImageEnView.

I can do this with the TImageEnMView to set image indexs for thumbs
to be a bitmap from my imagelist (JVCL TJVImageList)

myTImageEnMView.SetImage(0,Images.Items[0].bitmap);

This works.. but I can't seem to find how to do something like this
with a TImageEnView? I need to be able to load images from list,
and just stuck at a wall here. Know it has to be simple,
but I am at that place of just over looking something now it seems.

There is no specific method to set the image with ImageEnView so just assign its bitmap:
procedure TForm1.Button1Click(Sender: TObject);
var
  iIndex: integer;
begin
   iIndex := StrToInt(Edit1.Text);
   ImageEnView1.Bitmap.Assign(JvImageList1.Items[iIndex].Bitmap);
   ImageEnView1.Update;
end;

or in your case:
ImageEnView1.Bitmap.Assign(JvImageList1.Items[0].Bitmap);

Thanks!

I ended up trying this but did not have the update call.

When you load or assign an image to ImageEnView it is always good practice to call update. It does not slow down your application and ensures the image is displayed.

Thanks William,

Specifically speaking, when loading an image into an ImageEnView (through normal methods) Update will be called automatically.

However you must call Update when modifying the underlying Bitmap/IEBitmap through your own code.
