Hi

I am trying to use TImageEnMView to display the images resulting from a query from a Firebird database. I haven't found a way to bind or get the primary key (database primary key field) of the selected images (EnableMultiSelect: = true) for processing.

Regards,

Alfonso



Hi

You can use SetActiveImage to position the database at a record, and then read directly from the database, e.g.

// Read a database field for all selected images in a TImageEnMView add add to a TMemo
var
  i, selIndex: Integer;
begin
  memo1.Clear;
  for i := 0 to ImageEnMView1.MultiSelectedImagesCount - 1 do
  begin
    selIndex := ImageEnMView1.MultiSelectedImages[ i ];
    ImageEnMView1.IEMBitmap.SetActiveImage( selIndex );
    memo1.Lines.Add( qryImages.FieldByName( 'Image_ID' ).AsString );
  end;
end;
