I am setting GridWidth's value during runtime, but I would like to stretch my TImageEnMView's width to show all the thumbnails. What is the correct way to do this?
Set the GridWidth to -1 to have the thumbnails fill the client area of the component. Of course if the combined widths and height of the thumbnails exceed the client area dimensions then there will be a scrollbar. To show more thumbnails for a given area you need to reduce the thumbnailwidth and thumbnailheight to show all the thumbnails. There are no settings to show all the thumbnails.
