I’m assuming you want some sort of background image for these images seen in this link and to have the background image scroll with these smaller images?
And the images in this link you want them to behave like button’s like for a kiosk app running on touchscreen monitors?
Which would also mean no “ugly” windows scroll bars?
This is probably an idea candidate for a class control, do you also need a thread manager?
Maybe if you spec it out in more detail, you might get some bidding on a class, or might find something coded in another language which could be easily ported?
I dont think you want this Grid Class (Windows.UI.Xaml.Controls) - Windows UWP applications | Microsoft Docs
Layout panels for Windows apps - Windows apps | Microsoft Docs
but maybe you want the functionality seen in this web page with the four smaller images that change opaqueness when the mouse Over occurs?
How To Create a Tab Image Gallery (w3schools.com)
Its hard to tell what exactly you want, I have a few idea’s but could be wrong.
Edit.
So having seen another HTML link
html - Bootstrap Responsive Image Grid - Stack Overflow
I’m beginning to wonder if displaying a webpage might be the quickest way to get what you want, but I dont know if that would work in Anyscreen, as its a web page being rendered in another webpage from what I can tell.
