Can I force application to load all screens with its content before user can start using it...?

[Lebunim]

Hi all,

Another question/trouble I would like to hear Your input on...

Can I force application to fully load all screens with its content before user can start using it...? 

Each screen has its own background, which is typically 900kb or under 1mgb in size. When I move from screen to screen using Navigate function. The image takes a good 1-2s to load which is a little frustrating, as You get to see all the form controls while image gets loaded. 

So....to the point.... Can I force application to load all screens with its content (including images) before user can start using it...?

Please help...

Hi @Lebunim ，

Where does the background image of your screen come from? Is it a URL?

You could save the images as base64 instead of a URL in your table/list.

Then when you open the app, you could create a collection in the onstart property and save these local images to the collection.

At this point, when you switch to another screen, it will not need to access the URL.
