Getting screen size without specifying the screen

Posted on by dbarnesab

Hi guys, this could be one of those things that's very simple and is just functionality I've not seen so sorry if this is a stupid question:

I'm building apps with a lot of custom dynamic sizing where I am currently using switches and if statements off the back of the screen's size. Example:

Switch(Page1.Size,
    1,Parent.Width-15,
    Parent.Width/4-Self.LayoutGap/2*3-3
)

The problem with this is that I have a large number of screens requiring me to change the screen name within this function each time. Additionally, I'm now starting to need to include these functions within components that are shared across multiple screens. In the example for 'Page1' above, if the same component is used in 'Page2', I now need to create a duplicate component with a 'Page2' equivalent function.

What would be ideal would be if PowerApps had some sort of App level screen size element or the ability to having something like ThisPage.Size but I'm unaware of anything that exists.

Can anyone suggest anything that does exist or a workaround anyone can think of?

Thanks,

Dan

There is also an App.Width and App.Height property that will give you the size of the device screen. If you build the app to be responsive by turning of Scale to Fit in Settings then the App.Width and App.Height will give you the height and width of the screen.

Thank you @Pstork1, that's perfect! I did say it's probably basic functionality that I've missed!

I can now do something like this:

If(App.Width>1200,Parent.Width/4-Self.LayoutGap/2*3-3, If(App.Width>800,Parent.Width/4-Self.LayoutGap/2*3-3, Parent.Width-15 ) )

Combining the built in screen sizing (1,2,3 & 4) with the pixel output of this may be tricky but manual values of 1200, 800 etc. as above will work fine.
