set screen background image

[audrieg]

How do you set the screen background image to an image in a sharepoint list where the ID =1

I have a Sharepoint list connection (List name PhotoLinks). It has a hyperlink column (URLLink) formatted as a picture. I'd like to use it as my apps background image. I tried doing what I typed below here - but I keep getting an error message. Can you help fix my expression please?

From the Screen1

Background Image Property

PhotoLinks.URLLink(ID in "1")

The Google URL typed in quotes did work like this:

Background Image: "https://www.google.com/images/branding/googlelogo/1x/googlelogo_color_272x92dp.png"

I don't think there is any "issue" with my image (not sure what you mean there) but let me know if you see any issues here:

-ACCESS ISSUE? I am global administrator on the tenant, and the site collection administrator where the image resides. There are no cases of broken inheritance or IRM

-FILE FORMAT? It is a PNG file which I assume is supported. It opens in all browsers when it is clicked on from the SharePoint Asset Library without issue.

-FILE SIZE? 369 x 586 pixels and 234 kb 

I also went ahead and took mr-dang's advice and created text boxes to show what the two expressions are returning. I think I'll keep a debugger screen from now on (I used to do that in InfoPath too). Here is that that looks like - notice the weird prefix on the urls:

In XL I would  have tried to use the Right() function to remove the prefix:

Right(LookUp(PhotoLinks, ID =1,URLLink),len(LookUp(PhotoLinks,ID =1,URLLink)) - 49)

I tried that (and so the returned value starts with https now), but it still doesn't make the picture show in the background. (Perhaps it needs to be decoded? Argh....)  If this is a bug, and I work around with functions like Right() etc...I'm concerned my app will break when the bug is resolved.

FYI: This effort seemed WAY harder than it should have been to set a background image. Just sayin'

Thank you all for your help!

Hi, I see no issues with the image but with the URL.

Try just directly plugging in the URL with the proper characters as text in the BackgroundImage property of the screen.

Does this work? Does it finally show your picture?

Screen1.BackgroundImage = "https://fullcircletechs.sharepoint.com/sites/Demos/OurPhotos/background.png"

If that works then we can figure out how to get a proper URL 

[audrieg]

I tried it with and without the quotation marks. (without returns error)  I also created an image control and put the same value in it. Neither are showing a picture yet, instead I see "Unexpected token." Oddly enough, when I put copy that path into the browser (without the quotes of course) the picture pops up in the browser as expected.

Hi, I get the same "Unexpected token" error when I do not wrap the URL in quotation marks.  URLs as text should be wrapped in quotation marks.

Did you manage to get Google to be your background image?  Please note the double quotes

You're trying to add an image from a SharePoint library, yes? In this topic, this is the first sentence under Known Issues:

You can add data from a list but not a library.

Does this help?

[audrieg]

So what I did was left the image in the library, but my connection is not to the library - it is to a list that has a title and a URL which I'm mapping to the background.

List fields

Title, ImageURL (URL to linked to a picture in an image library)

Could you explain what you mean by a picture in a list?

Thank you,

Audrie

As a short-term fix, you could just upload the image to the app itself.

1. Download the image that you want to your local computer.
2. In PowerApps, click the Content tab, and then click Media.
3. In the upper-right corner, click Browse.
4. Navigate to the image you want, click it, and then click Open.
5. In the upper-left corner, click the Back arrow, and then set the Background image property of the screen to the file name of the image that you want.
