Displaying list of attachments from datacard in a gallery - Power App formon SPO list

[jster24]

I am using the "Customize form with Power Apps" feature on a SharePoint list. I would like to display thumbnail images of the attachments, in a gallery, from the item that is displayed on the form. I have successfully done similar things to this, with nesting galleries and displaying thumbnails in a a full Power App. Perhaps I am not grabbing the right idea for these forms though. I don't have a gallery to display from, I don't seem to be able to use the gallery within the item form itself, and I'm not exactly sure how I would execute this. 

I have created three screens, in this form customisation. Create Screen with CreateItemForm, EditScreen with EditItemForm, and ViewScreen with ViewItemForm. I'd like to put the gallery on both the EditScreen, and ViewScreen. 

Anyone have ideas on how i could do this?

@WarrenBelz , funnily enough I still have your site open in another tab. I had seen your examples and examples like this from others in my search before submitting to asking for help. It seems this may not work, or I don't work?!

Hi @jster24 ,

Is that Gallery inside or outside the form? If inside, you just need ThisItems.Attachments as the Gallery Items and ThisItem.Value as the Image of the Image control.

@WarrenBelz , it seems whenever I have the item form selected, and try to insert a Gallery inside of it, it places it outside of the form, on a separate layer. Which may be a fun/not fun feature and difference in Power App form customisation vs a full Power App?

@jster24 ,

You have to unlock the card and select an item in it before adding the gallery, however you can display the gallery outside. Assuming the record in the form is selected from another gallery, you can have the Items of the image gallery as

Lookup(
   ListName,
   ID = OtherGalleryName.Selected.ID
).Attachments

and then the Image the same

ThisItem.Value

If you just want to display one attachment (no gallery here, just an image control)

First(
   Lookup(
      ListName,
      ID = OtherGalleryName.Selected.ID
   ).Attachments
).Value

Yup, just double checked both the data cards are unlocked, and it will still not let me insert a gallery into the card. It puts it in it's own layer. I also tried to create a custom card and insert the gallery but no dice. This SharePoint list form isn't based off of another gallery, just the selected item on the list.

@jster24 ,

It might seem a bit counter-intuitive, but I found this always works - add a gallery to the screen, then select and Ctrl-x (cut), select the unlocked card and Ctrl-v (paste). Also if you want it outside the form, it can have the Items

Lookup(
   ListName,
   ID = SharePointIntegration.SelectedListItemID
).Attachments

Just tried this and you were absolutely right. Cutting the already added Gallery and pasting in the data card worked. Definitely a smh at myself moment! Thank you for sticking with me!
