Power Platform Community Forum Thread Details

Hi everyone,

I’m working on a Power App with a SharePoint list as the data source. The list contains location records, each with an Image column (LocationPhoto).

In my Gallery (GalleryLocations), I want to:

Show a placeholder image when there’s no photo yet.
If a photo already exists, display it in the gallery.
Allow the user to upload or take a new photo and have it replace the existing photo for that gallery item.

What I tried:

Patch(
Locations,
GalleryLocations.Selected,
{ LocationPhoto: AddMediaWithImage.Media }
)

But this gives errors like “LocationPhoto does not meet record type” or Power Apps expects a resettable control as input.

I also tried using variables, JSON(), and Reset(AddMediaWithImage), but still can’t get it to replace the existing image.

Question:

What is the correct approach to:

Show a placeholder image in the gallery if no photo exists.
Upload/take a new photo from AddMediaWithImage and replace/update the LocationPhoto in the selected SharePoint record?

Any working examples or best practice patterns would be very helpful.

Hi @ryb,

Firstly upload your placeholder image to your Media - I will call it PlaceHolder below and then on your Image control in the Gallery (assuming you have a seperate Image control) add to the Image property.

Coalesce(
   ThisItem.LocationPhoto.Large,
   PlaceHolder
)

If you want to do the whole thing on the AddMediaWithImage control, make the Image of the UploadedImage control

Coalesce(
   AddMediaButton.Media,
   ThisItem.LocationPhoto.Medium,
   PlaceHolder
)

You may also need to reduce the font size of the button.

Next your Patch

Patch(
   Locations,
   LookUp(
      Locations,
      ID = GalleryLocations.Selected.ID
   ),
   {LocationPhoto: UploadedImage.Image}
)
