How to I change the DisplayName of an image attachment by simply clicking on it in Power Apps?

Posted on by powaya

In my Power App I have a gallery of image attachments that is pulled from a Sharepoint list. I want the user to be able to change the name of an image attachment to "TestImage" just by clicking on the image name as you see in the screenshot below. I tried achieving this by setting the DisplayName to "TestImage" in the OnSelect code of the image label. But as you can see, that is causing an invalid arguments error. How do I allow the user to change the name of an image attachment by simply clicking on it in Power Apps?

Set(ThisItem.DisplayName,"TestImage");

Hi @powaya ,

You cannot do this - it is the name of the underlying file (which is actually stored in OneDrive).

@WarrenBelz But the underlying file attachment is stored in Sharepoint, not OneDrive, and I was able to give the attachment an initial name using PowerApps, so shouldn't there be a way to rename the attachment too?

@powaya ,

The file is actually in OneDrive (but that is probably not relevant) with a List attachment or are your talking about a SharePoint Library here?

An Attachment Control (which is the only way in Power Apps to add or delete attachments) does not have a rename function. Also you did not give it an initial name - it would have taken the name of the file uploaded. Power Automate can add or delete attachments, but not rename them.

If this is a Library, you can do it in a Grid View in SharePoint, but any attempt to Patch it from Power Apps states the field is read-only.

@WarrenBelz Yes the image file is uploaded to a Sharepoint List as an attachment to one of the rows in the list. The power apps code that is used to add the attachment is below. This code allows the power app user to enter a custom image name into a text box input, and the file takes that DisplayName. So I'm wondering, if power apps can assign a DisplayName to an attachment, why can't it rename an attachment as well? That seems kind of odd no?

Collect( colImages, { DisplayName: ImageTextInput.Text & ".jpg", Id: ImageTextInput.Text & ".jpg", Value: Camera1.Photo } );

@powaya ,

Firstly, that code does not attach anything to a List - it is putting the images from the camera in a collection. I assume you have a Flow that runs after that and attaches the items to the desired List record. You did not mention a Camera image before and I naturally assumed you used an attachment control (and therefore no Flow involved), however back to your question - you cannot rename attachments once they are stored on a list item.
