How to delete just a single Attachment in a SP List

Posted on by vDaddy78

My app currently deletes all attachments from a SharePoint list row. I need to be able to just delete the selected attachment. The code I'm using currently is:

Remove([@AssessmentList], GalleryAttachmentList.Selected)

which deletes all the attachments

Any help will be appreciated.

Actually, the code provided deletes the entire List entry not just the attachments.

Hi @vDaddy78 ,

Could you please share more details about your scenario? What's the Items property of the Gallery you mentioned?

I made a demo for your reference:

Flow is quite simple:

Both input parameters are "Ask in PowerApps" from dynamic content, if you cannot find it, click "See more".

Button OnSelect:

ForAll(ListBox1.SelectedItems, 'PowerApp->Deleteattachment'.Run(ThisItem.ID,Id));Refresh(AssessmentList)

Best regards,

I made a change in the app to where they are only able to load a single attachment per row in the list. They have to remove the current attachment before being able to load a new one. I remove the current attachment using the Patch Form.Update

Thank you for the help though.
