Re: Get last removed file name from attachment control

I was able to get this to work using a collection which gets loaded with the attachments on a gallery item select, then if an attachment is removed from the attachments control, using the OnRemoveFile event, I compare the collection I filled previously to whats left in the attachments control and then store the name of the file missing / removed in another collection.

 

The name of my collection to compare is colAttachments


// gallery OnSelect event
If(
    ThisItem.'Has attachments' = true,
    ClearCollect(
        colAttachments,
        ThisItem.Attachments
    );   
    ,
    ClearCollect(
        colAttachments,
        Blank()
    )
);

// Attachments (DataCardValue19) OnRemoveFile event
// stores our removed document
ClearCollect(
    colRemovedAttachments,
    Blank()
);
// loop our originally set colAttachments
ForAll(
    colAttachments,
    If(
        !(colAttachments[@Name] in DataCardValue19.Attachments.Name),
        Collect(
            colRemovedAttachments,
            colAttachments[@Name]
        );
    );   
);
// reset collection for other removals
ClearCollect (
    colAttachments,
    DataCardValue19.Attachments
);
