Hello Power Apps Community,

I have a Power Apps form connected to a SPO list that contains attachment control.

The display name of the attachment needs to be renamed based on the selection made by the user on a dropdown list so I´m working with a collection in order to accomplish this.

The issue I am facing that once I submit the form with the attachment, then if I open this item in edit mode & remove the previous attachment and upload another one with the same name and submitting, the old/previous attachment is the one that remains not the new one.

I need to either be able to remove the attachment with the X or overwritte the attached document when another one with the same display name is uploaded and the form is submitted. This is the collection I´m using on the OnAddFile Property of the attachment control:

Set(varExtension,Find(".",Last(attachCedula.Attachments).Name));
Set(varExtension2,Mid(Last(attachCedula.Attachments).Name,varExtension));
ClearCollect(
    colCedulaAttachs,
    attachCedula.Attachments
);
UpdateIf(
    colCedulaAttachs,
    !StartsWith (DisplayName,DataCardValueCed_Exp.Text),
    {
        Name: DataCardValueCed_Exp.Text & "-" & DataCardValue_CodReq.Text & varExtension2,
        DisplayName: DataCardValueCed_Exp.Text & "-" & DataCardValue_CodReq.Text & varExtension2
    }
);
RemoveIf(
    colExpedienteAttachments,
    DataCardValueCed_Exp.Text in DisplayName
);
Collect(
    colCedulaAttachs,
    colExpedienteAttachments
    
    
);

As you can see it is not removing the files. I´ve tried adding another collection called "colExpedienteAttachments" but to no avail.

On the OnRemovefile and OnUndoRemoveFile I´ve got "false".

Please help.

Thanks.

Hi @AlexBS

The fundamental issue here is that the only way in Power Apps (excluding Power Automate) of adding the actual file content is with the attachment control itself. You can do all the file name manipulation as you are presently, but if you have a look in the collection, the Value field is a BLOB (Binary Large Object) reference that can only be changed/added by the control.
