Hi @CU04011210-0

Let's utilize the DisplayMode property, every control in Power Apps has a DisplayMode property. You can leverage this to switch between View and Edit.

For your Attachment control:

DisplayMode = If(FormMode = FormMode.View, DisplayMode.View, DisplayMode.Edit)

When the form is in View mode, attachments are shown but cannot be modified.

When the form is in Edit mode, users can upload new attachments.

I am sure some clues I tried to give. If these clues help to resolve the issue brought you by here, please don't forget to check the box Does this answer your question? At the same time, I am pretty sure you have liked the response!

Hi @CU04011210-0,

Set the Attachments control to inherit the form’s mode.

Put the Attachments card inside your form, unlock it if needed.

Set Attachments.DisplayMode = Parent.DisplayMode

Switch modes with ViewForm(FormName) for read-only (shows existing files) and EditForm(FormName) for add/remove; save with SubmitForm(FormName).

check also the Sources if more info needed:

Hi @CU04011210-0,

I think you should use two controls and toggle DisplayMode for this. Canvas Attachment control cannot show existing files in View mode while allowing new uploads in the same control, so the according to me the pattern should be like:

View Mode → Existing attachments shown in gallery. Edit Mode → Attachment control enabled for uploading new files.

1. Attachment control (for upload)
Formula: DisplayMode = If(ViewMode, DisplayMode.Disabled, DisplayMode.Edit)

2. Gallery / Data table (to show existing attachments)
Items = Attachments from the record (SharePoint / Dataverse). Visible only in View mode.

Upload Attachment Control

DisplayMode = If(varFormMode="View", DisplayMode.Disabled, DisplayMode.Edit)

Gallery to show uploaded files
Items = ThisItem.Attachments Visible = varFormMode="View"

Reference: Attachment control limitations(https://learn.microsoft.com/en-us/power-apps/maker/canvas-apps/controls/control-attachments)

I hope this works for you!

Hello @CU04011210-0,

If the Attachment control is already inside the form, you usually don’t need to add any condition for View or Edit mode because it automatically follows the form mode.

If the goal is to separate already uploaded attachments from new ones in Edit mode, one simple approach is to show the existing attachments in a Gallery inside the same DataCard so users can easily view them, and keep the Attachment control for uploading new files.

Add attachment control inside the Attachment DataCard.

Attachment Control Items Property:

Parent.Default

Gallery Item Property:

ThisItem.Attachments

Gallery Visible Condition: (On Visible Property)

ThisItem.'Has attachments'

Gallery Hight Property:

Self.AllItemsCount*Self.TemplateHeight

This makes it clearer for users because they can see the previously uploaded files separately and still use the attachment control to add new ones.
