Posted on by Rajua 14
Hi ,
 
  I have a gallery grid with 9 columns one of them is attachment, which i copied the data cards value of the form and added it here, in this when i try to add file i am able to add files the challenge is i am not able to save to share point and make it appear in added attachments. My expectation is when i click on the submit button along with the other datas, attachment file should get saved into the sharepoint and also in the attachment add files of gallery. Below is my current patch data in submit button
 
Patch(
       Datasource,ThisItem,{column values to patch}
);

    Hi,
     
    The issue is that attachments don't get saved automatically when using Patch() the way they do with a SharePoint form and SubmitForm(). The attachment control only stores the files locally until they're explicitly submitted.
     
    If you're patching records from a gallery, you'll need to either:
    • Use a SharePoint form and SubmitForm() to handle attachments automatically, or
    • Create/update the item first with Patch(), then use a Power Automate flow to upload the attachment(s) to the SharePoint item.
     
    The SharePoint Attachments column cannot be patched with just the other field values. That's why your record saves but the attachment doesn't appear afterward.
     
    A common pattern is:
    1. Patch() the SharePoint item and capture the returned ID.
    2. Pass the attachment content and item ID to a Power Automate flow.
    3. Use the flow to add the attachment to the SharePoint list item.
    4. Refresh the data source so the attachment appears in the gallery.
    If you're using an Attachments control inside a gallery, that's another challenge, as the control is primarily designed to work within an Edit Form. I'd recommend using a flow-based approach for the attachment upload in this scenario.
     
    Thanks & Regards,
