(1) Share

Posted on by KristyH

Hi Team

I have a PowerApp made which collects data through forms. I want the users to be able to upload documents to Sharepoint when completing this form.

I have the upload section working via a button inside the Attachment DataCard, and a PowerAutomate flow.

 
OnSelect for Upload Button:
ForAll(
    attach.Attachments,
   Uploadfiletosharepoint.Run(
        {
            file: {
                name: ThisRecord.Name,
                contentBytes: ThisRecord.Value
            }
        }
    )
)
 
I have also made a flow in PowerApps for the deleting of the sharepoint file, inside a Gallery, inside the Attachment DataCard.  However, i am having trouple with getting the OnSelect for Delete Button, working correctly.
 
 
This is the Delete Attachment PowerAutomate within PowerApps:
Not sure if i'm missing anything here.

Hi, no, it doesn't answer my question at all.

I asked specifically about the OnSelect for the delete button to make the flow work.

so if i did change the flow to Delete Attachment instead, i am still unsure about the coding on the OnSelect button.

Hi KristyH

Just be aware I am not aware of your coding level/skills, so many times pointing people in the right direction works without further comment works and if not, I assume they will come back for further clarification.

This one however is far from straight forward when I did some testing. You need to send at least two parameters to the Flow - the ID of the record and the name of the attachment. I have hard-coded the site and list names, but you could also send them if you want to make this Flow generic.

The Flow looks like this - I have tested it and can confirm it works - you may need a refresh of the data source afterwards to display the changes.

Just following up to see if you received the answer you needed, or if you require further assistance.

HI

I am super confused, based on your response to Warren. You are in fact deleting the item (or you want too), in the flow, so why would what Warren said, somehow not answer your questions.

You are NOT deleting it in the App... but you also have to be careful with wording. You said you want to upload files, thats not exactly true. You ant to attach files, uploading them means putting them in a Document library.

So you cannot simply delete it like its in a library, if you actually made it an Attachment when you created it. Since you are using the Attachment control, we have to assume you are.

To then delete the Attached(not uploaded file), you have to do what Warren said.

You should really be more respectful when you don't know what you are saying. Warren answered exactly how its done so it 'DOES answer your question.
