Posted on by Dca2

Hi all,

I created an App in PowerApps using a Dataverse database in my Teams environment. I need to be able to attach documents in the App, so I added the Attachment Control from a form. I am able to click on it, the file explore window comes up I am able to select a file and upload it successfully. I can see the file in the Attachment Control window, but it says “Unsaved” could you please help me?

Hi. If this is a form and its in Edit mode, have you done a Patch or a form submit to save it?
If not its just in the UI not in the back end.

You need to click whatever you do now, to update your Form values in the back end. And I also assume the control is ON your form.

If you like my answer, I would really appreciate if you please Mark it as Resolved, and give it a thumbs up, so it can help others

Cheers

Thank You

Hi Mike, I think you are right is just in the UI not in the back end. I have not done a patch or form submit because I don’t know how. This is my very first App 😁 Could you please briefly tell me what I need to do? Thank you

Hi @Dca2,

Have you solved your problem?

Do you want to save attachments to Dataverse table?

If so, there is a lot of preparation work to be done:

1). You need to create a dataverse table with a custom column named AttachFile. When you create a table with file type columns, make sure to check “Enable Attachments (including notes and files”).

2). After that, create a column inside that table with data type File so that it can only store file attachments:

3). Now we are done with the table, let’s move on to the canvas app, keep your attachment control and add a save button, set its OnSelect as:

Patch(TableName,Defaults(TableName),{AttachedFile:{FileName:First(DataCardValue3_1.Attachments).Name, Value:First(DataCardValue3_1.Attachments).Value}})
