Hi Community,
I am new to power pages.

Background:
I have integrated SharePoint into my dynamics 365 portal.
I have a business req, where if a field is empty, then user should upload at least one file.
Hence, I want to make the upload file field as mandatory.

Question:
As Sharepoint grid is not connected to an entity, I am not sure, How can I do it?

Any help is appreciated.

Hi @PaulMatha,

it's a bit difficult to exactly understand where and what you want to achieve, but generally you can set up a form with an attachment field and make that one mandatory. If you are using it in power pages and it should be mandatory on conditions you will need to add javascript and for the * some css :before. As Business rules are not applied in power pages as far as I know.

For the attachment I find that tutorial quiet helpful: Link for Tutorial
