Power Platform Community Forum Thread Details

I am working on a Power Apps form connected to a SharePoint list. I have a PenInput control used for capturing signatures, and the signatures are saved to a SharePoint image fields (Signature1, 2, 3, 4, 5...)

here is the Update property of the field: PenInput1.Image.

The form is configured in Edit modes (updating on the existing record).

Here’s how the functionality currently behaves:

In Edit Mode: Users can update the signature, and the new signature overwrites the previous one, which is fine. However, if users leave the PenInput blank (don’t sign), the app still updates the SharePoint field with a blank value, overwriting the previous signature.

This is problematic because it results in the loss of the existing signature if the user doesn’t explicitly sign in Edit mode, because my form has 5 signatures, from 5 people, and they are updating their own section in different times, once one of them update his own signature and submit, the others got updated with blank, which is not ok.

I hope it make sense, could you please provide a solution? thank you very much
