Why Attachments Might Be Missing. Here are the most common reasons attachments don't appear on Power Pages forms:
1. The Attachment Column is a File or Image Column
Power Pages does not support File or Image columns on forms directly out-of-the-box.
These columns show on model-driven forms but won’t render on the portal.
Fix: Use Notes (Annotation entity) instead.
2. You Haven’t Enabled Attachments on the Form Metadata
To enable attachments on a Power Pages form:
Go to Power Pages Studio or Portal Management App
Open the Basic Form (now called Form under Pages)
Under the “Attachments” section:
✅ Set Enable Attachments = Yes
✅ Set the appropriate Entity Name (usually annotation)
✅ Optionally, restrict file types or size
3. The Form Isn’t Using the Notes Control
If you're not using Notes (a subgrid of annotations), then attachments don’t appear.
Use a Notes section on your form:
Open your form in the model-driven app (table form designer)
Add a Timeline control (not just a field)
Enable Notes, and within that control:
Allow file attachments
Save and publish
4. Permissions on the Table: Double-check that the user’s web role has Create/Read/Write access to the file column via table permissions in your site’s security configuration.
5. Enable Attachments for the Table (if using Notes): If you're using notes for attachments instead of file columns, make sure the table has "Enable attachments (including notes and files)" turned on in the table settings.
For Signature
If you're also capturing a signature, the native Power Pages form does not have a signature field. Workarounds:
Use a Canvas App embedded in an iframe to capture signature
Or use a custom JavaScript component with a <canvas> element for drawing and submit it as a base64 image to a field
