Signature

  • Last UpdatedJun 25, 2024

Use Signature control to capture a user’s signature in a form by drawing on a touch enabled device. The signature is rendered as a picture and shown to the user in edit mode of the form (i.e. before save or submit). The Signature is saved in an encrypted format after the form is saved or submitted. The user cannot edit the saved signature, but has the option to undo/clear the Signature before the form is saved or submitted.

This control works across browsers in web and via the Work Tasks Pro app.
