Released: Nov 5, 2025

Updates in v2.3.14

Features

Added API to Determine the Origin of Uploaded Files

• In SurveyJS Form Library, users can upload files using the File Upload and Signature elements. To implement file uploads, you handle the onUploadFiles event.
• This release extends the onUploadFiles event with a new sourceType parameter that specifies the origin of the uploaded file:
  • "file" - The file comes from the user's local file system.
  • "camera" - The file is a photo captured with a device camera.
  • "signature" - The file is an image representing a user's signature.

Fixes

Form Library

• Date input displays both default and custom "min value" error messages simultaneously.
• File Upload: Clicking a file icon opens the file in the same tab instead of downloading it.
• Dropdown with obsolete rendering does not receive focus after a validation error.

Survey Creator

• Slider: Changes to scale labels on the design surface are not persisted and are not rendered in preview.
