Features

Capture Mode

The CaptureMode property contains several configuration options for defining the type of user input.
  • Default: The default upload configuration.
  • User: Specifies that the upload operation should show a user-facing camera and microphone.
  • Environment: Specifies that the upload operation should show an environment-facing camera and microphone.
The CaptureMode property works better on mobile devices; if your device is a desktop computer, you'll likely get a typical file picker.

Filter File Types

The AllowedFileTypes property of the Upload control specifies the required media types for file selection.
Some examples include:
  • audio/*: Meaning "any audio file".
  • video/*: Meaning "any video file".
  • image/*: Meaning "any image file".
The file picker with AllowedFileTypes set to "image/*".
The property takes its value as a string containing one or more unique file type specifiers, separated by commas.

Multiple File Selection

When the AllowMultipleFiles property is set to true, more than one file can be selected for upload.
