Gets a value that indicates the current buffering progress.
The amount of buffering that is completed for media content. The value ranges from 0 to 1. Multiply by 100 to obtain a percentage.
This property is read-only. The default value is 0.
The BufferingProgressChanged event occurs whenever the BufferingProgress property is updated by 0.05 or more, or reaches 1.0.
In some cases, the BufferingProgress value does not remain at 1 as the media plays.
