MediaControl.SoundLevelChanged | soundlevelchanged event

Applies to Windows only

[MediaControl may be altered or unavailable for releases after Windows 8.1. Instead, use SystemMediaTransportControls.]

Event raised when the sound level changes.

Syntax

Public Shared Event SoundLevelChanged As EventHandler(Of Object)

Event information

DelegateEventHandler [JavaScript] | System.EventHandler<Object> [.NET] | Windows.Foundation.EventHandler<Object> [C++]

Remarks

Here is a JavaScript code snippet that shows how to add event listeners to a MediaControl object. It then shows how to write code to handle some of those events. The code snippet assumes that there is a corresponding HTML file that contains an <audio> tag, with its element ID set to "audiotag."


// Assign the Windows.Media.MediaControl button object to 
// the user-defined mediaControls variable
mediaControls = Windows.Media.MediaControl;

// Add event listeners for the buttons
mediaControls.addEventListener(“PlayPressed”, play, false);
mediaControls.addEventListener(“PausePressed”, pause, false);
mediaControls.addEventListener(“PlayPauseTogglePressed”, playpausetoggle, false);
mediaControls.addEventListener(“NextTrackPressed”, nexttrack, false);
mediaControls.addEventListener(“PreviousTrackPressed”, previoustrack, false);
mediaControls.addEventListener(“SoundLevelChanged”, soundlevelchanged, false);

// Add code for event handlers for the events
   function play() {
	     document.getElementById(“audiotag”).play();
   }

   function pause() {
	     document.getElementById(“audiotag”).pause();
   }

   function playpausetoggle() {
      //<code goes here to handle the PlayPauseToggle event> 
   }
   
   ...
   // Additional code to handle the other events
   // For example, add event handler code for the following events:
   // NextTrackPressed
   // PreviousTrackPressed
   // SoundLevelChanged
