Hello Rahul,
Unfortunately I'm not sure how to go about reproducing this issue. In our demos if you watch a movie and then hit Play again, the movie will be played once more and there are no issues. The control should behave the same way when playing an audio file. This is why I was wondering if you can send over a sample solution we can take a look at. That will help us better understand your implementation and look for a solution.

Hi Tina,
Can you please provide any sample in which you are playing media file stored in database ?
My Implementation are below:
// DocumentSource is byte array

stream = new MemoryStream(DocumentSource);

Hi Rahul,
If you're using the RadMediaPlayer, then you need to access its MediaElement property. And in order to make sure this property is not null, you can handle the SizeChanged event of the control and set the MediaElement source in it.
I attached a sample solution where the stream of a file is taken from an OpenFileDialog() rather than a database, but the approach is the same. Basically the OpenFileDialog() allows the user to browse for a video file and then takes the stream of the chosen file. Then if the RadMediaPlayer.MediaElement property is initialized (not null), its source is set. Otherwise, the SizeChanged event of the MediaPlayer is handled to apply a source on the MediaElement.
I hope this solution can get you started.

Hi Tina,
I'm having the same problem with RadMediaPlayer: if I choose a file from OpenFileDialog and set it as the MediaElement's source, after file played completely if i click on play button again control is not able to play.
The sample you attached suffers of hte same problem.
I also tried to handle the MediaEnded event and reset the position, but nothing happens.
Any hint to solve this?
Thanks in advance
Paolo

Hello Rahul,
Could give it a try and check whether it works in your case?

I have modified Tina's project and managed to solve the issue.
public
MainPage()
{
InitializeComponent();
}
private
void
xMediaPlayer_SizeChanged(
object
sender, SizeChangedEventArgs e)
{
if
(fileStream !=
null
)
{
this
.xMediaPlayer.MediaElement.Stop();
this
.xMediaPlayer.MediaElement.AutoPlay =
false
;
this
.xMediaPlayer.MediaElement.SetSource(fileStream);
this
.xMediaPlayer.SizeChanged -= xMediaPlayer_SizeChanged;
this
.xMediaPlayer.MediaElement.CurrentStateChanged += MediaElement_CurrentStateChanged;
}
}
Stream fileStream;
private
void
OpenFile(
object
sender, RoutedEventArgs e)
{
OpenFileDialog openFileDialog1 =
new
OpenFileDialog();
if
(openFileDialog1.ShowDialog() ==
true
)
{
this
.fileStream = openFileDialog1.File.OpenRead();
}
this
.xMediaPlayer.Visibility = Visibility.Visible;
if
(
this
.xMediaPlayer.MediaElement !=
null
)
{
this
.xMediaPlayer.MediaElement.Stop();
this
.xMediaPlayer.MediaElement.AutoPlay =
false
;
this
.xMediaPlayer.MediaElement.SetSource(fileStream);
t
his
.xMediaPlayer.MediaElement.CurrentStateChanged += MediaElement_CurrentStateChanged;
}
}
private
void
MediaElement_CurrentStateChanged(
object
sender, RoutedEventArgs e)
{
if
(
this
.xMediaPlayer.MediaElement.CurrentState == MediaElementState.Closed)
{
this
.xMediaPlayer.MediaElement.SetSource(fileStream);
}
}
