Expression,
Futuristic,
Professional,
Simple
}
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
MediaPlayer1.AutoPlay = true;
MediaPlayer1.ScaleMode = System.Web.UI.SilverlightControls.ScaleMode.Zoom;
cmbSkins.Items.Add(MediaPlayerSkins.Classic.ToString());
cmbSkins.Items.Add(MediaPlayerSkins.Console.ToString());
cmbSkins.Items.Add(MediaPlayerSkins.Expression.ToString());
cmbSkins.Items.Add(MediaPlayerSkins.Futuristic.ToString());
cmbSkins.Items.Add(MediaPlayerSkins.Professional.ToString());
cmbSkins.Items.Add(MediaPlayerSkins.AudioGray.ToString());
cmbSkins.Items.Add(MediaPlayerSkins.Simple.ToString());
cmbSkins.AutoPostBack = true;
cmbSkins.SelectedIndex = 4;
MediaPlayer1.Med开发者_如何转开发iaSource = Server.MapPath("~/") + "Wildlife.wmv";
xx.InnerHtml = Server.MapPath("~/") + "Wildlife.wmv";
MediaPlayer1.MediaSkinSource = "~/MediaPlayerSkins/" + cmbSkins.SelectedValue + ".xaml";
}
}
protected void cmbSkins_SelectedIndexChanged(object sender, EventArgs e)
{
MediaPlayer1.MediaSkinSource = "~/MediaPlayerSkins/" + cmbSkins.SelectedValue + ".xaml";
}
}
I don't know anything about Silverlight and this is done using a article, I only changed the source of player nothing else and this is not working.
One question is arising in my mind that which is the best for playing video flash player or this one while we have a low bandwidth internet connection. Please tell me some useful solution?
Thanks
To answer this part of your question:
tell me what is the difference between media element and media player in silver light.
The MediaPlayer element you've used is an ASP.NET control which consists of a basic Silverlight player (using Silveright 1.0 I think). All you have to do is point it at the video file and it will play. The MediaPlayer gives you all the basic controls for playing media (play/pause, etc).
A MediaElement is a Silverlight type used in a Silverlight application, not an ASP.NET application like the MediaPlayer. MediaElements are used in XAML (i.e. Silverlight markup) to represent, well, media elements. The MediaElement doesn't give you controls for playing the media, it just renders it (whether audio or visual). You can use other elements in XAML to control the MediaElement, e.g. if you wanted a play/pause button, you could create another element to do that.
guys i found why it was not working i am missing the proper source path that should be "~/MediaFile.wmv" instead of server.mappath(....).
