Last automn, I have downloaded Telerik.Silverlight.UI.dll (Product version 2007.01.0423.0) and was able to use the RadMediaPlayer from it with great success (in VS2005 since then upgraded to VS2008).
It is an ASP.Net application having a page that host that control. The only thing I have on that page is:
<%@ Page Language="vb"
AutoEventWireup="false"
MasterPageFile="~/MasterPage.Master"
CodeBehind="Interview.aspx.vb"
Inherits="FGLWebSite.Interview"
Title="<%$ Resources:Resources, InterviewTitle %>" %>
<%@ Register Assembly="Telerik.Silverlight.UI" Namespace="Telerik.Silverlight.UI"
TagPrefix="cc1" %>
<asp:Content ID="Content2" ContentPlaceHolderID="objContentPlaceHolderContent" runat="server">
<asp:ScriptManager runat="server">
</asp:ScriptManager>
<cc1:RadMediaPlayer ID="RadMediaPlayer1" runat="server" Height="620px" Width="700px" AutoPlay="True">
<MediaItems>
<cc1:RadMediaItem MediaUrl="/images/dobson.wmv"
Description="John Dobson @ Scully">
</cc1:RadMediaItem>
</MediaItems>
</cc1:RadMediaPlayer>
</asp:Content>
Now (I don't know exactly since when), I have an error when I try to access the page that has the player on it.
When I am in VS2008 SP1, I first have a "Unknown element: Canvas.RenderTransform." error and if click Continue, I have another error raised by IE saying:
Silverlight error message
ErrorCode: 2202
ErrorType: RuntimeError
Message: AG_E_RUNTIME_FINDNAME
MethodName: __ElementId_MouseLeftButtonDownAnimation
After that the viewer is displayed but my video is not loaded.
How can I fix the problem?
