Hi,

I use a RichTextBox with RibbonUI, in which I added a new RibbonButton with a command to add a InlineUIContainer at the current text position. The InlineUIContainer is filled with a RadMediaPlayer.

RadMediaItem rmi = new RadMediaItem();

rmi.Source = new Uri(Application.Current.Host.Source, "../Resources/Videos/Wildlife.wmv");

RadMediaPlayer rmp = new RadMediaPlayer();

rmp.Items.Add (rmi);

Telerik.Windows.Documents.Model.InlineUIContainer container = new Telerik.Windows.Documents.Model.InlineUIContainer()

container.UiElement = rmp;

if (size != Size.Empty)

{

container.Height = size.Height;

container.Width = size.Width;

}

After filling the InlineContainer the command inserts it into the RichTextBox document using an "InsertInline(container)" call.
This works fine and I get the MediaPlayer at the destined position within the document.
If I now save the documents content - close and reopen the RichTextBox - the document stays empty (because of an error when loading the document data (XAMLFormatProvider)).
The reason for that is, that the RichTextBox "automatically" has added a Canvas.Top and Canvas.Left assignment within the RichTextBox xaml line in the InlineContainer paragraph:
<telerik:RadMediaPlayer Clip=... Canvas.Left="2" Canvas.Top="70,7242660522461">
If I manually delete this Canvas assignments in the xaml code the document gets loaded and the RichTextBox workes fine again.

Can one help me?

Kind Regards
Alois

Hi Alois,

I did some testing and it seems that the problem is with the Position property of RadMediaPlayer. The issue has been reported before and you can find an explanation and a possible workaround in this forum thread. There is also a PITS issue, which you can use to track our progress on the issue and increase its priority.
