Issue with InlineUIContainer within RichTextBox

[Alois]

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.

Kind regards,

Hi Ivailo,

I'm now using the workaround you mentioned.
Just a hint: In my case I have to delete the Canvas.Left and Canvas.Top properties within the document to be successful. There is no Position property in the document to be cleared.

Thank you for your help!

Kind regards
Alois
