Thanks a ton for your reply. That did get rid of errors that I was having.
The page displays, and I put borders around the richtextbox control so that I could see it.
BUT, the richtextbox is empty, no text displays.
This is the line with the filename:
webClient.OpenReadAsync(New Uri("guidelines.docx", UriKind.Relative))
I know that file exists. Do I need to qualify it more with some other kind of path details?
The only other difference I see is that your code "Inherits UserControl" and mine "Inherits Page" because I'm using navigation pages.
That wouldn't matter would it?
Does anything need to change in the .xaml?
Here's my declaration for the richtextbox control:
<telerik:RadRichTextBox Name="radRichTextBox1" Width="700" Background="White" BorderThickness="1" BorderBrush="Black" IsReadOnly="True" />
Thanks again, a ton, for your help!
