Hello Michael,

After some research our developers said that the issue comes from the adobe reader since with the latest version of adobe reader they weren't able to reproduce this, so I can suggest you update your adobe reader. If this doesn't help you could you please send us a sample where this is reproduced and the versions of your browser, SL, OS, adobe reader and NetAdvantage, so we could investigate this further?

Looking forward for your reply.

Hi Krasimir,

It will be difficult for me to strip down our big application but I believe it has to do with adobe X. In adobe 9 the control works fine. I have a screenshot but this post does not allow me to paste or attach anything.

We have setup our xaml and code as follows:

 XAML

------------------------------------------------------

 <ig:XamHtmlViewer SourceUri="{Binding AttachmentUri}"  Grid.Row="1" Grid.Column="0" Grid.ColumnSpan="3" Visibility="{Binding IsViewerVisible}"  Margin="3" HorizontalAlignment="Stretch" HorizontalContentAlignment="Stretch" VerticalAlignment="Stretch"  VerticalContentAlignment="Stretch"/>

VIEW MODEL

------------------------------------------------------

private Uri _attachmentUri; public Uri AttachmentUri {     get { return _attachmentUri; }     set     {         _attachmentUri = value;     } }

And we just assign the AttachmentUri everytime the user clicks on an item on a list.

Michael
