Hi,

I am using the XamRichTextEditor in an XamGrid TemplateColumn and i have problems by comparing the richtextdocument. What i want to achieve is that if a user clicks in the cell and updates something in the XamRichTextEditor document i want to save the new version in the database. 

I have the following xaml column configuration:

                            HorizontalContentAlignment="Stretch" VerticalContentAlignment="Stretch" >

       
           
                                                              ClipboardOperationExecuting="DescriptionEditor_OnClipboardOperationExecuting"
                                              GotFocus="DescriptionEditor_OnGotFocus"LostFocus="DescriptionEditor_OnLostFocus" Height="Auto"/>
                                                                 RefreshTrigger="Delayed" DelayAfterLastEdit="00:00:01.00" Visibility="Collapsed"
                                                 Value="{Binding Document}"/>
           
       
   

I have handled the following two events for this:

1) OnGotFocus -> Here i am saving the current RTF document to a stream by using the SaveToRtf method

2) OnLostFocus -> Her i am saving the new/updated RTF document to a stream by using the SaveToRtf method

The problem is now that if the user doesn't change anything i also get differences betweent the two streams. Why is that? Whats the Problem here?

How can i check if two rtf documents are equal? And how can i check if an document is empty?

Also if i "Export Content" from the Samples Browser i get different output and cannot compare two rtf documents.

Thanks in Advance!

Best Regards 

Rene
