Thanks for the reply.
Could you clarify a few points:
I'm using RadDocument (not RadFlowDocument) - so presumably there is no DocX format provider I need to use the OpenXml provider. But the only object under the DocX namespace is the DocxExportSettings!
Dim docx As New Telerik.Windows.Documents.FormatProviders.OpenXml.Docx.DocxExportSettings
I have tried using the Xaml format provider but the changes didn't appear when the data was reloaded:
Dim xaml As New Telerik.Windows.Documents.FormatProviders.Xaml.XamlFormatProvider
Dim changes As String = xaml.Export(radDocument)
I'm then saving changes to the database and then reloading when required using this
richTextBox.Document = xaml.Import(changes)
In both cases I have set IsTrackChangesEnabled = True before importing or exporting the text.
I'm currently using the 2016.2.613.45 release for WPF.
Could you provide some guidance.
