Persist TrackChanges

[Andrew]

Is it possible to save a RadRichTextBox RadDocument with IsTrackChangesEnabled so that it can be reloaded and the changes still be visible?

I need to save the document to a database (or file system) and then load it on a different PC/user later on for review.

I presume it needs to be Exported using a FormatProvider - but can't find any documentation detailing the steps.

Thanks

Hi Andrew,

You are right - you will need to save the document using a format provider and reload it back to show in a different machine/application. You can find information on how to use the different format providers of RadRichTextBox in the Import/Export section of the documentation. Note that the track changes are currently preserved only when exporting to DOCX and XAML. Would these formats suit your needs?

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.

Thanks

Hi Andrew,

The namespace you are using is the correct one and you should be able to use the DocxFormatProvider of RadRichTextBox.

I created a sample project to demonstrate the functionality. In this sample, a new RadDocument instance is created and the content is modified while the Track Changes is enabled. The content with the revisions is then exported to XAML and to DOCX using the respective providers. I tested importing back both documents and everything seems to be working as expected. Could you please test it on your end as well and let me know how it works for you?
