Hi,

When I set the text properties say to Bold in my RTB these are not saved to the DB. So when I re-load the RTB from the DB I get the text but not in Bold as I saved it.

Below is the code how I save and re-load the data from and to my RTB.

 

Fist my RTB.

<rad:RadRichTextBox  Name="RTBReceiptFooter" IsReadOnly="False" DocumentContentChanged="TXTPropertyChanged_ReceiptFooter" DocumentInheritsDefaultStyleSettings="True" ShowFormattingSymbols="True" />

Here I grab the text from the RTB in the xaml.cs:

//Export Text

private void TXTPropertyChanged_ReceiptFooter(object sender, EventArgs e)

{

    IDocumentFormatProvider exporter = new TxtFormatProvider();

                using (MemoryStream stream = new MemoryStream())

                {

                    exporter.Export(this.RTBReceiptFooter.Document, stream);

                    stream.Seek(0, SeekOrigin.Begin);

                    StreamReader reader = new StreamReader(stream);

                   

                     _viewModel.MyText = reader.ReadToEnd();

                }

}

Here I get the text from the db in the xaml.cs:

 

_LongDiscriptionSub = _viewModel.MyText;

public void ProvideSubText()

{

    IDocumentFormatProvider provider = new TxtFormatProvider();

            using (var stream = new MemoryStream())

            {

                var writer = new StreamWriter(stream);

                writer.Write(_LongDiscriptionSub);

                writer.Flush();

                stream.Seek(0, SeekOrigin.Begin);

                RTBReceiptFooter.Document = provider.Import(stream);

            }

}
Thanky very much

Hi Wayne,

We noticed you are using TxtFormatProvider to persist RadRichTextBox document. TxtFormatProvider uses txt as underlying format thus it would not persist the rich-text content.

You should use XamlFormatProvider, which on the other hand will persist all document structure (including rich-text formatting, headers/footer, comments, styles and so on) as a Xaml string.

XamlFormatProvider also has APIs that would help you load and save the document directly to a string - to use them you should not cast the provider instance to IDocumentFormatProvider.
