Creating a RadDocument from XAML string

[Patrick]

I have a XAMLDataProvider that is binding a string property to a RadRichTextBox.

I want to be able to bind the content of the RadRichTextBox to a string (which I have done) and then once a save button is pressed, I need to run some code similar to this.

Telerik.Windows.Documents.FormatProviders.OpenXml.Docx.DocxFormatProvider provider = new Telerik.Windows.Documents.FormatProviders.OpenXml.Docx.DocxFormatProvider();
RadDocument document = new RadDocument(string myXAMLString);
byte[] output = provider.Export(document);

Essentially I need to be able to bind a property from the ViewModel to RadRichTextBox..... which I am doing with XAML data provider.

Then after a save button is clicked, I take the property which is a string and I need to create a RadDocument from the string that represents that and export that document to a byte[].

Is there an easier and better way to be doing this?

Thanks!

Hello Patrick,

The XamlFormatProvider class does not provide such an option via its export functionality. You could use its Export method, which returns a string value from a passed RadDocument instance. You could retrieve the RadDocument of the RadRichTextBox control when clicking on the save button and pass it to the Export method. Then, you could convert the returned string value to a byte array as shown in the following StackOverflow article:

Could you give this suggestion a try?

I ended up using XamlFormatProvider to import my string into a RadDocument. I then took the DocxFormatProvider and exported myRadDocument into a byte [].

This allowed me to achieve my desired results.

You can achieve this by using the built-in Load method of RadDocument class that accepts a string argument. Here's the simplified code:

byte[] output;
using (var memoryStream = new MemoryStream(Encoding.UTF8.GetBytes(myXAMLString)))
{
  RadDocument document = RadDocument.Load(memoryStream);
  // rest of your export logic using provider.Export(document)
}

This approach avoids creating a separate RadRichTextBox instance and leverages the RadDocument's loading capabilities directly from your XAML string.
