RichTextBox content to xaml in memory stream

[Edo Cof]

                IDocumentFormatProvider exporter = new XamlFormatProvider();
                MemoryStream output = new MemoryStream();
                exporter.Export(this.editor.Document, output);
                StreamReader stream = new StreamReader(output);
                return stream.ReadToEnd();

I try this way, but after Export called, i check ouput variable and get error: Cannot access a closed Stream for every property that Stream has.
I want to store xaml in database, and the best way is to store it with RIA in mssql Text field (i think).

Hi Edo Cof,

We are very glad you decided to give a spin of our new control. 

Currently the Export method of the XamlFormatProvider class disposes the output stream that it takes as a parameter. This is a known issue and will be fixed in the next release. For now we can suggest a temporary workaround by using a custom StringStream class. Here is a snippet for getting the XAML content of the document:

IDocumentFormatProvider exporter = new XamlFormatProvider();
string result;

using (StringStream output = new StringStream())
{
    exporter.Export(document, output);
    result = output.Value;
}

return result;

Please find the StringStream class in the attached .zip file.
Let us know if you need further assistance.

Is there a typo here?

 public string Value

        {

            get

            {

                return this.value;

            }

        }

should it actually be

public string Value

        {

            get

            {

                PrepareValue();

                return this.value;

            }

        }

otherwise the this.value doesn't get set first

Hello Malcolm,

The purpose of the code we posted several months ago was to workaround an issue related XamlFormatProvider closing the output stream. This problem has been fixed in Q2 version and you would no longer need to use this helper class. Let us know if this helps.

Sincerely yours,
