I cannot access richTextBox1.Document which I need for storing into db

Question

I have a Windows Form (.NET Framework) with a rich text box and I want to store its data to a database. Through my research, the code I found was:

string rtfText; //string to save to db
TextRange tr = new TextRange(richTextBox.Document.ContentStart, richTextBox.Document.ContentEnd);
using (MemoryStream ms = new MemoryStream())
{
tr.Save(ms, DataFormats.Rtf);
rtfText = Encoding.ASCII.GetString(ms.ToArray());
}

When I try to add line 2 to my code, I get to richTexBox. but Document cannot be found when I type it.

Now when I added a reference, I selected PresentationFramework, and at the top of my code, added the line:

using System.Windows.Documents;
using System.Windows.Controls;

and I still cannot access richTextBox1.Document. I'm using Visual Stusio 2019 and am using .NET Framework 4.7.2.

How can I access richTextBox.Document?

Thanks for the help,

have you tried rtf property??? string s = richTextBox.Rtf; it should give you all formatted text

Have a reference of the below article for saving the rtf with formatting https://nishantrana.me/2007/11/03/saving-richtextbox-control%E2%80%99s-content-rtf-file-in-database/

System.Windows.Forms.RichTextBox doesn't have document property , you are taking about wpf's System.Windows.Controls.RichTextBox which have document property. in windows forms to get richtextbox value you can directly use var text=richtextbox1.Text

Thank you. I do have the namespace using System.Windows.Controls; in my code but it still isn't working. Is there a specific reference I have to add?

in my Windows app, I have a rich text box. What I want to do is store the rich text box content to a database exactly with its different font and font styles. When I did research, I found code that does it as I showed. When I started to type in the code, I got to the line: TextRange tr = new TextRange(richTextBox.Document.ContentStart, richTextBox.Document.ContentEnd); I get as far as typing: TextRange tr = new TextRange(richTextBox. and then a list of available properties and methods drops down. Of that list, Document is not a part of. That is my proplem. I cannot access the Document property of my richTextBox. And as I said, I added the namespaces and the references I beleive are required. So how do I access that property?

Sorry to say, totally confusing question, you are saving rtf document to MS and in next code, you are not able to find rtf? Can you share the exact issue, you are facing?
