RichTextBox (WPF) does not have string property "Text"

c#, richtextbox, wpf, wpf-controls

Solution

to set RichTextBox text:

richTextBox1.Document.Blocks.Clear();
richTextBox1.Document.Blocks.Add(new Paragraph(new Run("Text")));

to get RichTextBox text:

string richText = new TextRange(richTextBox1.Document.ContentStart, richTextBox1.Document.ContentEnd).Text;

Problem

I am trying to set/get the text of my RichTextBox, but Text is not among list of its properties when I want to get test.Text... I am using code behind in C# (.net framework 3.5 SP1) ``` RichTextBox test = new RichTextBox(); ``` cannot have `test.Text(?)` Do you know how come it can be possible ?
