How to set text in wpf richtext box

Hi,

Unlike other controls in wpf, richtextbox doesn't have content as property for setting content. Richtextbox has Document property to set or get the content or text.

Use below code

// Create a Flow Document

FlowDocument ObjFdoc = new FlowDocument();

//Add paragraphs to flowdocument Blocks property

Paragraph ObjPara1 = new Paragraph();

ObjPara1.Inlines.Add(new Run(" First Paragraph "));

Paragraph ObjPara2 = new Paragraph();

ObjPara2.Inlines.Add(new Run("Second Paragraph"));

ObjFdoc.Blocks.Add(ObjPara1);

ObjFdoc.Blocks.Add(ObjPara2);

// Finally Assign the FlowDocuemnt object to Document Property fo RichTextBox Control.

richTextBox1.Document=ObjFdoc;
