WPF RichTextBox appending coloured text

Question

I\'m using the RichTextBox.AppendText function to add a string to my RichTextBox. I\'d like to set this with a particular colour. How can I do this?

Answer 1

Just try this:

TextRange tr = new TextRange(rtb.Document.ContentEnd,­ rtb.Document.ContentEnd);
tr.Text = "textToColorize";
tr.ApplyPropertyValue(TextElement.­ForegroundProperty, Brushes.Red);
