How to change the color of some text in textbox - Silverlight 3?

Question

Hello, I have a usual TextBox. I know in order to change the color of some text I can use Run tag. But when I try to use it imperatively instead declaratively (because I need to do that dynamically) I have the text in TextBox like

AAA<Run...>Text to be changed in color</Run>

and sure nothing in color changes. How can I change the color of some text in some program way? Thanks

Answer 1

I'm fairly sure you have to use a RichTextBox for that, TextBox only works with plaintext.
