Font-Styles, ToolBox to use in C# for TextBoxes - Text

I'm searching a script or a toolbox in C#, where the User can change his own Textstyle, after or while writing in a TextBox..

Just like here I can change the style:

BOLD

Text

And change Colors, 开发者_如何学CTextSize and and and..

Hope u can show me a link or something similiar

As per my comment look at the RichTextBox

You might also want to look at this:

This is an open source control for text editing and you would be able to look at the code I think
