This question already has an answer here: Color different parts of a RichTextBox string 8 answers I have a RichTextBox that I write a string to every time I click a Form button. Each string begins with the string "Long" or "Short" and ends with a newline. Each time I add a string, it appends to the bottom of the RichTextBox. I'd like to color each line red if it beings with "Long" and blue if it begins with "Short". How can I do this? Sure, so what you can do is use the SelectionStart, SelectionLength and SelectionColor properties to accomplish this. It works quite well. Check out this page

How can I make a hyperlink work in a RichTextBox?

When I add www.stackoverflow.com into my RichTextBox and run the program it is shown in blue and as a hyperlink yet when I click it nothing happens. How can I fix this? Make sure the text property includes a valid url. E.g. http://www.stackoverflow.com/ set the DetectUrls property to true Write an event handler for the LinkClicked event.

If you just pass the url to process start (as per below) then Windows will

The only issue with using Rich Text Box as highlighter is slow performance on coloring, in cases when the size of the document is big. For a medium size documents this issue can be fixed by delayed highlighting. As

问题 How can I use RichTextBox Target in WPF application? I don't want to have a separate window with log, I want all log messages to be outputted in richTextBox located in WPF dialog.
