RichTextBox current line

[miket26]

Hi,

I am trying to get the text in a specific line in a Richtextbox. For example, I want change the font color for line 5 in a Richtextbox with 20 lines. I have a method to change the font color, but need to get the start and end position for that line. Anyone know a nice way to do this??

Thanks.

I would be tempted to use the GetLineFromCharIndex method inside a Binary Search, looking for the line# then subtracting 1 from the CharIndex until GetLineFromCharIndex returns the previous line.

Would you know a good way to scroll through the Richtextbox and look for \n, to determine the start and end position for the line? I've tried a few things, but none are working the right way. I'm also having trouble actually finding the carriage return.

Thanks.
