RichTextBox questions?
-
1. How do I determine on which row/line/ is the cursor? 2. How can I set a background color of a line?

GetCharIndexFromPositionwill accept some coordinates and return the index of the character under that point.GetLineFromCharIndexwill get the line from the character index. (Try consulting the help documentation or even just looking through the intellisense, the method names are quite simple :rolleyes:)Cristoff wrote:

Unless you override the painting of the control there is no built-in way to do this. Take a look at some of the articles regarding the
RichTextBoxhere on CP for ideas on how to do this. (There is one I remember that draws the line numbers, should be quite simple to re-write this to background fill the lines).

Try: Numbered TextBox CP search didn't work so this was found through Google, limiting the search to www.codeproject.com. [edit]While I was looking for the article it looks like you found it, hopefully it's the same one[/edit]

Thank you! I haven't used codeproject site for quite some time and I haven't searched correctly.

I know too I always have to suppress my hooliganish instincts and try to behave civilized.
