RichTextBox question

[Ludwig]

Goal: text that is pasted in a RichTextBox control has to be formatted
(keywords should get another forecolor/style).

My first attempt to format the text was the traditional approach of
setting SelectionStart and SelectionLength, and then setting the
SelectionColor/SelectionFont.

This works fine for small updates, but when large amount of text is
pasted it takes seconds to format the whole text; sometimes it just
hangs. This is unacceptable.

Does anyone have any insight on how this can be done without the
performance problems?

Thanks!

You mean working with RTF directly? Do you happen to know a library
that can do such RTF-manipulations?

as Kevin Spencer said:
"Set the RichTextBox.SelectionColor property. Once set, the font color
will
be whatever you set it to. This applies to text that is appended to the

RichTextBox after setting the property. Otherwise, you can select text
already in the RichTextBox and set the SelectionColor to color that
text. "

So for example I set SelectionColor to red, and append some text, set
the SelectionColor to blue, append some other text, etc...

I tried it, but performance was still extremely poor

I am sorry. I haven't tried to optimize performance of RichTextBox
