Question

I have a richtextbox in an app and I’d like key words to be in another color, how can I do this?

Thanks

Answer 1

you can use:

richTextBox1.SelectionColor = Color.Yellow;
richTextBox1.SelectionBackColor = Color.Blue;

to select a text set:

richTextBox1.SelectionStart = text_position_in_editor (caret position)

richTextBox1.SelectionLength = text_length

then set SelectionColor … (see all properties starting with Selection…)

Or, you can set directly the Rtf property (or richTextBox1.SelectedRtf) which contains formatting info.

Type some text in WordPad, change it’s formatting, copy and paste it into your RichTextBox, show the property Rtf value, you should be able to learn faster how to meet your needs.
