Hello
Can you please explain me how to change font and colour of selected text in RichTextBox? I was searching for long time and didn't find any solution. Only how to change font of entire TextBox and that's not what I want. If I could save the text to file with a new font it would be ideal :)
Thanks for any kind of help

Edit: I've done some experimenting

C#

FontDialog fd1 = new FontDialog();

 private void edit_Click(object sender, EventArgs e)
 {
     fd1.Font = textbox.SelectionFont;

     if(fd1.ShowDialog() != DialogResult.Cancel)
     {
       textbox.Font = fd1.Font;
     }
 }

but it looks like it saves it with the default font

You need to select some part of document using properties SelectionStart and SelectionLength. Then, use the properties like SelectionColor, SelectionBackColor and the like.

Ok, thanks to your and Dalek's answer I figured out how to change font of selected text. But when I want to save the file I don't know much how to do because it seems like ReadAll (when I want to see saved file) and WriteAll are just reading and saving the file in default font. Should I create FileStreams?

What, RichBox.SaveFile? Here:

Thanks, very useful codes are there :). But I still have the problem with saving font of text. What I'm trying to do is application which can save the text with changed font and when I load it again the font will appear as I changed it in application. I used the advices from great answers here and I can change the selected font in application but when I save it in txt for example and load it again using readalltext and the font in richtextbox is the last font I used in changing selected text :-/ Well, at least I can temporary change the font of selected text without saving

Hard to say, it could be some bug or something. If you save the RTF as a full document, you save it all, with all formatting/styles. Could be some logistics, whatever... you need to investigate it on simple samples. Look at the RTF manually, with word pad and plain-text editor, compare...

Good link but OP wants to save the text to a file, and you know that some characters might be in different colors.

LosEagle 21-Mar-12 18:10pm

Yes sorry that I wrote the important part of my question to end. Your answer was helpful but it saves in default font.

Sergey Alexandrovich Kryukov 21-Mar-12 18:38pm

Yes, sorry, but you did not read the answer to the end, that's the problem. OK, please first see my answer.

So, I voted 4 this time, as OP could use some clarification on where to look at, more exactly :-)
That's why I answered, too, to clarify...
