Is there a way to speed up the display of large amounts of text in the winforms text box?

Question

Is there a way to speed up the display of large amounts of text in the winforms text box? My application reads a file (which can be up to 20 MB in size) and then displays it in a text box (TextBoxX.Text = fileText;).

The process of displaying text is very slow, sometimes it takes several minutes. The problem is that this application is designed to display a large amount of text in a file, quickly for the user.

Is there any way to do this faster? Maybe some kind of caching is used?
