I've tried using RichTextBox but when the text in it becomes large, it becomes noticeably slow to update the text.

it's very fast in displaying 100MB++ of text data complete with highlights and formatting. And I believe it's not richtextbox.

Eddy Vluggen wrote:

It's not the control that makes it fast, it's the way they handle loading. Doing formatting and highlighting on 100Mb+ costs time, but you don't have to highlight what you cannot see. I'd also imagine that such applications load the parts that they're actually working with, as opposed to loading the entire file into memory.

Still, the ListBox would be the way to go.

Richtextbox doesn't handle it the same way?

Ajakblackgoat wrote:

But still it lacks textbox-like select & copy functionality.

I know what it's limitation which hinders me from using it for this particular app.

Perhaps I didn't post my question clearly. I was asking if anyone had come across a control which does the same, not how to do it.
