Scrolling all but the top line in a multiline textbox

I have a multiline textbox in a WinForms application. What I'd like to do is always have the top line visible, even if it scrolls. Is there some trick someone knows to do this?

The simple answer; depending on the appearance you are going for is to use existing windows controls to get the effect you want.

You can use a label control above a textbox and allow the textbox to scroll. You can use two textbox - the top with it's .multiline property set to false, while the bottom allows scrolling.

You could encapsulate this all into a user control for reuseability.

Beyond that, I think you'd be looking at a fairly large project to implement your control (or at least overriding the onPaint() event of the textbox) with the desired behavior.

Fake it. Use two TextBox objects, draw your own borders. You will need to deal with wrapping to the next line yourself.

You could also copy the first X characters to a label so when the TextBox scrolls they can see the first line in the label.

Unless it is an essential feature I would try to cut it.
