I am creating a custom textbox control, that inherits a standard textbox contro, and I would like to leave some space on the right sied of textbox, so I can use it for some information purpose. Ex

TextBOx.Width=100
I would like letters to be shown in 80 pixels only (and after if more letters are typed, they are scrolled, just like in original textbox behaviour, and the last 20 pixels should be reserved. HOw to change this "letter" rectangle?

Any ideas?

you can use maskedtaexbox containter to formulate the text in the textbox

I have another meathed.you can lay a splitcontainer in a textbox,an then lay a second textbox in the splitcontainer,and make  the boderstyle=none and the multiline=true. that will done.hehe

I hope this will help you although there  maybe some better sollutions.
