I am writing a MDI application, I need to add a text editor form to it which can do something like what NotePad does! I wonder if there is already such a Form that I can simply add to my MDI form (I know I sound lazy!)
Or I have to do it all myself 🙁 !!!
as others told you from your description it looks like a multiline textbox would do the trick, sometimes such control is called TextArea and allows you to show vertical and horizontal scrollbars as needed.
if you use a RichTextBox then you can have RTF text in it, so bold, italic, underlined and other formatting options that are actually not supported in NotePad, NotePad++, TextPad etc.
if you decide to stick on pure TEXT format and not RTF one of the best control to handle this is available here for free: Scintilla.NET
the features and possibilities with this great control are endless, like code formatting, collapsable regions and much, much more.
