Define what you mean by "divide the textgbox text in two parts"... What exactly is supposed to happen?

Horizontally or vertically. Diagonally would be difficult.

If you want to break the text into two parts on entry of + character then I think the KeyPress event of TextBox can be handled to replace the + character with \n as shown below:

TextBox textBox1 = new TextBox();
textBox1.Multiline=true;
textBox1.Height=100;
textBox1.KeyPress += (s, args) => {
if (args.KeyChar=='+')
args.KeyChar= '\n';
};
Controls.Add(textBox1);

If you want to retain + and then break the text into next line then replace args.KeyChar = '\n'; with SendKeys.Send("{ENTER}"); To run the above code, create a Windows Forms application in C#, place the above code in the Form.Load event handler and run the application.

Hide this text box and show two new ones on pressing the + button.
