The ShowDialog routine will return a DialogResult enumerated value. For cancel it will be DialogResult.Cancel. If you have implemented this box yourself (C# doesn't support the standard 'input' box, you have to make one yourself) then on inside your cencel button click event you need to put:

Expand|Select|Wrap|Line Numbers
  1. this.DialogResult = DialogResult.Cancel;
  2. this.Close();
