Nelson,

You *can* handle a KeyPress event in a sub-class of a TextBox:

// In the sub-class's Contstructor:
this.KeyPress += new KeyPressEventHandler(this.KeyPressHandler);

// and then the Handler:
protected virtual void KeyPressHandler(object sender, System.Windows.Forms.KeyEventArgs e)
{
  if (e.KeyCode == Keys.PageDown)
  {
    // or whatever it is you're checking for, handle it here and then include this:
    e.Handled = true;
  }
}

For KeyPresses that you don't handle, e.Handled will not be true and C# will process the KeyPress as normal.

>>> Through "base" keyword in C# you can call base implementation of the overriden method (as this does DODEFAULT() in VFP). If you do not use "base.method_name" in your method called "method_name", this is equivalent to use NODEFAULT() in VFP.
