How to loop through all controls in a Windows Forms form or how to find if a particular control is a container control?

Question

I will tell my requirement. I need to have a keydown event for each control in the Windows Forms form. It\'s better to do so rather than manually doing it for all c

Answer 1

A simple recursive function should do it.

private void AddEvent(Control parentCtrl)
{
  foreach (Control c in parentCtrl.Controls)
  {
    c.KeyDown += new KeyEventHandler(c_KeyDown);
    AddEvent(c);
  }
}
