give same property to all textbox controls

Question

how to give same property to all textboxes present in the same form.

      foreach (var textbox in this.Controls.OfType())
        {
            t

How about an extension method to do it, called from your tabcontrol container...

public static class ControlExtensions
{
    public static void SetContextMenuOnChildTextBoxes(this Control control)
    {
        if (control is TextBox)
        {
            control.ContextMenu = new ContextMenu();
        }
        if (control.Controls != null)
        {
            foreach (Control controlChild in control.Controls)
            {
                controlChild.SetContextMenuOnChildTextBoxes();
            }
        }
    }
}

This could be put in a common area of code so that it could be called from any parents that wanted this functionality.
