What is the preferred way to find focused control in WinForms app?

by

If you have other calls to the Windows API already, there’s no harm in using Peters solution. But I understand your worries about it and would tend to a similar solution as yours, using only the Framework functionalities. After all, the performance difference (if there is one) shouldn’t be significant.

I would take a non recursive approach:

public static Control FindFocusedControl(Control control)
{
    var container = control as IContainerControl;
    while (container != null)
    {
        control = container.ActiveControl;
        container = control as IContainerControl;
    }
    return control;
}
