Question

I wonder if there is a way to directly control some events when a boolean field is changing from true to false?

something like using delegate?

Actually I have lots of user input controls (check box, text box and etc..) and I am looking for a way around the using of foreach and control.disabled stuff.

Properties are always good to fire up event from within:

private bool check = false;
public bool MyCheckboxChecked
{
    get
    {
        return check;
    }

    set
    {
        if (check == true && value == false)
            MyEvent("MyCheckboxChecked is about to change from true to false!");
        check = value;
    }
}

If you want to monitor public fields of controls (ie CheckBox.Checked), you can always hookup for events already provided by them like CheckedChanged.
