Question

I have 3 classes:

class A 
{
    public B b = new B();    
    public bool flag {get; set;}
}

class B
{
   piblic C c = new C();
}


class C
{
   public void foo()
    {
  //iterates a dataTable with column "someBoolCondition"
  // I want to set A's bool to true, after the first record that has 'true' in column
  //"someBoolCondition". Thus is thought to avoid bool memebers in each class.
    }
}

What it the best way set A’s flag to ‘true’ from C’s foo?

TIA

Your C can fire an event every time C changes its own bool. Your A can subscribe to event and update itself. You can also pass an abstracted interface of A to b and C for letting them push the change directly.
