I have the following problem:
I have a list of UserControls for a wizard application and need to call a child method

```
List<UserControl> steps = new List<UserControl>();
steps.Add(new Step1());
steps.Add(new Step2());
steps.Add(new Step3());
steps.Add(new Step4());

```

All have StopTimeOut() method. How can I call: `steps[0].StopTimeOut();` ?

Thank you.
