The analog of Controls in WPF

Question

I have several groupboxes with 3 radiobuttons in each one(they are all in the grid). In WinForms I could use Controls to access the controls by name and by index like:

groupbox1.Controls[0]

or

groupbox1.Controls["radiobutton1"]

So what I need to do in WPF is: I have a groupbox, and I need to access the certain radiobutton in it using index exactly like I would do in WinForms. Is it possible in WPF? Or how can I just reach the collection of the groupbox's children?

This question is not quite a duplicate of either of the commented questions.

Let's say you have the following setup

<GroupBox>
    <StackPanel x:Name="MyRadioButtons">
        <RadioButton x:Name="radio1">Radio1</RadioButton>
        <RadioButton x:Name="radio2">Radio2</RadioButton>
        <RadioButton x:Name="radio3">Radio3</RadioButton>
    </StackPanel>
</GroupBox>

You can access the child elements of an element by index or name, then cast to RadioButton:

(MyRadioButtons.Children[0] as RadioButton)             // By index
(MyRadioButtons.FindName("radio2") as RadioButton)      // By x:Name attr
