Clearing all radio buttons on a form

[shadowfyre]

Hopefully this is something quick.

I have a form with 4 group boxes. 2 of them have text boxes. I found how to clear them quick enough in past postings to this forum.

The basic idea is that you have to loop through the controls to find the group box then loop to find the text boxes, like this:

For Each c1 As Control In Me.Controls
            If TypeOf c1 Is GroupBox Then
                For Each c2 As Control In c1.Controls
                    If TypeOf c2 Is TextBox Then
                        c2.Text = Nothing
                    End If
                Next
            End If
        Next

So I tried to add another IF statement to uncheck the radio boxes. Something like:

If TypeOf c2 is RadioButton Then
    c2.Checked = False
End If

but that doesn't work. Checked is not a parameter that you can change for a control.

I only had 8 radio buttons, so I just did :

RadioButton1.Checked = False
        RadioButton2.Checked = False
        RadioButton3.Checked = False
        RadioButton4.Checked = False
        RadioButton5.Checked = False
        RadioButton6.Checked = False
        RadioButton7.Checked = False
        RadioButton8.Checked = False

But is there a better way?
