Very Computer

I am attempting to iterate through a collection of controls on a
TabPage.  As I iterate through them, I want to determine the type of
the control and then assign some property, i.e. radiobutton.checked =
False, TextBox.Text = "", etc.
I can get through both collections fine but once I determine the type,
do I have to cast the control to a radiobutton type to get it to
recognize the radio button properties?

fyi: TabEvents is a TabControl

Here's the code I have so far:

Dim MyTab as System.Windows.Forms.TabPage
Dim c as Control

For Each MyTab in TabEvents.TabPages
     For Each c in MyTab.Controls
        If c.GetType Is GetType(System.Windows.Forms.RadioButton) Then
           ????? How do I get my control to recognize the checked
                      property for a RadioButton  ????
        Then
     Next
Next

You have to cast c to the correct type. . .  e.g. CType(c, RadioButton)
