Typeof Problem

[squirrelly1]

I tried to use the following code:

Dim ctrl as Control
 
For Each ctrl in grpInfo.Controls
   If Typeof ctrl is TextBox Then
      'hrmf
   End If
Next

But When I get to the "hrmf" part, I don't have the ability to set/unset the Locked property of my Textbox control...

Any ideas on why?

Thanks,
