Non-javascript way . . aspx page:

Code Behind:

Protected Sub CustomValidator1_ServerValidate(ByVal source As Object, ByVal args As System.Web.UI.WebControls.ServerValidateEventArgs) Handles CustomValidator1.ServerValidate
    If Not CheckBox1.Checked Then
        args.IsValid = False
    End If
End Sub

For any actions you might need (business Rules):

If Page.IsValid Then
   'do logic
End If
