Enable webforms when checkbox is checked

hey guys I'm new with visual studio and have been searching for this solution.

I want to create a form that when the checkbox is checked the radio buttons following it will become enabled.

This is what I have so far.  It works, however it's not dynamic.  I have to click the submit button before both RadioButton10 and RadioButton11  enabled. Protected Sub CheckBox1_CheckedChanged(ByVal sender As Object, ByVal e As System.EventArgs) Handles CheckBox1.CheckedChanged

RadioButton10.Enabled = True

RadioButton11.Enabled = True

End SubThanks!
