Another VS 2005 Question

[Gunawan]

Dear All,
I would like to know how to prevent row one from display (toggle) on a
Button btnOne on the form.
If I click the btnOne on the postback response row one of the table will not
displayed.

<table>
<tr><td>One</td><td>AAAAA</td></tr>
<tr><td>Two</td><td>BBBBB</td></tr>
</table>

Thank you.
Regards,
Gun
