I would use one button that defaults to "Hide".
<input type="submit" value="Hide" name="btnStatus" />
When it's clicked, the form submits and your ASP code checks the value - if the value equals Hide then have the ASP run some SQL to update the table to status 0 (and then write out the button with a "Show" value), else update the table status to 1 (and then write out the button with a "Hide" value again).
