Answer 1

I have read the answers in comments.

<a onClick="toggle(); return false;" />

For, href="" you cann add # like

<a href="#" onClick="toggle(); return false;">

Thanks

You are using asp:LinkButton which causes postback. Use html a instead to prevent it.

<a href="#" onClick="toggle();">

And if you want to show/hide your div use jQuery toggle.

<a href="#">

<script>
    $("a").click(function(){
      $("#showw").toggle();
    });
</script>
