convert checkbox code to link in asp.net and c#

hi,

I want to convert checkbox into link. Clicking on checkbox will expand/collapse table. How the below can be converted if the checkbox is a link.

<asp:CheckBox id=chkExpandView runat="server" Font-Names="Arial" Font-Size="X-Small" AutoPostBack=true  OnCheckedChanged="chkExpandView_CheckedChanged" />
                    <font size="2" face="Arial"> <b>Expand All</b></font>

C#
 protected string DisplayScriptExpandCollapse()
    {
        if (this.chkExpandView.))
            return "display:block;";
        else
            return "display:none;";
            }
