jquery - How to add class in parent li using child link button from code behind in asp.net c#? -

here html code page :

<ul class="list quicker">     <li><asp:linkbutton runat="server" id="education_news" onclick="education_news_click" >education</asp:linkbutton></li>     <li><asp:linkbutton runat="server" id="immigration_news" onclick="immigration_news_click">immigration</asp:linkbutton></li>     <li><asp:linkbutton runat="server" id="visa_news" onclick="visa_news_click" >visa</asp:linkbutton></li> </ul> 

here code behind page i've used:

 protected void education_news_click(object sender, eventargs e)     {         string edu = education_news.text;         using (sqlconnection _con = new sqlconnection(_data.cs))         {             sqlcommand _cmd = new sqlcommand("select * tbl_brochures type=@type", _con);             _cmd.parameters.addwithvalue("@type", edu);             _con.open();             dl_brochures.datasource = _cmd.executereader();             dl_brochures.databind();          }      } 

i have when click on link button parent li of link button should change or add class li(this). have query got no solution.

you need add runat="server" li in aspx:

<ul class="list quicker">     <li runat="server"><asp:linkbutton runat="server" id="education_news" onclick="education_news_click" >education</asp:linkbutton></li>     <li runat="server"><asp:linkbutton runat="server" id="immigration_news" onclick="immigration_news_click">immigration</asp:linkbutton></li>     <li runat="server"><asp:linkbutton runat="server" id="visa_news" onclick="visa_news_click" >visa</asp:linkbutton></li> </ul> 

and add class in code-behind:

protected void education_news_click(object sender, eventargs e) {     ((htmlgenericcontrol) education_news.parent).attributes["class"] = "some-class"; }
