Question

I want to know that how to use session in asp.net for that I use the following code:

protected void Page_Load(object sender, EventArgs e)
{
    string academics = "academics";
    Session["header_value"] = academics;
}

then I want to use that value in following code

<a href="academics.aspx">
     <%if("header_value"=="academics")
     {%>
          <div id="academics" class="pri-nav active"></div>
     <%}else{%>
          <div id="academics" class="pri-nav"></div>
     <%}%></a>

I also want to know that is there any other way to pass value to .cs other than session?

Answer 1

Protected or public variables can be accessed on the page.

protected string ActiveNav = "";
protected void Page_Load(object sender, EventArgs e)
{
    ActiveNav = "academics";
}

and

   <a href="academics.aspx">
       <div id="academics" class="pri-nav <%= ActiveNav=="academics"? "active" :"" %> "></div>
   </a>
