Question

I am a new to ASP.Net. Please, explain me what I need to add.
I clicked this page before login to take user to login page by “FormsAuthentication.RedirectToLoginPage();”. But After Page_Load , it goes to “dsRequestList_Selecting”. I assumed it goes directly to Login page, but here some reason it goes to login page after dsRequestList_Selecting(). What do I need to do?

protected void Page_Load(object sender, EventArgs e)
    {
        if (IsPostBack)
        {
            if (!HttpContext.Current.User.Identity.IsAuthenticated)
            {
                FormsAuthentication.RedirectToLoginPage();
            }

        }
        else
        {
            if (!HttpContext.Current.User.Identity.IsAuthenticated)
            {
                FormsAuthentication.RedirectToLoginPage();
            }
        }
    }

protected void dsRequestList_Selecting(object sender, LinqDataSourceSelectEventArgs e)
    {
       //Selecting
    }

Don’t go this way.

Use Web.config (or, for MVC, the [Authorize] attribute) to secure pages. You don’t need this kind of code and you don’t want the susceptibility to errors (in every page) that it brings.

You only need

<configuration>
    <system.web>
       <authorization>
         <deny users="?" /> 
       </authorization>

       ...
    </system.web>

    ....
</configuration>

to secure all your pages in the same folder as this web.config. The loginform is automatically excepted.
