Is it possible to allow both authenticated and none authenticated users on a particular page, they can view content on that page but ones they click any button on that page the none authenticated user will be rediredted to logn page

here is the code i use buth it just redirecting none authenticated users ones they land on the page

if (HttpContext.Current.Session["userName"] == null)
        {
            Response.RedirectToRoute("HomePage");
        }
        else
        {
            if (!this.IsPostBack)
            {
                this.Populate();
            }
        }
    }


private void Populate()
    {

        string Populate = "GetUSERPost";
        using (SqlConnection con = new SqlConnection(constring4))
        {
            con.Open();
            using (SqlCommand cmd = new SqlCommand(Populate, con))
            {
                cmd.CommandType = CommandType.StoredProcedure;
               
                cmd.Parameters.AddWithValue("@Id", string.IsNullOrEmpty(Request.QueryString["Id"]) ? Page.RouteData.Values["Id"].ToString() : Request.QueryString["Id"].ToString());
             
                SqlDataAdapter sda = new SqlDataAdapter(cmd);
                DataTable dt = new DataTable();
                sda.Fill(dt);
                ViewState["DataTable"] = dt;
                GetAll.DataSource = dt;
                GetAll.DataBind();

yes, u can if u r using session then

where u want any one can access then write code without check of session. if u want that none authenticated user can't perform click button action then u can verify user on button click event.

like\

protected void button(object sender, EventArgs e)
    {
if (HttpContext.Current.Session["userName"] != null)
        {
perorm what ur button action u want to do
}
else{
Response.RedirectToRoute("HomePage");
}
}

if ur username session is not null then u can perform action, otherwise it will redirect u to homepage.

Hi micah,

What you need to do is you have to remove the Session checking code from page load event and call your Populate method only.

You need to write the session checking code on button click. On button click check if Session is not null then do the process else redirect the user to login page.

Ex:

protected void Page_Load(object sender, EventArgs e)
{
    if (!this.IsPostBack)
    {
        this.Populate();
    }
}

protected void Button1_Click(object sender, EventArgs e)
{
    if (HttpContext.Current.Session["userName"] == null)
    {
        Response.Redirect("Login.aspx");
    }
    else
    {
        // Do rest of code.
    }
}
