How to call Session.Abandon()

Question

User-259260637 posted

I have an ASP:Hyperlink that i am using to login users to an admin area. When they login I am changing the text of the Hyperlink.

 if ((Session["userLogin"] == null) && (Convert.ToBoolean(Session["userLogin"]) != true))
        {
            lnk_admin.Text = "Admin";
            lnk_admin.NavigateUrl = "/admin/login.aspx";
        }
        else
        {
            lnk_admin.Text = "Logout";
            lnk_admin.NavigateUrl = "/";

            //Session.Abandon();
            //Response.Redirect(Request.RawUrl);
        }

 I wondered how could I call Session.Abandon() when the user clicks the Hyperlink when the text is Logout

I have managed to do this by checking the url:

 else
        {
            lnk_admin.Text = "Logout";
            lnk_admin.NavigateUrl = "/";
            var path = HttpContext.Current.Request.Url.AbsolutePath;
            if (lnk_admin.Text == "Logout" && path != "/admin/edit-member.aspx")
            {
                Session.Abandon();
                Response.Redirect(Request.RawUrl);
            }
        }

Use LinkButton for the same and on click of LinkButton check the text and based on it make decision.

protected void lnk_admin_Click(object sender, EventArgs e)
        {
            if(lnk_admin.Text =="Logout")
            {
                Session.Abandon();
                Response.Redirect(Request.RawUrl);
            }
        }

I'm wonder why you are try with hyper link button. You have a control called "Link button" which is also displayed as a hyper link. Also it have a "onclick" event. In that you could call the Session.abondon() code. Hope this helps!

Hi StudentRik,

There is no onClick event on the Hyperlink control

A HyperLink has no postback event when clicked .If you want to execute server code upon a click in a link, then you could use the ASP.NET control <asp:LinkButton> ,this is just like a button and will allow you to hook up Server Side Events and at the end you can just redirect the viewer to any page.

That's the reason i ask to use LinkButton instead of Hyperlink.

Hi,

Use link button:

<asp:LinkButton id="myLink" Text="Hi" OnClick="LinkButton_Click" runat="server"/>

and 

void LinkButton_Click(Object sender, EventArgs e) 
{
   // your code here
}
