Question

I am using a function for logout of client in asp.net C# previously i was using asp.net button’s click event for calling it but now i want to call it from one of navigation menu item.

Answer 1

The simplest way to do this is to set a page that when requested logs the user out then redirects them to the login screen, that way you can create a simple static <a href="#"> to the page and it’ll work regardless of where you put it.

You can actually reuse your existing Login page logic, but make the logout action be done by querystring. Like so:

<a runat="server" href="~\Path\To\Login.aspx?logout=1">Logout</a>

In your LoginPage class:

public override void OnLoad(Object sender, EventArgs e) {

    if( Request.QueryString["logout"] == "1" ) {

        FormsAuthentication.SignOut();
        Response.Redirect("~\Path\To\Login.aspx");
    } else {
        if( Page.IsPostBack && (Page.Validate(), Page.IsValid ) ) {
             // your current login logic
        }
    }
}

HTH.
