Check Session variable and Redirect to login page before page load

Question

How can I check a variable and redirect to another page before the page loads using ASP.NET?

I\'m aware of the life cycle, and PageInit() sounds like it

Answer 1

you can place this code anywhere in the masterpage to check a variable and redirect to another page before the content page loads.

protected override void OnInit(EventArgs e)
    {
        base.OnInit(e);

        if (string.IsNullOrEmpty(Convert.ToString(Session["email"])) ||string.IsNullOrEmpty(Convert.ToString(Session["mobile"])))
        {
            Response.Redirect("Login.aspx");
        }
    }
