How to redirect to another page after a delay

Question

I have a sign-in box in my webpage which is inside an UpdatePanel

Answer 1

You can write a block of Javascript with a delay and redirect to the page with this code

public void btnSignIn_Click(object sender, EventArgs e)
{
    lblSSuccess.Text = "We found you, now redirecting...";
    lblSSuccess.ForeColor = ColorTranslator.FromHtml("#037203");
    Session["UseIsAuthenticated"] = "true";

    ScriptManager.RegisterClientScriptBlock(this, typeof(Page), "redirectJS",
    "setTimeout(function() { window.location.replace('homepage.aspx') }, 5000);", true);
}
