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);
}

Answer 2

first create a function that makes the action you need (redirect to page for example)

Second add timer to your markup and set the time interval to 5000 ( 5 sec) and mark the timer as enabled=false so the timer wont start after the page loading

once the user is validated successfully, show the message you want then enable the timer

Answer 3

There are many ways to do this but I love to use this code because it works well when used in many different circumstances. This is with a 5 second delay.

HtmlMeta oScript = new HtmlMeta();
oScript.Attributes.Add("http-equiv", "REFRESH");
oScript.Attributes.Add("content", "5; url='http://www.myurl.com/'");
Page.Header.Controls.Add(oScript);
