Delete cookies while using master page using C# in ASP.Net

Hi Prasunjeet,

As you are using master page the cookie is not removed. So you need to reload the page inorder to delete / remove the cookie. Refer the below code.

C#

protected void DeleteCookie(object sender, EventArgs e)
{
    HttpCookie cookie = Request.Cookies["PdGuestID"];
    if (cookie != null)
    {
        cookie.Expires = DateTime.Now.AddDays(-1);
        Response.Cookies.Add(cookie);
        Response.Redirect(Request.Url.AbsoluteUri);
    }
}
