Question

I need save login of my Login page in cookie for show every time when page is loaded

I have create for save login in cookie, in Button click event. but, because in the Post Back, Page_Load before button, so when page_load put cookie information in the TextBox, my cookie is empty

What can I do for resolve this?

protected void Page_Load(object sender, EventArgs e)
{
    // This time, Cookies["login"].Value is empty
    tbLogin.Text = Response.Cookies["login"].Value;
}

protected void Button1_Click1(object sender, EventArgs e)
{
    Response.Cookies.Add(new HttpCookie("login", tbLogin.Text));
}

Answer 1

Try using Page.IsPostBack property.

protected void Page_Load(object sender, EventArgs e)
{
    if(!Page.IsPostBack)
    {
        tbLogin.Text = Response.Cookies["login"].Value;
    }
}

protected void Button1_Click1(object sender, EventArgs e)
{
    Response.Cookies.Add(new HttpCookie("login", tbLogin.Text));
}
