Textbox will not update after editing

I have a page called info.aspx where a user inputs his/her information. After the information entered it goes to the next page called confirm.aspx where a user can confirm details or click on an edit button an it will take them back to the info.aspx where they can edit the information.

Once I click the Edit button it will prefill the values from the session variables. But the problem is that if I change the Last Name in the textbox and it goes to the next page it will not update, it keeps the old value. I debug and saw that tbLastName for example keeps the same Last Name even tho I change it. Am I missing something here?

I have this stored in Session Variables.

info.aspx.cs

protected void Page_Load(object sender, EventArgs e)
{
    if (Session["FirstName"] != null)
    {
        tbFirstName.Text = Session["FirstName"].ToString();
        tbLastName.Text = Session["LastName"].ToString();
        tbDOB.Text = Session["DOB"].ToString();
        tbEmail.Text = Session["Email"].ToString();
        tbTelephone.Text = Session["Telephone"].ToString();
    }
}
protected void btnNext_Click(object sender, EventArgs e)
{
    Session["FirstName"] = tbFirstName.Text;
    Session["LastName"] = tbLastName.Text;
    Session["DOB"] = tbDOB.Text;
    Session["Email"] = tbEmail.Text;
    Session["Telephone"] = tbTelephone.Text;
    Response.Redirect("~/appointments/confirm.aspx");
}

info.aspx

<table class="warning" style="width: inherit;">
<tr>
    <td>
        First Name:
    </td>
    <td>
        <asp:TextBox ID="tbFirstName" runat="server"></asp:TextBox>

When clicking on BtnNext, Page_Load event of info.aspx.cs is invoked before the Redirect. You just need to check !IsPostBack property in Page_Load of info.aspx.cs, just like jasonwarford mentioned. That way the textbox is not reset:

if (!IsPostBack)
{
    tbFirstName.Text = Session["FirstName"].ToString();
    tbLastName.Text = Session["LastName"].ToString();
    tbDOB.Text = Session["DOB"].ToString();
    tbEmail.Text = Session["Email"].ToString();
    tbTelephone.Text = Session["Telephone"].ToString();
}

It's rebinding the text boxes when you post back.

Try this:

protected void Page_Load(object sender, EventArgs e)
{
    if (Session["FirstName"] != null && !IsPostback)
    {
        tbFirstName.Text = Session["FirstName"].ToString();
        tbLastName.Text = Session["LastName"].ToString();
        tbDOB.Text = Session["DOB"].ToString();
        tbEmail.Text = Session["Email"].ToString();
        tbTelephone.Text = Session["Telephone"].ToString();
    }
}
