2.0: setting TextBox.Text from another page

[R.A.M.]

Hi,
I need to set BirtDate TextBox with a date taken from another browser
window with Calendar control. I tried this way:
On first page I have:

Birth date: <asp:TextBox ID="BirthDate" runat="server"
ValidationGroup="BirthDate" />

with behind-code:

protected void Page_Load(object sender, EventArgs e)
{
...
Session["BirthDate"] = BirthDate;
}

On second page I have Calendar control and behind-code:

protected void Kalendarz_SelectionChanged(object sender, EventArgs e)
{
((TextBox) Session["BirthDate"]).Text =
Calendar.SelectedDate.ToString().Substring(0, 10);
}

Although this assigments works there's no visible result on first
page. Could you explain me please why? How to write correct code?
Thank you very much.
/RAM/

// Populate the Session variable
Session["BirthDate"] = Calendar.SelectedDate.ToString().Substring(0, 10);

// Cast the Session to a String object to access the value of the variable
String birthDate = (String)Session["BirthDate"];
