The information may not be current if it is altered after the webpage has loaded.
Consider exploring page methods (an ajax system) or another method involving ajax for real-time updates.
When inline code is displayed on a page, it remains static and does not change, which is the expected behavior. It is recommended to use a Hidden field instead.
Here is an example of how to mark-up:
<asp:HiddenField ID="HiddenField1" runat="server" />
<asp:Button ID="Button1" runat="server" Text="Button" onclick="Button1_Click" />
And the corresponding code-behind implementation:
protected void Button1_Click(object sender, EventArgs e)
{
Session["file"] = "Data Here";
HiddenField1.Value = Session["file"].ToString();
}
Additionally, here is a snippet of JavaScript that retrieves the value from the HiddenField:
alert(document.getElementById('<%= HiddenField1.ClientID %>').value);
