If your section ID is REQUEST, the ID of the panel containing the section’s title is REQUEST_TITLE. You can modify the title dynamically using code-behind:
protected void Page_Load(object sender, EventArgs e)
{
base.Page_Load(sender, e);
Label title = (Label)REQUEST_TITLE.Controls[0];
title.Text += " " + DateTime.Today.ToString("dd/MM/yyyy");
}
