Demonstrates validators applied to the DateTextBox.

<script runat="server">

   protected void Page_Load(object sender, EventArgs e)
   {
     // the RangeValidator uses these two properties if assigned
      StartDate.MinDate = DateTime.Today.AddMonths(-1);
      StartDate.MaxDate = DateTime.Today.AddMonths(1);
      CompareToValueValidator1.ValueToCompareAsNative = DateTime.Today;
   }
   protected void Button1_Click(object sender, EventArgs e)
   {
      if (PeterBlum.DES.Globals.WebFormDirector.IsValid)
      {
         // save the data here
      }
