Demonstrates validators applied to the TimeOfDayTextBox.

<script runat="server">

   protected void Page_Load(object sender, EventArgs e)
   {
     // the RangeValidator uses these two properties if assigned
      StartTimeOfDay.MinTime = new TimeSpan(10, 0, 0);
      StartTimeOfDay.MaxTime = new TimeSpan(16, 0, 0);
      CompareToValueValidator1.ValueToCompareAsNative = new TimeSpan(10, 0, 0);
      DifferenceValidator1.DataBind();
   }
   protected void Button1_Click(object sender, EventArgs e)
   {
      if (PeterBlum.DES.Globals.WebFormDirector.IsValid)
      {
         // save the data here
      }
   }

<p>These two TimeOfDayTextBoxes are associated with numerous validators.</p>
<p><i>These examples use the TimeOfDayTextBox but also work with DurationTextBox.</i></p>
Start Time:
<des:TimeOfDayTextBox ID="StartTimeOfDay" runat="server">
   <PopupTimePicker Activate="true" AutoFillStartTime="9:0:0" AutoFillEndTime="18:0:0" AutoFillIncrement="60" />
</des:TimeOfDayTextBox><br/>
End Time:
<des:TimeOfDayTextBox ID="EndTimeOfDay" runat="server">
</des:TimeOfDayTextBox><br/>
<br/>
<des:Button ID="Button1" runat="server" Text="Validation and Submit" OnClick="Button1_Click" />
<br/>

<h2>DataTypeCheckValidator</h2>
<a href="../../Validation/Validators/Controls/DataTypeCheckValidator.aspx" class="ControlClass">DataTypeCheckValidator</a> on both textboxes (always add these validators. Do not assume client-side formatting features
of the TimeOfDayTextBox will protect you)<br/><br/>
<des:DataTypeCheckValidator ID="DataTypeCheckValidator1" runat="server" ControlIDToEvaluate="StartTimeOfDay"
   ErrorMessage="Invalid entry in Start Time" 
   NoErrorFormatter-Mode="FirstTime" NoErrorFormatter-Text="Validation not invoked yet on Start Time">

<h2>CompareTwoFieldsValidator</h2>
   <a href="../../Validation/Validators/Controls/CompareTwoFieldsValidator.aspx" class="ControlClass">CompareTwoFieldsValidator</a> where Start Time is less than End Time<br/><br/>

<h2>DifferenceValidator</h2>
<a href="../../Validation/Validators/Controls/DifferenceValidator.aspx" class="ControlClass">DifferenceValidator</a> where the two times must be more than 5 hours apart.
