Hi

Try this code i given below.

//Declare a text box which is hidden in aspx page.

 

 <div style="display: none;">

<asp:TextBox ID="hdnTodaysDate" runat="server" Text="11/10/2011"></asp:TextBox>

</div>

In your page load, use this code in code behind.

// Here i am assigning current system date to the text box.

 hdnTodaysDate .Text  = DateTime.Now.ToString("MM/dd/yyyy");

Use the CompareValidator to compare your date with the given date.

use the below code in aspx page. 

 

 <asp:CompareValidator ID="CompareValidatorBookingDeadline" runat="server" ControlToCompare="hdnTodaysDate" ControlToValidate="txtDOB"  ErrorMessage="Please enter valid date."                                             Operator="LessThan" ValidationGroup="vgUserRegistration" Type="Date"></asp:CompareValidator>

 

Happy coding.
