So how much are you paying for someone to write this code for you? How are you going to be paying them?

Hi,

I am not going to write this code but ofcourse i will guide you how can you do that.

You can use Compare/Custom Validation Control for that. This[^] example show you how can you call a server side function. Even you can write javascript to validate your date.

Hope you can do it. As i have already given an example in the link
Thanks

5'ed :) You can use RegularExpressionValidator for date input too, plus the controls explain by @amitgajjar =)

Use Copmare Validator for validation in following way its solved your problem.....

XML

<asp:TextBox runat="server" ID="MyTextBoxFromDate"></asp:TextBox>

<asp:TextBox runat="server" ID="MyTextBoxToDate"></asp:TextBox>

 <asp:CompareValidator  ID="CompareValidator1" runat="server" ErrorMessage="Date range not       valid." ControlToCompare="MyTextBoxFromDate" ControlToValidate="MyTextBoxToDate"             ValueToCompare="MyTextBoxFromDate" Operator="GreaterThanEqual" Type="Date"          ValidationGroup="NameofGroup"></asp:CompareValidator>
