Compare Validator Control Error

[lsmyth1717]

Can someone help me. I'm trying to use the following validator control and compare a date to a date defined in the code-behind page. My code is below along with my error message I get when the page is rendering in the browser. Has anyone any idea what I've done wrong?

<asp:CompareValidator ID=cvDate Font-Size=small ForeColor=red Runat=server ErrorMessage="Please work"
Operator=LessThanEqual Type=Date ControlToValidate=txtStartDate ValueToCompare="<%#CompareDate()%>">*</asp:CompareValidator>

/// <summary>
/// Return a date for comparison
/// </summary>
/// <returns>a date string</returns>
public string CompareDate()
{
return DateTime.Today.ToShortDateString();
}

Browser Error Message
The value '' of the ValueToCompare property of 'cvDate' cannot be converted to type 'Date'.

The value '' of the ValueToCompare property of 'cvDate' cannot be converted to type 'Date'.

That means that it can't convert '' to a date as it isn't a valid date (i.e. it is null).

Ok, but i've used this before and got this working fine so still can't understand it. My function that returns the date seems fine to me and should return a valid date and has done in the past. Any ideas what i've done wrong?

Well the error suggests that it isn't returning a valid date so you will have to check that it is
