CompareValidator date with time

Question

I am using the following code to make sure my textbox has a valid date entered into it:

<asp:CompareValidator ID="cvStartDate" runat="server" Operator="DataTypeCheck" 
Type="Date" ControlToValidate="txtStartDate" ErrorMessage="Please enter the 
start date in the format of dd/MM/yyyy hh:mm"/>

But when I enter a date with a time validation fails. Is there a way to get this type of validator to accept dates with times too or do I have to build a custom validator for this? If I have to go down the custom validation route what would you suggest?

What is the value you are entering ? do you get any exceptions ? — V4Vendetta, Jan 30 '13 at 12:45
I entered `30/01/2013 10:00`, no exception but it just showed the error message saying it wasn't a valid date. If I took the 10:00 off it validated ok — Pete, Jan 30 '13 at 12:49
`CompareValidator` does not have a `DateTime` type. You'll have to use a `CustomValidator` or a `RegularExpressionValidator`. — juharr, Jan 30 '13 at 12:57
After much googling I have come to the same conclusion, but I think I have a work around with the use of the date comparer and a couple of dropdownlists for hour and time — Pete, Jan 30 '13 at 13:00
@Pete - Your first line says "...to make sure my textbox has a valid date entered into it" and you say later that "when I enter a date with a time validation fails". I was unable to understand if the case where user enters a date and time is a valid scenario for your application. — shree.pat18, Nov 06 '13 at 10:26
ah yes - they needed to enter a valid date that also had a time too - with the following format: `dd/MM/yyyy hh:mm` — Pete, Nov 06 '13 at 10:27

@Prabu is correct though. Use CustomValidator.

CompareValidator only works with dates and not date & time.

protected void CustomValidator_Date(object source, ServerValidateEventArgs args)
    {
        IFormatProvider culture = new CultureInfo("en-AU", true);
        try
        {
            String[] formats = { "dd MM yyyy", "dd/MM/yyyy", "dd-MM-yyyy" };
            DateTime dt1;
            dt1 = DateTime.ParseExact(args.Value, formats, culture, DateTimeStyles.AdjustToUniversal);
            args.IsValid = true;
        }
        catch
        {
            args.IsValid = false;
        }
    }

Its better to use custom validator to validate dates.. To avoid user to enter date and time,

use Ajax calender extender and set readonly property true.

The CalendarExtender does not have that option ReadOnly="true" – Fandango68 Feb 18 '16 at 00:13
