Problem with CompareValidator control

[Andres Aguiar]

Hi,

I'm using the CompareValidator with a DateTime field using the dd/MMM/yyyy
format (example "07/Jun/2004" ) .

The compare validator seems not work with this format. It always says that
the date is invalid.

I'm using the CompateValidator with Operator= "DataTypeCheck" and
Type="Date".

<asp:CompareValidator runat="server" id="ValidateDate"
ControlToValidate="InvoiceDate" Operator="DataTypeCheck" Type="Date"
ErrorMessage="invalid date" ></asp:CompareValidator>

What am I missing?

Thanks

Andres

Hi Andres,

As for the Validation Date problem on using the CompareValidator control.
This is because the CompareValidator's support on date validtion only
contain some basic date formats such as:
mm/dd/yyyy or dd/mm/yyyy ... and not all those formats we can cover.
Also, we can't force it to validate regarding on a specified format.
And as for your scenario, I think the CustomValidator or RegularExpression
Validator control maybe suitable. And here is a former thread discussing on
the similiar problem, you may have a look:

Also, below are some regex for validting date/time resources which maybe
useful if you'll use the RegularExpressionValidator to check the date input:
