Regular Expression validator problem

[Jmshastri]

Hi all. How can i validate a date in format of DD/MM/YYYY using regularexpressionvalidator control? please help me out.

Use this pattern: "\d{2}/\d{2}/\d{4}". This will of course only verify that the format is correct, it can't verify that the date actually exists. You can make the verification a bit better by making sure that the date is in the range 1 to 31 and so on, but still that won't see that a date like 31/02/2006 does not exist. --- b { font-weight: normal; }

You can use the CompareValidator with the DataTypeCheck operator and Type="Date" to validate if the textbox value is a valid date. You also should remember that the date format used by the validator is specified based on the current culture value when the validator control renders, for example if the current culture is set for the "en-GB" value, then the dateorder will be mdy, and the validator will accept the values like 18/4/2006 or 18/04/2006 ..., the delimiter can be either - or /. If you want to use the fixed format like you said, you can either implement a custom validator for this or use an additional RegularExpressionValidator with the pattern suggested by Guffa. For more information on how to set the culture value, you can see MSDN[^]

Use Compare Validator that would be correct solution in this scenario "Aim to go where U have never been B4 and Strive to achieve it" http://groups.yahoo.com/subscribe/dotnetforfreshers http://himabinduvejella.blogspot.com
