Hi people I have the following express validation
[Required]
[RegularExpression("{0:d/M/yyyy HH:mm:ss}" ,
ErrorMessage = "Wrong Syntax")]
public string Posted { get; set; }`
But it does not allow the following input which am showing as a example of date and time:
12/12/2011 00:00:00 (I do not want these exact numbers the date and time should allow any numbers which is allowed logically by date and time standards)
I get the error message "Wrong Syntax" even when i input the correct code. What seems to be the problem. Any help will be really appreciated Thank You So Much
It is because RegularExpressionAttribute expects a Regex pattern and you are providing a .NET string format pattern (MSDN: RegularExpressionAttribute Class).
For basic format validation you would need to use something like:
[RegularExpression(@"\d{2,2}/\d{2,2}/\d{4,4} \d{2,2}:\d{2,2}:\d{2,2}")]
Replace your string in your RegularExpression attribute with a real regular expression. Try one of these from this library site of regex's:
http://regexlib.com/DisplayPatterns.aspx?cattabindex=4&categoryId=5&AspxAutoDetectCookieSupport=1
Try the first one.
