I am working on asp.net mvc3 and i want a particular requirement that the mvc validation uses numbers from 0-99 so that i have the regex as
[RegularExpression("[0-9]{1,2}$")]
Now i want a particular requirement that the numbers from 0-9 must pass validation if it is typed as 01,02,....,09 and the rest of the numbers between as 10-99 should pass validation as a two digit number.
Please help me on this regex. I have googled it but to no avail.
can anyone suggest a regex for this type.
Just matching
"[0-9][0-9]"
should fit your requirements exactly.
It only matches if single numbers are typed in the form of 01; 02; 03 etc and matches all two digit numbers

I have a sheet I use as a database of scientific papers. I copy journal article titles from different sources (some could be from an email, others are links on a web page, or just the title from the article page). I have conditional formatting set to let me know if I'm adding a title that is already in the list. I've noticed that there are some titles that are "ignoring" the conditional formatting, and it looks like there are hyphens in all of the offenders. If I remove the hyphens, the conditional formatting works. So there is some 'difference' in the hyphens originating from the same title that is preventing the conditional formatting from viewing them as identical.
Shared sheet
Examples of offending titles:
End-to-end continuous bioprocessing: impact on facility design, cost of goods and cost of development for monoclonal antibodies
End‐to‐end continuous bioprocessing: impact on facility design, cost of goods and cost of development for monoclonal antibodies
End‐to‐end continuous bioprocessing: Impact on facility design, cost of goods, and cost of development for monoclonal antibodies
What is this difference, and is there a way to fix it? Do I need to write a script to find/replace the hyphens to get this to work?
TIA
Just because characters appear identical, it does not mean that they are identical. You have fallen foul of the similarity between the hyphen and dashes. Visually, they are almost identical - dashes are slightly widest than the hyphen.
Dashes are regarded as "special characters" (i.e. they aren't keys on the keyboard) but they are used widely in html. So if, for instance, you copied an item from a website then you might unwittingly have copied dashes rather than hyphens.
You can identify the exact nature of a character by using the CODE function.
You ask "What is this difference, and is there a way to fix it? Do I need to write a script to find/replace the hyphens to get this to work?"
WHAT IS THIS DIFFERENCE?
It's important to recognise that though these examples appear identical, there are other differences that are more than just hyphens vs dashes.
Example#1 - Hyphen - CODE returns "45"
Example#2 - Dash - CODE returns "8208"
Example#3 - Dash - CODE returns "8208".
But there are other factors that contribute to fail to trigger the conditional formatting rule:
Length = 128 (vs 127 for the other examples). There is an additional comma (after "cost of sales")
the word "Impact" is spelled with an upper case "I" (lower case for the other examples)
MOVING FORWARD
Do you need a script? No (IMHO)
Is there a way to fix it? As outlined above, there are more differences that just hyphens and dashes. And, as time goes by, the number & type of difference might increase. However, there is a solution to the "Hyphen Vs Dash" problem which is the focus of this question.
FORMULA AND FORMATTING
Your data is currently in Column A and Column A is also subject to conditional formatting.
Remove the conditional formatting rules from Column A
Insert this formula in cell B2
=arrayformula(if(LEN($A2:A)-LEN(SUBSTITUTE($A2:A, char(8208), ""))=0,A2:A,arrayformula(substitute(A2:A,char(8208),char(45)))))
Conditional Formatting for Column B
select the range in Column B
select, Format, Conditional Formatting.
Select "Custom Formula is" and enter this formula: =countif($B$2:$B2,B2)>1
Select a preferred Formatting Style and then click Done.
FORMULA LOGIC
arrayformula enables the formula to automatically populate all the relevant cell in the column.
LEN($A2:A)-LEN(SUBSTITUTE($A2:A, char(8208), ""))=0
a test for dashes in a string. It substitutes a nil value for any/all instances of a dash (char(8208)), then compares the length to the adjusted length. If the value is zero, then there are no dashes in the string.
IF: Test for any dashes,
if the string doesn't contain any dashes then use that value
else, the string must contains dashes so substitute any dashes for hyphens, and use the substituted value
arrayformula(substitute(A2:A,char(8208),char(45)))
The conditional formatting rule then looks for duplicate values in the column, and formats any/all duplicate values.
You'll note that Example#3 is not flagged as a duplicate despite containing dashes. This is because of the spelling of "Impact" and the extra comma after "cost of sales".
Sample
using mvc kendo grid to represent the dat
I have decimal values likes
Actual O/P
61.05
16.00
15.92
Expected O/P This is What i am looking for
61.05
16
15.92
I used to display the value like this
Format("{0:n2}")
How can I achieve expected o/p, with the help of kendo format
Strange, that should actually work.
You can try the following formatting string as an alternative solution: {0:0.00}.
Format("{0:n2}") will force all input numbers to 2 decimal places. If you want to apply decimal places based on the value, use Format("0:0.##}") (where the number of decimal places (#) is the maximum number of decimal places you will have).
If you don't need the column to be numbers (for example for sorting, filtering or summing in the grid), then pass string values to the column and do the unusual formatting requirement in the controller.
I am trying to validate fields in my iOS program:
I need to match a phone number, but the field is optional.
I thought using the regex to match the number to also validate if there is no phone number:
[0-9\-\+\*]{4,14}
Then I thought how to also match where there is either a valid number or no number at all?
(:?[0-9\-\+\*]{4,14})?
Meaning, either match between 4 to 14 chars within the range 0-9,+,-,* or nothing.
This website is showing infinte matches for that pattern.
ideas?
^$|^[0-9\-\+\*]{4,14}$
As to the questions this has brought here:
Regex is a great validation method. and it is cross platform.
no need for another layer of code to implement. Simple and clean.
You should just code it. I don't know your language but basicaly :
If(field.isEmpty)
should do the trick.
I'm using String.Format("{0:####.00;(####.00);0.00}", Model) to display a negative currency of -1600.00 as (1600.00). However, decimal inputs in this format cannot be parsed by the model binder.
I suspect I need to change a culture setting, but I don't know where.
How do I tell my ASP.NET MVC 3 application that a decimal form input value of (1600.00) means -1600.00?
Solved. See answer below.
Solved by keeping my display templates' formatting and changing my editor templates to use a standard minus without parentheses.
For north american phone numbers, (999) 999-9999 works pretty well for an input mask.
However, I can't find a good example that will handle non-north american numbers. I know that the number of digits can vary, so other than restricting it to digits only, is there a good example anywhere?
There is no generic mask, really: There are too many combinations.
The only thing that is fixed is the international country code, usually prefixed by +.
According to the Wikipedia Article on telephone numbering plans, most countries conform with the E.164 numbering plan.
If I read E.164 correctly, you can safely make the following assumptions:
Country code: 1-3 digits
Network / Area code and Number: Up to 19 digits
I would ask for the country code, and have the "area code + number" field as a 19-digit input.
You can deduce the country code with a simple RegEx such as:
^(?:(?:0(?:0|11)\s?)|+)([17]|2([07]|[1-689]\d)|3([0-469]|[578]\d)|4([013-9]|2\d)|5([1-8]|[09]\d)|6([0-6]|[789]\d)|8([12469]|[03578]\d)|9([0-58]|[679]\d))
Followed by
(([\s\(\).-]{0,2}\d){4,13})$
to extract the national number.
For validating the national number length and validity, you'd need libphonenumber or similar.
The long RegEx above allows +, 00 or 011 before the country code and a selection of punctuation in the number which will also have to be stripped.
You don't mention your application but this is certainly possible using regular expressions. You might want to take a look here.
Not easily. Take a look at this page for an example why: if you only look at the German phone numbers, you'll note that there are different formats depending on where you're calling the number from. Which one do you pick? And that's just for German phone numbers; they differ from continent to continent, and from country to country.
Going with "numbers-only" is probably your safest bet.
I would allow for spaces, dashes, slashes and all that, but actually only care for numbers and the optional leading + sign. Everything else, such as assuming certain blocks of a certain length is just asking for trouble.
May be it is bad to answer an old question. But libphonenumber seems like a good solution to your question.
