I have a text box for Registration Number and i want it to use the following format 2013/123456/25. I want to validate for in-correct format using Regular Expression Validator.
The exact format must be first 4 numbers/6 numbers/2 numbers -->(2013/123456/25)
Thank you for your help...
You could use something like this :
^\d{4}/\d{6}/\d{2}$

I would like to format this kind of number:
1234567.99 (obviously all thousands digits are optional)
In this way: 1.234.567,99
I know it is possible with Eval, but I didn't find an useful guide to do this.
Could you help me?
Thanks
There is an overload of Eval that takes three parameters (the link also contains a sample):
Container
Expression
Format
For the format, you'd specify "{0:c}" or whatever format you like. For a list of the Standard Numeric Format Strings, see this link. If you want to specify your format with a custom format string, e.g. use "{0:#,##0.00}".
You can use the ToString() extension
var value = 1234567.99;
Console.WriteLine(value.ToString("C3", CultureInfo.CurrentCulture));
Or by stating your culture
Console.WriteLine(value.ToString("C3", CultureInfo.CreateSpecificCulture("sv-SE")));
I need to use the RegularExpressionValidator. It has to check the correct format. I have found this nice working expression:
^(((0[1-9]|[12]\d|3[01])\/(0[13578]|1[02])\/((19|[2-9]\d)\d{2}))|((0[1-9]|[12]\d|30)\/(0[13456789]|1[012])\/((19|[2-9]\d)\d{2}))|((0[1-9]|1\d|2[0-8])\/02\/((19|[2-9]\d)\d{2}))|(29\/02\/((1[6-9]|[2-9]\d)(0[48]|[2468][048]|[13579][26])|((16|[2468][048]|[3579][26])00))))$
But I need this Expression not for dd/mm/yyyy. My date format should be dd.mm.yyyy.
How to transform this expression?
try it
/^(?:(0[1-9]|1[012])[\. \/.](0[1-9]|[12][0-9]|3[01])[\. \/.](19|20)[0-9]{2})$/
or
^((((0?[1-9]|[12]\d|3[01])[\.\-\/](0?[13578]|1[02])[\.\-\/]((1[6-9]|[2-9]\d)?\d{2}))|((0?[1-9]|[12]\d|30)[\.\-\/](0?[13456789]|1[012])[\.\-\/]((1[6-9]|[2-9]\d)?\d{2}))|((0?[1-9]|1\d|2[0-8])[\.\-\/]0?2[\.\-\/]((1[6-9]|[2-9]\d)?\d{2}))|(29[\.\-\/]0?2[\.\-\/]((1[6-9]|[2-9]\d)?(0[48]|[2468][048]|[13579][26])|((16|[2468][048]|[3579][26])00)|00)))|(((0[1-9]|[12]\d|3[01])(0[13578]|1[02])((1[6-9]|[2-9]\d)?\d{2}))|((0[1-9]|[12]\d|30)(0[13456789]|1[012])((1[6-9]|[2-9]\d)?\d{2}))|((0[1-9]|1\d|2[0-8])02((1[6-9]|[2-9]\d)?\d{2}))|(2902((1[6-9]|[2-9]\d)?(0[48]|[2468][048]|[13579][26])|((16|[2468][048]|[3579][26])00)|00))))$
It look like only thing that need to be changes is all \/ to \. so it should be
^(((0[1-9]|[12]\d|3[01])\.(0[13578]|1[02])\.((19|[2-9]\d)\d{2}))|((0[1-9]|[12]\d|30)\.(0[13456789]|1[012])\.((19|[2-9]\d)\d{2}))|((0[1-9]|1\d|2[0-8])\.02\.((19|[2-9]\d)\d{2}))|(29\.02\.((1[6-9]|[2-9]\d)(0[48]|[2468][048]|[13579][26])|((16|[2468][048]|[3579][26])00))))$
I have a textbox called period which should allow the user only to enter the string as YYMMDD format. YY can be numbers from 0-99, MM from 1-12 and DD from 01-04.
I want to use regular expression to get this done. Please help me with the expression to achieve this.
Try this "^[0-9][0-9][0-1][1-2][0][1-4]$" the error in your expression is that it will accept: 991214 which is incorrect.
\d\d(?:0[1-9]|1[012])(?:0[1-4])
matches 110701
does not match 110705
I have a regular expression validator on a text box to validate that the text entered is a valid date.
See reg ex below:
ValidationExpression="^[0-9]{1,2}/[0-9]{1,2}/[0-9]{4}$"
Now I want to allow the following in the textbox: mm/dd/yyyy
How can I update my regex so that if mm/dd/yyyy is entered it does not throw a validation error?
Thanks in advance.
ValidationExpression="^[0-9m]{1,2}/[0-9d]{1,2}/[0-9y]{4}$"
Basically allows 0-9 or m in the first field, 0-9 or d in the second, 0-9 or y in the third (in regular expression [] brackets contain a list of possible options, - denote ranges of values when placed within brackets).
This is a more accurate way to restrict the Date to a more meaningful format
^[1-12]{1,2}/[1-31]{1,2}/[2000-2050,1900-1999]{4}$
This is still not perfect as this will allow - for instance - a date 02/31/2013.
Just realized this is quiet buggy.
i have a gridview that shows some indicators.one of the numbers is a computed percentage it looks like this "33.33333333333333333333333333333333333333" i tried to set the DataFormatString property of the column to several different formats such as "{0:P}" ,"{0:D}" and "{0:##.##}" but nothing worked for me to show it like that "33.34". Any ideas?
What happens if you use "{0:F2}"?
Try entering just the format string without braces and the index,eg. P, D or ##.### . The braces and index are used by String.Format, where there are more than one format parameters. ToString methods (e.g. int.ToString) and control format parameters use only the format string without braces
