I am trying to validate some textfields for decimal values and i am using regex to that.Here the expression that i am using currently. @"d.dthis works fine for examples 45.23, 455.345 ...But not these (45.23, 45.23abcd . its still allowing these.Looks like its only checking for the decimal text in between , start and end seems to be pretty for garbage characters.I tried putting ^ in the begining of the expression and $ in the end. But didnt make a difference.
@"^(d*(.d{1,4})?)$" It should allow positive numbers with an optional decimal, and 1-4 digits after. So values like 2 22 2.2 2.222 .2 .56 0.64
If I use that regex with Regex.IsMatch, it works as I expect. However if use it as a RegularExpressionAttribute data annotation, It will not accept .2, as being valid. It will accept 0.2, and it will 2, 2.22, etc but it will not allow me to lead with a decimal place. I can hack around it by applying a javascript onkeydown event to add a 0 to front if you lead with a decimal.... Am I missing something here? Does the .net double type it backs into not support leading with .2 or is the jquery validation broken or what???
I am doing the music store tutorial, and I discovered a problem, I don't know how to solve this. I am in Argentina, and our decimals have this format: '0.000,00' instead of the american format: '0,000.00'. I add the:
[Code]....
But now in the form when I write a number in this format '00,00' It shows me the message "Price must be between 0.01 and 100.00", but if I change that number to one in the '00.00' format, the client validator is hidden and It allows me to save, but then the server validation returns the following message: "The value '34.34' is not valid for Price." Cause when trying to save It must be waiting for a 00,00 formatted number. So...

I was read your post: "Export GridView to Excel in ASP.Net with Formatting using C#" and is very useful. That code works perfect. But I need create a new format for a specific column in my sheet before to export it. For example:My DataTable have a column with decimal numbers and I'm trying reduce the tenths for each number.I want this: 2,874444 ----> 2,87 for a specific range. In this case I need it for all numbers in the column 13 or well said for the Column called N in Excel. Only reduce two tenths.

The answer of which should add on 0.5 to the original value. If I were to use the increase value of 60 which then becomes 60/60 it will work.I'm dividing by 60 because the increase value is per hour so I make it smaller to get per minute value. Why is it doing this?
I have a web application (done in ASP/C#) that has regex validation on a text box. Initially the regex works perfectly fine. But then I also provide a button click event (clear) that allows the user the clear text box and change their input for a new query. At this point (page post back) the regex takes control and maintains control of the text box so a new query can't be run. Can anyone tell me what to do so that the regex doesn't fire on page postback and allows new input for validation?

I'm having a little trouble with using regex in linq. I want to be able to perform a search on values in my database. The goal is to insert a value into the regex and then use that to search a column in a table in my database for that term. I want it to work so that it gets all exact matches and also returns matches in which the search term is a substring of the term in the column.

I want a text box which will accept CSV values and the values can be any time of a day,i.e.,in one text box I can enter multiple clock times,separated by comma.Hour,Minutes will be separated by :.Second no required
