How to trim datetime string to its minute in GridView? - asp.net

I have bound fields in GridView to some dateTime property of data objects. The fields are displayed to the seconds level. It looks like 2009-2-3 18:00:00 PM.
I just want it displayed to the minutes, e.g 2009-2-3 18:00.
What is the best way to do this?
Edit:
I find use DataFormatString="{0:g}" is fine for me.
The format is 2009-2-3 6:00 PM.

Although you have found a solution, here's some additional information:
You can find a list of all standard date and time format strings (such as "g") on this page in MSDN: Standard DateTime Format Strings.
And if do not want to use one of the predefined formats, there is also a page about Custom Date and Time Format Strings. For example, to get a date exactly in the format you used in your question ("2009-2-3 18:00") you could use the format string "yyyy-M-d HH:mm".
Before using a custom format string, remember that using the standard (predefined) format strings has the advantage that it automatically takes into account the current culture (regional settings). So if you want to display the date to users, probably a predefined format will be the better choice.

Get Short Date Format/Style/Structure

Suppose my system date is 2014-02-10 & I have published my app on Internet Information System. Now Using DateTime.Now.ToShortDateString method I can get date like 2014-02-10, but how can get pattern/style/structure (e.g yyyy-MM-dd) for date? It should be irrespective of current culture.
IF I change date to 10-Feb-2014, then I should get dd-MMM-yyyy.
What's the solution? Thanks in adv..
Ah, I see. I thought you were saying that you wanted to format a date value but it seems that you're saying that you actually want the format string. In that case, you need to use get an appropriate DateTimeFormatInfo object and get its ShortDatePattern property. You can use System.Globalization.CultureInfo.CurrentCulture.DateTimeFormat or System.Globalization.CultureInfo.InvariantCulture.DateTimeFormat to get that DateTimeFormatInfo.

Symfony 2.1. How can I display a single_text time field in 12 hour am/pm format?

I have a time field on my form with widget set to 'single_text'.
My US users will want 12 hour am/pm format.
http://symfony.com/doc/current/reference/forms/types/time.html#widget
Although it's not entirely obvious, that accepts an input of 2:15pm but if the form returns because of a validation error on another field or is later opened to edit an existing record then it displays 14:15 which of course is correct but is probably off-putting.
How do I get it to display 2:15pm? I don't see an option to do that.
Well, this turns out to be harder than it should be. The problem is that the Time form type does not allow you to specify a format like the Date form type does and the format it uses is H:i. Yes, 24-hour format :-(
So, the only solution is to build your own form type which uses the h:i format. You can find instructions for how to build your own form type here:
http://symfony.com/doc/2.1/cookbook/form/create_custom_field_type.html
Then you can use the Time form type as the base for your form type and just change the format it uses. The Time form type can be found here:
/Symfony/Component/Form/Extension/Core/Type/TimeType.php

Control input of SQLite attribute to date format only.

I have been reading all about converting TEXT fields into date formats and ways to use Python to create date objects but my question remains.
My table has a dateTime column that is specified as TEXT, I would like to build a constraint that forces input to be in dateTime format, but as SQLite doesn't do dates (as I would like) I haven't worked out how to do it.
My current ideas: 1. Limit number of characters
2. Set separate attributes for day, month and year and constrain their domains
3. It is silly to do this on the database side just do it in the user interface
I would appreciate your opinions on these or other options.
Thanks :)
I've been trying to solve the same issue and the method I came up with was to use the date/time functions to parse the value and check that it hasn't changed. Essentially the following:
CREATE TABLE dts_test (
dts TEXT CHECK (dts IS datetime(dts))
);
If the default format is not what you want you can use the strftime or similar to design whatever format you want, but it must be something that the built-in date and time functions can parse.

Specifiy date type used by fullcalendar

The date/time format fullcalendar uses is kind of weird. I want to specify during the created of the calendar or somewhere in the parameters a datetime of MM/DD/YYYY HH:MM PM/AM. Is there a way I can do this. I read about formatdate, but didn't get any information about this
fullCalendar has "parseDate" and offers three methods:
The string may be in ISO8601 format, IETF format, or a UNIX timestamp (in either integer or string form).
Your "MM/DD/YYYY HH:MM PM/AM" seems not to match one of them.

To retrieve Date in the same format as stored

I am facing an issue in my Flex application.
I am creating some array collections and storing date objects in it.In the later part of the application I will create 'advanceddatagridcolumns' with these array collections as the data sources.
Initially while creating the Array Col , I do have the 'formats' given by user, for each array collection eg. '1995/06/25' but in the later part I have no access to these formats. I want to display this dates in the data grid in same way as the user has specified. Right now, it displays it in the default format 'Sun Jun 25 00:00:00 GMT+0530 1995' instead of '1995/06/25'.
I have a common 'labelFunction' for these advancedatagridcolumns, and thus I can not use the DateFormatter as I 'formatstring' would be different for different columns.
So is there some way to display/retrieve the date in the same format as stored and not in the default way. Or while creating the date object can't I specify that I would always like it to be returned in some desired format.
The Date class in Flex as far, as my experiences go, is not very versatile. My hunch is that this is by no means possible with the regular framework capabilities.
However, if the date does not need to be changed after the user has input it, you might just want to save it as String and only create a temporary ArrayCollection of Dates for displaying them. This way you don't need to worry about the format changing because you're saving the original value.
How are you parsing the dates anyway? I mean that are you finding out the format yourself with RegExps or such, or using the parse method of the Date class?
just create a labelfunction specific to that column only and then you can use the formatstring
