I have an ASP.NET form(MVC3/Razor) and on the the form I want to alter how a date field displays from a datetime field. I.e. in some of the data columns the time is significant and I want the date and time to show, in others it is irrelevant and I just want the date to display. Is this possible?
Thanks in advance

Two ways: 1) Using a UIHint attribute to tell the field whether or not to render as a Date or DateTime and then having an EditorTemplate to differentiate the two. Or 2) Use the EditorFor extension method and tell it explicitly which EditorTemplate to use.
The same can go for DisplayTemplates when you want to truncate the time.
Here's an example from SO: ASP.NET MVC Editor-Templates/UIHint with parameters
You can use String.Format to format the date and time in exactly the way you want.
string.Format("{0:dd-MMM-yy}", yourDate);
http://msdn.microsoft.com/en-us/library/8kb3ddd4.aspx
You can format each appropriate column as you want. For example:
#string.Format("{0:MM/dd/yyyy}",DateTimeField)
and/or
#string.Format("{0:MM/dd/yyyy hh:mm:ss}",DateTimeField)

I want to get the date in this format -
MM-dd-yy.
For example: 10-12-23
I'm writing this code but don't getting the desired solution -
{<entity_name>:<attribute>/#date;} Check-In Link
What should I write in the date part?
I'm afraid the only way to make it work is to set the user's locale to a locale that uses MM-dd-yy format.
Alternatively, it's possible to create a custom string field, populate that field with a properly formatted date and use the value of it in your template.
Google Forms I need Pre-filled current Date & current Time Entry in date and time fields of my google form. How to do it
My solution is to make the Date field optional. The default is to assume the todays date which is what you get from the timestamp field. In case it needs to be anything else you can enter it manually.
A simple code-free solution is to make separate sections in your form and use the feature that routes users to different sections based on responses. The first section asks whether the form is for the current date/time. If yes, you use the timestamp as the date and time and route the user to the main section with your questions. If not, route them to a section to set the date and time, and then after that route them to the main section.

-Google Forms has updated how dates are passed through URL parameters.
Instead of passing each component of a date as a separate param, you now pass them using the same syntax as all other fields using the YYYY-MM-DD format for your date value.
Here is an example URL:
`https://docs.google.com/forms/d/e/${formId}/viewform?usp=pp_url&entry.${dateEntryFieldID}=${YEAR}-${MONTH}-${DAY}`
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.
I have a table that contains three columns.
"UserId" type-nvarchar
"PostAuthorId" type-nvarchar
"Post" type-text
This table will contain "wall" posts like in facebook for each user's page. I am going to use a gridview on each user's page to display the posts. The issue is I want to display them with the latest(most current) post being first and the earliest post being last.
I have never used autoincrement before and I am not sure if that is the answer. If it is, I do not know how to use it. I thought about adding a date posted column and then ordering by date.
If I end up using the date column, I could also display the date on the post. Is there a way to convert the date to a readable format?
What is the best way of implementing this type of ordering?
If you use AutoIcrement the first record will start with 1 and each record will increment from there. (default setting)
If you want to sort them by newest first do an ORDER BY ID DESC
I would suggest making a column called wallPostID then setting that to AutoIncrement and also your Primary Key
Date Formating:
If you are displaying this data in a gridView
Go to Edit Columns on your grid view
CLick on the Date field under "Selected Fields" on the bottom left
Under "BoundField properties" on the right Go to Data -> DataFormatString
{0:d} will display as 1/1/2010
This site has more info in string formatting

A datetime column would definitely work for something like this. Assuming you are using MS-SQL, you can also attach a default value to the column using a built-in function like GETDATE(). That way, you only have to input the data that matters and the database will take care of adding the datetime column.
For converting a datetime to a readable format try:
DateTime postDate;
string value = postDate.ToShortDateString();
You should always use an ID field that auto increments. Can also be used as your PK
I would suggest the DateTime field rather than the autoincrement simply because it will not only serve as an effective Sort field, it also preserves information that you may well want to display. If you want the most recent first you'll sort using the Date and a "DESC" modifier:
Select ... Order By [Date] DESC;
When you retrieve the data, you can retrieve it as a DateTime and modify it using C#. You can use "ToShortDateString()" as suggested by mdresser if you just wish to show the date or ToString("...") if you wish to show the time as well. You can also use SQL to convert it into a string before retrieving it:
convert(Varchar(10), #mydatetime, 101)
If you look in MSDN you'll see the various conversion codes (101 is the code used above) that can be used to translate the date in various ways.
UPDATE: You may want to use an autoincrementing field for your application for reasons other than your expressed need to sort wall entries. They are easy to use - just mark the field as an Identity if using SQL Server (other DBs are similar). As far as using them in your program, just think of the field as an Int field that you never have to set.
Now, why would you use a auto-incrementing field? Perhaps the most straightforward reason is so that they give you have an easy way to identify each record. For example, if you permit people to alter or delete their wall entries, the auto-incrementing field is ideal as it gives you a way to easily look up each record (each record will be assigned its own, unique value). You might put an "x" next to the record like StackOverflow does and make it a call back with the UID (auto-increment) value. Note that you should set up your primary key on the UID field if you'll be doing this.
Now, if you find them useful for this reason then you could also sort by the UID. I would still store the date so that you can provide Date and Time feedback as to when an entry was made on the wall but this would no longer be your indexed or sorted field.
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.
