Is it possible to use DateTimePicker (Winforms) to pick both date and time (in the dropdown)? How do you change the custom display of the picked value? Also, is it possible to enable the user to type the date/time manually?
Set the Format to Custom and then specify the format:
dateTimePicker1.Format = DateTimePickerFormat.Custom;
dateTimePicker1.CustomFormat = "MM/dd/yyyy hh:mm:ss";
or however you want to lay it out. You could then type in directly the date/time. If you use MMM, you'll need to use the numeric value for the month for entry, unless you write some code yourself for that (e.g., 5 results in May)
Don't know about the picker for date and time together. Sounds like a custom control to me.
It is best to use two DateTimePickers for the Job
One will be the default for the date section and the second DateTimePicker is for the time portion. Format the second DateTimePicker as follows.
timePortionDateTimePicker.Format = DateTimePickerFormat.Time;
timePortionDateTimePicker.ShowUpDown = true;
The Two should look like this after you capture them
To get the DateTime from both these controls use the following code
DateTime myDate = datePortionDateTimePicker.Value.Date +
timePortionDateTimePicker.Value.TimeOfDay;
To assign the DateTime to both these controls use the following code
datePortionDateTimePicker.Value = myDate.Date;
timePortionDateTimePicker.Value = myDate.TimeOfDay;
Unfortunately, this is one of the many misnomers in the framework, or at best a violation of SRP.
To use the DateTimePicker for times, set the Format property to either Time
or Custom (Use Custom if you want to control the format of the time using
the CustomFormat property). Then set the ShowUpDown property to true.
Although a user may set the date and time together manually, they cannot use the GUI to set both.
DateTime Picker can be used to pick both date and time that is why it is called 'Date and Time Picker'. You can set the "Format" property to "Custom" and set combination of different format specifiers to represent/pick date/time in different formats in the "Custom Format" property. However if you want to change Date, then the pop-up calendar can be used whereas in case of Time selection (in the same control you are bound to use up/down keys to change values.
For example a custom format " ddddd, MMMM dd, yyyy hh:mm:ss tt " will give you a result like this : "Thursday, August 20, 2009 02:55:23 PM".
You can play around with different combinations for format specifiers to suit your need e.g MMMM will give "August" whereas MM will give "Aug"
Go to the Properties of your dateTimePickerin Visual Studio and set Format to Custom. Under CustomFormat enter your format. In my case I used MMMMdd, yyyy | hh:mm
You can get it to display time. From that you will probably have to have two controls (one date, one time) the accomplish what you want.
I'm afraid the DateTimePicker control doesn't have the ability to do those things. It's a pretty basic (and frustrating!) control. Your best option may be to find a third-party control that does what you want.
For the option of typing the date and time manually, you could build a custom component with a TextBox/DateTimePicker combination to accomplish this, and it might work reasonably well, if third-party controls are not an option.
If you need (24 hours) military time. You should use "HH" instead of "hh".
"MM/dd/yyyy HH:mm"

WHy does the value of calendar.SelectedDate include a time (eg.: 22-04-2022 00:00:00) when the user has picked a date?
In fact, I am interested in picking both a date and time but apparently, from what I've read, it seems like you can't pick a time from the calendar element in the program UI and I don't understand why when it also returns time in the value of Selected.Date
Is there an option to extend the calendar element to also include a timer-picker that isn't too complicated?
Code that that that returns returns dd-mm-yyyy 00:00:00
{
post.date = calendar.SelectedDate.ToString();
DateLabel.Content = $"Date and time for post: {post.date}";
}
WPF calendar has the default DateTime property. Neither only Date nor only Time it has Nullable<DateTime> default property, so it always along with Time. You would avoid it by setting below code
post.date = calendar.SelectedDate.Value.Date.ToShortDateString();
DateTime.toString() support formatting the date and time and this can be use to get only date not time as shown in the below code.
post.date = calendar.sele.ToString("dd-MMM-yyyy");
DateLabel.Content = $"Date and time for post: {post.date}";
WHy does the value of calendar.SelectedDate include a time (eg.: 22-04-2022 00:00:00) when the user has picked a date?
Simply because there is no date-only data type available in .NET and the Calendar control uses the DateTime type to store the selected date. That's why.
it seems like you can't pick a time from the calendar element in the program UI
Correct.

No.
I have a user request that I'm trying to accommodate, the simplest way I can think to explain is to use illustrate with a picture:
Essentially the user is typing a ton of dates in. Instead of typing the
MM [Backslash (Or Right Arrow)]
DD [Backslash]
YYYY [Backslash] etc ...
They'd like to Key the value and be moved to the next Date Part Value. While this doesn't seem like much I can imagine it adds up to allot of additional keystrokes and takes the end user off the number pad. I'm currently using Telerik's Winform RadDateTimePicker with Custom Format:
MM/dd/yyyy hh:mm tt
but would not be opposed to changing to the Winforms DateTimePicker.
Can anyone suggest an elegant solution for this ? The only thing I can currently think of is catching the keystrokes when the control is in focus but I feel like this could be messy.
Thankyou
RadMaskedEditBox (and respectively RadDateTimeEditor, which uses RadMaskedEditBox internally), have build in functionality to select the next part, however, it seems it does not work correctly with this mask, so I reported it as an issue. Here is the link to it: issue link. You can subscribe for status change alerts in order to get notified once its done.
What you can look at is the free form date time parsing introduced recently. It allows you to type in "10162014" which will get parsed to "10\16\2014". More information no parsing dates is available here: Parsing Dates
And the last thing would be to work with KeyDown and manually move the selection. There is API for this on the provider. Here is how to access it:
(this.radDateTimePicker1.DateTimePickerElement.TextBoxElement.Provider as MaskDateTimeProvider).SelectNextEditableItem();
I hope some of this works for you.
This is not intended to be a link answer but I have to refer to the Telerik documentation to allow the OP to customize the control according to his needs.
My understanding is that your customer needs to type the date and time in a specific culture avoiding to type the separators.
You should use the maskedEditBox which already have a mask for your need MM/dd/yyyy hh:mm tt
Particularly you should set the pattern "s" which correspond to "Sortable date time pattern (based on ISO 8601) using local time"
Have a look at Telerik documentation here to set up your control as needed and the relevant validator.
This should solve your problem.
This is how it looks when empty:
and this si show it appears when filled in:
Using the relevant event (I have used radMaskedEditBox1_Leave) you can still use also a dateTimePicker taking the input from the radMasketTextBox:
dateTimePicker1.Format = DateTimePickerFormat.Custom;
dateTimePicker1.CustomFormat = "dd/MM/yyyy HH:mm ss";
dateTimePicker1.Text = radMaskedEditBox1.Text;

So this seems like an easy thing to do, but still has me stumped. I want to display a list of strings to my user, based off of a few file's creation dates. So basically, display a list of DateTimes. The challenge is that want to use a custom format (something like 5/6/13 12:01 PM) but I want he date part of that to display differently based on how you have your system displaying the date (ie. a Brit would display that date as 6/5/13).
I thought I could just build two strings (one for date and one for time) and make sure that they date is region-formatted, but there is no default option for 5/6/13 (only 5/6/2013):
http://msdn.microsoft.com/en-us/library/az4se3k1.aspx
Next I hoped maybe the DateTime.ToShortDateString() function would work, but it displays as 5/6/2013 as well.
I know I can use a completely custom format like this: DateTime.ToString("M/d/yy h:mm tt") but I don't want to fix the date with the month before the day.
I suppose if I can' figure anything out then I could just build a custom datetime for America and for Europe and then query the OS for what datetime they are displaying in. But that seems really excessive. Any thoughts?
You could retrieve the current ShortDate format from current culture, change it and use it with ToString()
var currentDate = DateTime.Now;
var shortDateFormat = CultureInfo.CurrentCulture.DateTimeFormat.ShortDatePattern;
var newShortDateFormat = shortDateFormat.Replace("yyyy", "yy");
Console.WriteLine(currentDate.ToString(shortDateFormat));
Console.WriteLine(currentDate.ToString(newShortDateFormat));
System.Globalization.CultureInfo implements IFormatProvider, so you can provide a CultureInfo object as a parameter to the ToString method.
MSDN seems to have an example of exactly what you want.
C# problem ...I am recieving from a database a datetime type 1/1/1900 08:00:00 AM and I want to take only the time portion and populate three comboBoxes with HH MM (AM or PM). I have to do the same thing for two diffent sets of data I'm getting...Have no idea how to do it..
Can anyone help?
This is what i got for the moment...I am a newbie :0)
DateTime bh = Convert.ToDateTime(puf.GetResults["Begin_Hour"].ToString());
DateTime eh = Convert.ToDateTime(puf.GetResults["End_Hour"].ToString());
string bhs=bh.ToShortTimeString();
string ehs=eh.ToShortTimeString();
What you have ought to work fine to just get the time.
You could use the ToString() method which has an overload where you can give your custom formats. Refer to this MSDN link.
So you can use bhs.ToString("t"); to print the hour, minutes and AM/PM.
Use this (dt is your DateTime object)
bhs.Format("{0:t}", dt);
The result will be in your desired format:
"4:05 PM"
You can read more here: String Format for DateTime
If you're using objects/datatables, it might be a good option to just set the DisplayMember/ValueMember properties in conjunction with the FormatString property. Set the FormattingEnabled = true, FormatString = "t", DisplayMember = ValueMember = "[Begin_Hour|End_Hour]".
Note that [|] syntax is borrowing from Regex, meaning either value will work. Then just assign the underlying datasource to the ComboBox.DataSource property. It's usually a good idea to handle display/formatting on your UI elements and keep the data elements unchanged, which is why a lot of controls provide these various data display properties.
I have a datetime variable in my application. Its value is 01/09/2010 00:00:00. I want to get value of 01/09/2010. Still I want to use the DateTime structure. Is there any method/property for that. I know it is possible using conversion.
For example I have
DateTime date = new DateTime(2010,09,01);
It will display 01/09/2010 00:00:00
I want date to be 01/09/2010 alone.
Is it possible?
Call date.ToShortDateString() so see only the date part of the DateTime object.
To force a specific format (if that is not your default culture format), you can use
date.ToString("dd/MM/yyyy");
Note that Im not sure if 01 or 09 is the month in your example. If I have mixed them up, just replace "dd/MM/yyyy" with "MM/dd/yyyy"
Are you looking for a way to format the date for display/printing purposes, or to get rid of the time part if it is given?
Use the DateTime.ToShortDateString() method or the DateTime.Date property, respectively.
