How do you display the current date and time in a label in c#
You'd need to set the label's text property to DateTime.Now:
labelName.Text = DateTime.Now.ToString();
You can format it in a variety of ways by handing ToString() a format string in the form of "MM/DD/YYYY" and the like. (Google Date-format strings).
For time:
label1.Text = DateTime.Now.ToString("HH:mm:ss"); //result 22:11:45
or
label1.Text = DateTime.Now.ToString("hh:mm:ss tt"); //result 11:11:45 PM
For date:
label1.Text = DateTime.Now.ToShortDateString(); //30.5.2012
The System.DateTime class has a property called Now, which:
Gets a DateTime object that is set to the current date and time on this computer, expressed as the local time.
You can set the Text property of your label to the current time like this (where myLabel is the name of your label):
myLabel.Text = DateTime.Now.ToString();
labelName.Text = DateTime.Now.ToString("dddd , MMM dd yyyy,hh:mm:ss");
Output:
If you want to do it in XAML,
xmlns:sys="clr-namespace:System;assembly=mscorlib"
<TextBlock Text="{Binding Source={x:Static sys:DateTime.Now}}"
With some formatting,
<TextBlock Text="{Binding Source={x:Static sys:DateTime.Now},
StringFormat='{}{0:dd-MMM-yyyy hh:mm:ss}'}"
DateTime.Now.Tostring();
. You can supply parameters to To string function in a lot of ways like given in this link
http://www.geekzilla.co.uk/View00FF7904-B510-468C-A2C8-F859AA20581F.htm
This will be a lot useful. If you reside somewhere else than the regular format (MM/dd/yyyy)
use always MM not mm, mm gives minutes and MM gives month.
In WPF you'll need to use the Content property instead:
label1.Content = DateTime.Now.ToString();
label1.Text = DateTime.Now.ToLongTimeString();//its for current date
label1.Text = DateTime.Now.ToLongDateString();//its for current time

I'm using silverlight toolkit TimePicker for allowing the user to pick a particular time. I'm using the following code to convert the time to string,
String Time = Timepicker.Value.Value.TimeOfDay.ToString();
I get the value like "03:24:20", but i just want the value in hh:mm("03:24") format. How can i do that?
Thanks in advance.
If your time is 24hours, try:
Timepicker.Value.Value.TimeOfDay.ToString("HH:mm"),
else if your time is 12hours, try:
Timepicker.Value.Value.TimeOfDay.ToString("hh:mm"),
To be dynamic, try this ...
public DateTime timeValue { get; set; }
timeValue = timePicker.Value.Value;
<TextBlock Name="timeText" Text="{Binding StringFormat=hh:mm}"/>
timeText.DataContext = timeValue;
Hope this helps you. And to get a date value alone in TextBlock,
public DateTime dateValue { get; set; }
dateValue = datePicker.Value.Value;
<TextBlock Name="dateText" Text="{Binding StringFormat=d}"/>
dateText.DataContext = dateValue;
If you just want hh:mm format , then do the following,
DateTime? _datetime = Timepicker.Value;
String Time = _datetime.Value.Hour + ":" + _datetime.Value.Minute;
try with
String Time = Timepicker.Value.ToString("hh:mm", CultureInfo.InvariantCulture);
if you need 24-hour clock then use HH instead of hh
You better read the documentation on MSDN : Custom Date and Time Format Strings
In case of 24 hour format,the following works for me.
dtpStartTime.Value.ToString("HH:mm", CultureInfo.InvariantCulture);
I have a textbox and i would love it to be formatted. fortunately for me, i can get this done by changing the textmode = DateTimeLocal. Exactly what I want. Additionally, I would like to load this textbox with default values rather than leaving it with dd/mm/yy __:__:__ . I can change the text if it is a regular textbox (single mode) or even a datetime textbox. but i cannot change it with DateTimeLocal mode. some help please. thank you.
You will have to format the DateTime to a valid Date and Time string that can be parsed, here is one that works:
txtDateTimeLocal.Text = DateTime.Now.ToLocalTime().ToString("yyyy-MM-ddTHH:mm");
For more details on what other attributes you can set, see: http://www.whatwg.org/specs/web-apps/current-work/multipage/states-of-the-type-attribute.html#local-date-and-time-state-(type=datetime-local)
Try setting the whole datetime format including seconds and milliseconds, worked for me.
txtStartTime.Text = DateTime.Today.ToString("yyyy-MM-ddTHH:mm:ss.ss");
If you want to set a TextBox's DateTime dynamically from a database then you can use this code:
DataTable dtTemp = (DataTable)ViewState["DataSet"]; // this are temporary table
TextBox txtFromDate = (TextBox)gridEditBloackHomework.Rows[e.NewEditIndex].FindControl("txtFromDate");
TextBox txtToDate = (TextBox)gridEditBloackHomework.Rows[e.NewEditIndex].FindControl("txtToDate");
string c = dtTemp.Rows[e.NewEditIndex]["FromDate"].ToString();
DateTime FromDate = Convert.ToDateTime(dtTemp.Rows[e.NewEditIndex]["FromDate"]);
DateTime ToDate = Convert.ToDateTime(dtTemp.Rows[e.NewEditIndex]["ToDate"]);
DateTime dtFromDate = FromDate.AddHours(-2);
DateTime dtToDate = ToDate.AddHours(-2);
txtFromDate.Text = dtFromDate.ToLocalTime().ToString("yyyy-MM-ddTHH:mm").ToString();
txtToDate.Text = dtToDate.ToLocalTime().ToString("yyyy-MM-ddTHH:mm");
I have a DateTime picker to add arrival time to a list, I have 2 questions about it:
How can I get it to show dates like 12-Jan-2012 Instead of 12/01/12?
How can I get it to show the time after the date but not the current time, as thats what is shows atm.
My current code is not very advanced its just:
theVisit.ArrivalTime = DateTimePicker1.Value
Something like this will display the date and time:
DateTimePicker1.Value.ToString("d-MMM-yyyy hh:mm:ss");
To override the default DateTimePicker settings, you can do this:
DateTimePicker1.Format = DateTimePickerFormat.Custom;
DateTimePicker1.CustomFormat = "d-MMM-yyyy hh:mm:ss";
You can show a different time by modifying the format string, e.g.:
DateTimePicker1.CustomFormat = "d-MMM-yyyy 12:00:00";
or even
DateTime otherTime = DateTime.Now;
DateTimePicker1.CustomFormat = "d-MMM-yyyy " + otherTime.ToString("hh:mm:ss");
For it to show in that format in the picker, set the properties below
dateTimePicker1.Format = DateTimePickerFormat.Custom;
dateTimePicker1.CustomFormat = "dd-MMM-yyyy hh:mm:ss";
You're looking for DateTime Format strings. There's a great article on them on MSDN.
There's two types:
Standard DateTime Formats
Custom DateTime Formats
You can use these to construct the datetime to look how you want it to.
For your example, you would use :
DateTimePicker1.Value.ToString("dd-MMM-yyyy hh:mm:ss")
First, to alter how your DateTimePicker displays DateTimes:
DateTimePicker1.CustomFormat = "d-MMM-yyyy hh:mm:ss";
DateTimePicker1.Format = System.Windows.Forms.DateTimePickerFormat.Custom;
Your code:
theVisit.ArrivalTime = DateTimePicker1.Value;
Would not change, because the DateTimePicker1.Value isn't any different, it's just displayed according to your format.
If you want the control to display a specific time (not the current time), you have to give the control that value:
DateTimePicker1.Value = new DateTime(2012, 12, 21, 23, 59, 59);
Otherwise it will display the current time as of the form creation.
You may check datetimepicker like this to check if it is empty.
if(DatTimePicker1.Text.Equals(" "))
{
MessageBox.Show("DateTimePicker is empty");
}
I'm using the datetimepicker to get two dates. They are coming out like this: 24-11-2011..
I want to have them like this: 2011-11-24..
I've tried to accomplish this by doing this method, but its only changes the datetimepicker on the interface..
DateTimePicker1.Format = DateTimePickerFormat.Custom;
DateTimePicker1.CustomFormat = "yyyy-MM-dd";
This is my code. The output says 24-11-2011. I want it to say 2011-11-24.
string sta = dateTimePicker1.Value.ToShortDateString();
string en = dateTimePicker2.Value.ToShortDateString();
Console.WriteLine(sta);
ctrscan.getListOfDates(sta, en);
How can I do this?
thanks
The Value property of the DateTimePicker control will return DateTime type, not string.
To format this have such code:
string myDate = DateTimePicker1.Value.ToString("yyyy-MM-dd");
To change it "globally" change the default in the machine Regional Settings.
Change your System Date Format then only it will display correctly using Console.WriteLine(sta);
How to get the selected date of a MonthCalendar control in C# (Window forms)
"Just set the MaxSelectionCount to 1 so that users cannot select more than one day. Then in the SelectionRange.Start.ToString(). There is nothing available to show the selection of only one day." - Justin Etheredge
From here.
I just noticed that if you do:
monthCalendar1.SelectionRange.Start.ToShortDateString()
you will get only the date (e.g. 1/25/2014) from a MonthCalendar control.
It's opposite to:
monthCalendar1.SelectionRange.Start.ToString()
//The OUTPUT will be (e.g. 1/25/2014 12:00:00 AM)
Because these MonthCalendar properties are of type DateTime. See the msdn and the methods available to convert to a String representation. Also this may help to convert from a String to a DateTime object where applicable.
Using SelectionRange you will get the Start and End date.
private void monthCalendar1_DateSelected(object sender, DateRangeEventArgs e)
{
var startDate = monthCalendar1.SelectionRange.Start.ToString("dd MMM yyyy");
var endDate = monthCalendar1.SelectionRange.End.ToString("dd MMM yyyy");
}
If you want to update the maximum number of days that can be selected, then set MaxSelectionCount property. The default is 7.
// Only allow 21 days to be selected at the same time.
monthCalendar1.MaxSelectionCount = 21;
For those who are still trying, this link helped me out, too; it just puts it all together:
http://dotnetslackers.com/VB_NET/re-36138_How_To_Get_Selected_Date_from_MonthCalendar_control.aspx
private void MonthCalendar1_DateChanged(object sender, System.Windows.Forms.DateRangeEventArgs e)
{
//Display the dates for selected range
Label1.Text = "Dates Selected from :" + (MonthCalendar1.SelectionRange.Start() + " to " + MonthCalendar1.SelectionRange.End);
//To display single selected of date
//MonthCalendar1.MaxSelectionCount = 1;
//To display single selected of date use MonthCalendar1.SelectionRange.Start/ MonthCalendarSelectionRange.End
Label2.Text = "Date Selected :" + MonthCalendar1.SelectionRange.Start;
}
It'll be helpful if you want just to convert it by:
String myCalendar = monthCalendar1.SelectionRange.Start.ToShortDateString()
But if you want to get a formatted output you could instead:
String myCalendar = monthCalendar1.SelectionRange.Start.ToString("yyyy-MM-dd")
It's important to use year and day as lower caps, and month as upper or else it'll return you a wrong format, for example, if you do:
String myCalendar = monthCalendar1.SelectionRange.Start.ToString("YYYY-MM-DD")
it will return: YYYY-07-DD (If the original date's month was July)
private void monthCalendar1_DateSelected(object sender, DateRangeEventArgs e)
{
string clickeddate = monthCalendar1.SelectionRange.Start.ToString("dddd, dd MMM yyyy");
richTextBox.AppendText(clickeddate); //or whatever you decide to do with it.
}
SelectionRange property
