I'm new to date timepickers. I was wondering if someone could explain them to me properly. I have a booking system that you must be able to book a date and specific time in the future and reserve that time frame in a sql database. Can I do it with date timepickers? It has a nice interface when its on my form but I cant see a way for the user to set the time? it always just gives me the default time. Any help? thanks

Date Time pickers are pretty useful to use when you want people to be able to visually select a date/time. once the user selects a datetime, you can access it like this

int mymonth = this.datetimepicker1.Value.Month
int myday = this.datetimepicker1.Value.day

etc...

Furthermore, you can use events to trigger when stuff happens with them. So for instance, they select a date, you can use the ValueChanged event to make other fun stuff happen too.

  • added a picture of my form to the post. will that work? where i use your idea of adding a myday, mymonth and myyear and then getting the time manually with comboboxes? isnt there a built in way seeing that its called a dateTIMEpicker:P – Andrea Visnenza Andy Oct 24 '13 at 15:54
  • If you set the format to time, then they can choose the time by entering it in, and choose the date by clicking on the day picker icon like normal. dateTimePicker1.format = DateTimePickerFormat.Time – metinoheat Oct 24 '13 at 15:54

The DateTimePicker-Control has a Format-Property, which will set the format of the date and time displayed in the control. AS stated in this answer you can use following format to show Date and time:

dateTimePicker1.Format = DateTimePickerFormat.Custom;
dateTimePicker1.CustomFormat = "MM.dd.yyyy hh:mm:ss";

Here you can get a list of all format string and their descriptions: List of CustomFormat-String

The result will look like this:

DateTimePicker Custom Format

.NET also has a structure called DateTime to save your selected value. You can save it with following code

DateTime yourSelectedDateTime  = dateTimePicker1.Value;
textBox1.Text = yourSelectedDateTime.ToString();

  • thanks :) but what i want to know is there any way in the dateTimepicker to let the user physically define the selected time on the date? or must it be programmed manually into variables? – Andrea Visnenza Andy Oct 24 '13 at 15:56
  • Unfortunately you can only pick Dates with the DropDown of the DateTimePicker-Control. But you can raise and decrease every part of date and time with the arrow-keys or if you set the `ShowUpDown = true;` with two buttons (See here: http://www.dotnetperls.com/datetimepicker-2.png). But if you set ShowUpDown to true you'll have no DropDown-Menu anymore – Daniel Abou Chleih Oct 24 '13 at 16:06
