Hello everyone,

I have simple WPF application, and I need to let user choose value from Calendar and then work with the day only. For example, user chooses date 06/08/2020, so I need to take the "06" value and assign it to int variable, then work with it in some mathematical equations.

Unfortunately I did not find on the interner, how to exactly do it. When the user enters number into textbox, its quiet easy, you just state the variable and put the TextBox.Text as a value, like int x = int.Parse(TextBox1.Text);


Can you guys help me on this?

What I have tried:

I was trying some variations like this

int day = Calendar1.SelectedDate.Day, but non of it worked

Thank you very much

WPF Date Picker control:

Quote:
A DatePicker is a control that allows a user to pick a date value. The user picks the date by using ComboBox selection for month, day, and year values

Reference: WPF - Datepicker - Tutorialspoint[^]

Sample:

C#

private void DatePicker_SelectedDateChanged(object sender, SelectionChangedEventArgs e) { 
     var picker = sender as DatePicker;  
     DateTime? date = picker.SelectedDate;
		
     if (date == null) { 
        this.Title = "No date"; 
     } 
     else { 
        var daySelected = date.Day; // Day from the selected date
     } 
  }

The Calendar has a SelectedDate property - which returns a DateTime value.
So you can get the day of the month from that as normal:

C#

DateTime dt = myCalendar.SelectedDate;
int dayOfMonth = dt.Day;

If that doesn't work, then either the user hasn't selected a date (use DateTime.HasValue to check that) or he has selected multiple dates, in which case you probably want to look at the Calendar.SelectedDates collection instead and decide which one to use.
