![]() The last thing you need to do is to update the "defaultDate" variable when the user selects a new date in the picker's calendar (so that the variable reflects what the date picker is showing, and incrementing / decrementing the date will produce the correct result): DatePicker1.OnChange: Set(defaultDate, DatePicker1. ![]() The Get-Date cmdlet returns the current date as a DateTime object. The last thing you need to do is to update the "defaultDate" variable when the user selects a new date in the picker's calendar (so that the variable reflects what the date picker is showing, and incrementing / decrementing the date will produce the correct result): DatePicker1.OnChange: Set(defaultDate, DatePicker1.SelectedDate) The command uses the Date parameter to specify the date. In the date picker, you then set its Default property to the "defaultDate" variable, so that when that property is changed (by clicking the previous/next buttons), then the date displayed in the picker will be changed as well. Now you can add the two buttons (prev/next) and set their properties to update the value of that property: Button1.Text: "Previous day"īutton1.OnSelect: Set(defaultDate, DateAdd(defaultDate, -1, Days))īutton2.Text: Set(defaultDate, DateAdd(defaultDate, 1, Days)) Moreover, write a test program to test your class. Add a member function, isLeapYear, to check whether a year is a leap year. You may also notice that the month of July is represented by 6, not the usual 7. Rewrite the definitions of the function setDate and the constructor so that the values for the month, day, and year are checked before storing the date into the member variables. However, the order cannot be changed, so keep that in mind if you decide to leave off a number. If any number is missing from the Date creation, it will default to 0. In the app's OnStart property (you can find it on the first screen of your app), you'd need to initialize that value. In the date and time method, our seconds and milliseconds are set to 0. The current day of month will have an impact on the behavior of this method. ![]() For example, if you use 15 for monthValue, the year will be incremented by 1, and 3 will be used for month. You can use a global variable to store the date that is bound to the Default property in the date picker, and in the prev/next buttons you'd decrement/increment the variable value. If a parameter you specify is outside of the expected range, setMonth () attempts to update the date information in the Date object accordingly.
