Xamarin datetime picker

Download the sample. The Xamarin. Forms TimePicker invokes the platform's time-picker control and allows the user to select a time. TimePicker defines the following properties:. All of these properties are backed by BindableProperty objects, which means that they can be styled, and the properties can be targets of data bindings.

The Time property has a default binding mode of BindingMode. The TimePicker doesn't include an event to indicate a new selected Time value. If you need to be notified of this, you can add a handler for the PropertyChanged event. In code, you can initialize the Time property to a value of type TimeSpan :.

When the Time property is specified in XAML, the value is converted to a TimeSpan and validated to ensure that the number of milliseconds is greater than or equal to 0, and that the number of hours is less than The time components should be separated by colons:.

Because the Time property has a binding mode of TwoWayany new time that the user selects is automatically propagated to the ViewModel. If the TimePicker does not contain a binding on its Time property, an application should attach a handler to the PropertyChanged event to be informed when the user selects a new time.

For information about setting font properties, see Fonts. It's possible to use an unconstrained horizontal layout option such as CenterStartor End with TimePicker :. However, this is not recommended. Depending on the setting of the Format property, selected times might require different display widths.

For example, the "T" format string causes the TimePicker view to display times in a long format, and " AM" requires a greater display width than the short time format "t" of " AM". Depending on the platform, this difference might cause the TimePicker view to change width in layout, or for the display to be truncated. The TimePicker can be used to select a time, and when that time occurs an alert dialog is displayed that reminds the user of the text in the Entryprovided the Switch is toggled on.

Here's the XAML file:. The Entry lets you enter reminder text that will be displayed when the selected time occurs. The TimePicker is assigned a Format property of "T" for long time format. It has an event handler attached to the PropertyChanged event, and the Switch has a handler attached to its Toggled event.

These events handlers are in the code-behind file and call the SetTriggerTime method:. Today property value and the TimeSpan value returned from the TimePicker. This is necessary because the DateTime. Today property returns a DateTime indicating the current date, but with a time of midnight. If the timer time has already passed today, then it's assumed to be tomorrow.In our Xamarin. Forms, picker control has multi column support.

By using this, you we can populate day, month, year, hour, and minute values of collection in picker control. This class should be inherited from picker control. Date collection is the main collection, and this collection has been assigned to ItemsSource of picker control. Step 3 : Update the day value based on month and year values by using Selection changed event of picker control.

Since the days of each month differs, you should handle this collection. The following code demonstrates how to define header for each column of picker control.

The DatePicker allows users to select the year, month, and day in a consistent interface across devices and applications.

This will allow an application to display the DatePicker as a popup dialog or embedded in an Activity. In addition, the DialogFragment will manage the lifecycle and display of the dialog, reducing the amount of code that must be implemented. The sample application will display the DatePickerDialog as a modal dialog when the user clicks a button on an Activity.

When the date is set by the user, a TextView will update with the date that was selected. The sample application for this guide targets Android 4. It is possible to support older versions of Android with the addition of the Android Support Library v4 to the project and some code changes. This sample will extend DialogFragment.

The subclass will host and display a DatePickerDialog :. This interface is implemented by the hosting DialogFragment. If the user clicks the Cancel button, then fragment and dialog will dismiss themselves. There are several ways the DialogFragment can return the selected date to the hosting activity:. Invoke a method or set a property — The Activity can provide a property or method specifically for setting this value. When the fragment is to be displayed, Android will call the method OnCreateDialog.

This method will create a new DatePickerDialog object and initialize it with the current date and the callback object which is the current instance of the DatePickerFragment. OnDateSet is invoked is in the range of 0 to 11, and not 1 to The day of the month will be in the range of 1 to 31 depending on which month was selected. Now that the DialogFragment has been implemented, this section will examine how to use the fragment in an Activity. In the sample app that accompanies this guide, the Activity will instantiate the DialogFragment using the NewInstance factory method and then display it invoke DialogFragment.

This sample discussed how to display a DatePicker widget as a popup modal dialog as a part of an Android Activity. This sample also demonstrated how the DialogFragment may interact with the host Activity to display the selected date.

The example below creates a working DatePicker that displays the current date and allows the user to select a date between the specified ranges. The value for the Date property is specified with the x:Static markup extension, and the MinimumDate and MaximumDate properties are specified by calling the Parse method with the x:FactoryMethod and x:Arguments tags.

The example below requires a namespace declaration in the root ContentPage or ContentView tags. Backing store for the FontAttributes property. Backing store for the FontFamily property. Backing store for the FontSize property. Backing store for the TextColor property. Gets or sets the X component of the center point for any transform, relative to the bounds of the element.

This is a bindable property. Gets or sets the Y component of the center point for any transform, relative to the bounds of the element. Gets or sets a value that allows the automation framework to find and interact with this element. Gets or sets the color which will fill the background of a VisualElement. Gets or sets object that contains the properties that will be targeted by the bound properties that belong to this BindableObject.

Gets a value that indicates whether the font for the date picker text is bold, italic, or neither. Gets or sets the LayoutOptions that define how the element gets laid in a layout cycle. Gets or sets a value indicating whether this element should be involved in the user interaction cycle. Gets or sets a value indicating whether this element is enabled in the user interface.

Gets or sets a value that indicates whether this element is included in tab navigation. Gets or sets a value that determines whether this elements should be part of the visual tree or not. Gets or sets the opacity value applied to the element when it is rendered.

Gets the element which is the closest ancestor of this element that is a VisualElement. Apply the bindings to BindingContext. Signals the end of a batch of commands to the element and that those commands should now be committed.To provide a way for the user to select a time, you can use TimePicker.

Android apps typically use TimePicker with TimePickerDialog for selecting a time value — this helps to ensure a consistent interface across devices and applications. TimePickerDialog is a helper class that encapsulates the TimePicker in a dialog. This makes it possible for an application to display the TimePicker as a popup dialog or embed it in an Activity. In addition, the DialogFragment manages the lifecycle and display of the dialog, reducing the amount of code that must be implemented.

Xamarin.Forms TimePicker

The sample application displays the TimePickerDialog as a modal dialog when the user clicks a button on an Activity. When the time is set by the user, the dialog exits and a handler updates a TextView on the Activity screen with the time that was selected.

The sample application for this guide targets Android 4. It is possible to support older versions of Android with the addition of the Android Support Library v4 to the project and some code changes. Clicking the Cancel button causes the fragment and dialog to be dismissed.

DialogFragment returns the selected time to the hosting Activity in one of three ways:. Invoking a method or setting a property — The Activity can provide a property or method specifically for setting this value.

Android projects, see Hello, Android to learn how to create a new project. Note that this layout uses hard-coded strings and dimensions to make the app simpler and easier to understand — a production app normally uses resources for these values as can be seen in the DatePicker code example. When you build and run this example, you should see an initial screen similar to the following screen shot:.

The next step is to create this DialogFragment. Add the following class to MainActivity. This TimePickerFragment class is broken down into smaller pieces and explained in the next section. TimePickerFragment is a subclass of DialogFragment.

Xamarin Android Tutorial - Date Dialog Picker

It also implements the TimePickerDialog. The timeSelectedHandler Action is initialized to an empty delegate to prevent null reference exceptions:. This method creates a new TimePickerDialog object and initializes it with the Activity, the callback object which is the current instance of the TimePickerFragmentand the current time:. OnTimeSet creates a DateTime object using the current date and merges in the time hour and minute selected by the user:. OnTimeSet invokes this handler to update the Activity's time display to the selected time this handler is implemented in the next section :.

Now that the DialogFragment has been implemented, it is time to instantiate the DialogFragment using the NewInstance factory method and display it by invoking DialogFragment. Show :. After TimeSelectOnClick instantiates a TimePickerFragmentit creates and passes in a delegate for an anonymous method that updates the Activity's time display with the passed-in time value.

Finally, it launches the TimePicker dialog fragment via DialogFragment. Show to display the TimePicker to the user. Build and run the app. Next, add the following line of code to OnCreateDialog immediately after is24HourFormat is declared and initialized:.

This change forces the flag passed to the TimePickerDialog constructor to be true so that hour mode is used instead of the time format of the hosting Activity. Because the handler calls DateTime.Download the sample. The Xamarin. Forms DatePicker invokes the platform's date-picker control and allows the user to select a date. DatePicker defines eight properties:. The DatePicker fires a DateSelected event when the user selects a date. Otherwise, DatePicker will raise an exception.

All eight properties are backed by BindableProperty objects, which means that they can be styled, and the properties can be targets of data bindings. The Date property has a default binding mode of BindingMode.

Parse method with a CultureInfo. InvariantCulture argument to convert the string to a DateTime value. The dates must be specified in a precise format: two-digit months, two-digit days, and four-digit years separated by slashes:.

In this example, all three properties are initialized to the corresponding properties in the viewmodel. Because the Date property has a binding mode of TwoWayany new date that the user selects is automatically reflected in the viewmodel. If the DatePicker does not contain a binding on its Date property, an application should attach a handler to the DateSelected event to be informed when the user selects a new date.

For information about setting font properties, see Fonts. It's possible to use an unconstrained horizontal layout option such as CenterStartor End with DatePicker :. However, this is not recommended. Depending on the setting of the Format property, selected dates might require different display widths.

For example, the "D" format string causes DateTime to display dates in a long format, and "Wednesday, September 12, " requires a greater display width than "Friday, May 4, ". Depending on the platform, this difference might cause the DateTime view to change width in layout, or for the display to be truncated. These can be used to select two dates, and the program calculates the number of days between those dates.

The program doesn't change the settings of the MinimumDate and MaximumDate properties, so the two dates must be between and Each DatePicker is assigned a Format property of "D" for a long date format.

Notice also that the endDatePicker object has a binding that targets its MinimumDate property. The binding source is the selected Date property of the startDatePicker object. This ensures that the end date is always later than or equal to the start date. In addition to the two DatePicker objects, a Switch is labeled "Include both days in total". The two DatePicker views have handlers attached to the DateSelected event, and the Switch has a handler attached to its Toggled event.

These event handlers are in the code-behind file and trigger a new calculation of the days between the two dates:. When the sample is first run, both DatePicker views are initialized to today's date. The following screenshot shows the program running on iOS and Android:. Tapping either of the DatePicker displays invokes the platform date picker.

The platforms implement this date picker in very different ways, but each approach is familiar to users of that platform:.

This allows, for example, additional buttons to be added to the dialog. You may also leave feedback directly on GitHub.
