# Date Picker Dialog Box (DatePickerDialog) A date picker dialog box is a dialog box that allows users to select a date from the given range. > **NOTE** > > - The APIs of this module are supported since API version 8. Updates will be marked with a superscript to indicate their earliest API version. > > - The functionality of this module depends on UI context. This means that the APIs of this module cannot be used where [the UI context is unclear](../../../ui/arkts-global-interface.md). For details, see [UIContext](../arkts-apis-uicontext-uicontext.md). ## DatePickerDialog ### show(deprecated) static show(options?: DatePickerDialogOptions) Shows a date picker dialog box. > **NOTE** > > This API is deprecated since API version 18. You are advised to use [showDatePickerDialog](../arkts-apis-uicontext-uicontext.md#showdatepickerdialog) in [UIContext](../arkts-apis-uicontext-uicontext.md) instead. > > Since API version 10, you can use the [showDatePickerDialog](../arkts-apis-uicontext-uicontext.md#showdatepickerdialog) API in [UIContext](../arkts-apis-uicontext-uicontext.md), which ensures that the date picker dialog box is shown in the intended UI instance. **Atomic service API**: This API can be used in atomic services since API version 11. **System capability**: SystemCapability.ArkUI.ArkUI.Full **Device behavior differences**: On wearables, calling this API results in a runtime exception indicating that the API is undefined.

In this way, when the date picker dialog box is displayed again, the selected date is the date last confirmed. this.selectedDate = value; console.info("DatePickerDialog:onDateAccept()" + value.toString()); }, onCancel: () => { console.info("DatePickerDialog:onCancel()"); }, onDateChange: (value: Date) => { console.info("DatePickerDialog:onDateChange()" + value.toString()); }, onDidAppear: () => { console.info("DatePickerDialog:onDidAppear()"); }, onDidDisappear: () => { console.info("DatePickerDialog:onDidDisappear()"); }, onWillAppear: () => { console.info("DatePickerDialog:onWillAppear()"); }, onWillDisappear: () => { console.info("DatePickerDialog:onWillDisappear()"); } }) }) }.width('100%') } } ``` ![DataPickerDialog](figures/DatePickerDialog.gif) ### Example 2: Customizing the Style In this example, **disappearTextStyle**, **textStyle**, **selectedTextStyle**, **acceptButtonStyle**, and **cancelButtonStyle** are configured to customize the text and button style. ```ts // xxx.ets @Entry @Component struct DatePickerDialogExample { selectedDate: Date = new Date("2010-1-1"); build() { Column() { Button("DatePickerDialog") .margin(20) .onClick(() => { this.getUIContext().showDatePickerDialog({ start: new Date("2000-1-1"), end: new Date("2100-12-31"), selected: this.selectedDate, disappearTextStyle: { color: '#297bec', font: { size: '20fp', weight: FontWeight.Bold } }, textStyle: { color: Color.Black, font: { size: '18fp', weight: FontWeight.Normal } }, selectedTextStyle: { color: Color.Blue, font: { size: '26fp', weight: FontWeight.Regular } }, acceptButtonStyle: { type: ButtonType.Normal, style: ButtonStyleMode.NORMAL, role: ButtonRole.NORMAL, fontColor: 'rgb(81, 81, 216)', fontSize: '26fp', fontWeight: FontWeight.Bolder, fontStyle: FontStyle.Normal, fontFamily: 'sans-serif', backgroundColor: '#A6ACAF', borderRadius: 20 }, cancelButtonStyle: { type: ButtonType.Normal, style: ButtonStyleMode.NORMAL, role: ButtonRole.NORMAL, fontColor: Color.Blue, fontSize: '16fp', fontWeight: FontWeight.Normal, fontStyle: FontStyle.Italic, fontFamily: 'sans-serif', backgroundColor: '#50182431', borderRadius: 10 }, onDateAccept: (value: Date) => { // Use the setFullYear method to set the date when the OK button is touched.

In this way, when the date picker dialog box is displayed again, the selected date is the date last confirmed. this.selectedDate = value; console.info("DatePickerDialog:onDateAccept()" + value.toString()); } }); }) }.width('100%') } } ``` ### Example 9: Setting Cyclic Scrolling This example demonstrates how to set whether to enable cyclic scrolling using **canLoop**. ```ts // xxx.ets @Entry @Component struct DatePickerDialogExample { @State isLoop: boolean = true; selectedDate: Date = new Date("2010-1-1"); build() { Column() { Button("DatePickerDialog") .margin(20) .onClick(() => { this.getUIContext().showDatePickerDialog({ start: new Date("2000-1-1"), end: new Date("2100-12-31"), selected: this.selectedDate, canLoop: this.isLoop, onDateAccept: (value: Date) => { // Use the setFullYear method to set the date when the OK button is touched. In this way, when the date picker dialog box is displayed again, the selected date is the date last confirmed. this.selectedDate = value; console.info("DatePickerDialog:onDateAccept()" + value.toString()); } }); }) Row() { Text('Cyclic scrolling').fontSize(20) Toggle({ type: ToggleType.Switch, isOn: true }) .onChange((isOn: boolean) => { this.isLoop = isOn; }) }.position({ x: '60%', y: '40%' }) }.width('100%') } } ``` ### Example 10: Customizing the Background Blur Effect This example demonstrates how to customize the background blur effect by configuring [backgroundBlurStyleOptions](#datepickerdialogoptions). This functionality is supported since API version 19. ```ts @Entry @Component struct DatePickerDialogExample { selectedDate: Date = new Date("2010-1-1"); build() { Stack({ alignContent: Alignment.Top }) { Image($r('app.media.bg')) Column() { Button("DatePickerDialog") .margin(20) .onClick(() => { this.getUIContext().showDatePickerDialog({ start: new Date("2000-1-1"), end: new Date("2100-12-31"), selected: this.selectedDate, backgroundColor: undefined, backgroundBlurStyle: BlurStyle.Thin, backgroundBlurStyleOptions: { colorMode: ThemeColorMode.LIGHT, adaptiveColor: AdaptiveColor.AVERAGE, scale: 1, blurOptions: { grayscale: [20, 20] }, }, }); }) }.width('100%') } } } ``` ### Example 11: Customizing the Background Effect This example demonstrates how to customize the background effect by configuring [backgroundEffect](#datepickerdialogoptions). This functionality is supported since API version 19. ```ts @Entry @Component struct DatePickerDialogExample { selectedDate: Date = new Date("2010-1-1"); build() { Stack({ alignContent: Alignment.Top }) { Image($r('app.media.bg')) Column() { Button("DatePickerDialog") .margin(20) .onClick(() => { this.getUIContext().showDatePickerDialog({ start: new Date("2000-1-1"), end: new Date("2100-12-31"), selected: this.selectedDate, backgroundColor: undefined, backgroundBlurStyle: BlurStyle.Thin, backgroundEffect: { radius: 60, saturation: 0, brightness: 1, color: Color.White, blurOptions: { grayscale: [20, 20] } }, }); }) }.width('100%') } } } ```
