Web Components Date Picker Component Overview
The Ignite UI for Web Components Date Picker is a feature rich component used for entering a date through manual text input or choosing date values from a calendar dialog that pops up. Lightweight and simple to use, the Date Picker lets users navigate to a desired date with several view options – month, year, and decade. It also supports common validation properties such as minimum and maximum date constraints and required fields.
The Ignite UI for Web Components Date Picker Component lets users pick a single date through a month-view calendar dropdown or editable input field. The Web Components Date Picker also supports a dialog mode for selection from the calendar only, locale-aware and customizable date formatting and validation integration.
[!NOTE] The
IgcDatePickerComponent
is a brand new component from Ignite UI for Web Components version 5.0.0. The oldIgcDatePickerComponent
prior to this version has been renamed toXDatePicker
and its respective documentation page can be found under "Deprecated Components"
Web Components Date Picker Example
Below you can see a sample that demonstrates how the Date Picker works when users are enabled to pick a date through a manual text input and click on the calendar icon on the left to navigate to it. See how to render it.
Getting Started with Web Components Date Picker
First, you need to install the Ignite UI for Web Components by running the following command:
npm install igniteui-webcomponents
You will then need to import the IgcDatePickerComponent
, its necessary CSS, and register its module, like so:
import { defineComponents, IgcDatePickerComponent } from 'igniteui-webcomponents';
import 'igniteui-webcomponents/themes/light/bootstrap.css';
defineComponents(IgcDatePickerComponent);
For a complete introduction to the Ignite UI for Web Components, read the Getting Started topic.
Using the Web Components Date Picker Component
Display Date Picker
To instantiate a IgcDatePickerComponent
in its default dropdown
state, use the following code:
<igc-date-picker>
<p slot="helper-text">Date</p>
</igc-date-picker>
Options
The IgcDatePickerComponent
can be bound to a date
or a string
.
const DatePicker = document.querySelector('igc-date-picker') as IgcDatePickerComponent;
const date = new Date();
DatePicker.value = date;
If a string is bound to the picker, it needs to be in the ISO 8601 format:
<igc-date-picker value="2000-01-01"></igc-date-picker>
Projecting components
With prefix and suffix slots we can add different content before and after the main content of the Input.
<igc-date-picker id="DatePicker">
<igc-icon slot="suffix" name="arrow_upward" collection="material" class="small" onclick="DatePicker.stepUp()"></igc-icon>
</igc-date-picker>
The above snippet will add an additional icon at the end of the input, right after the default clear icon. This will not remove the default toggle icon, though as prefixes and suffixes can be stacked one after the other.
Customizing the toggle and clear icons
The calendar and clear icon could be templated by using the calendar
and clear
slots:
<igc-date-picker id="DatePicker">
<igc-icon slot="calendar" name="calendar" collection="material" class="small"></igc-icon>
<igc-icon slot="clear" name="delete" collection="material" class="small"></igc-icon>
</igc-date-picker>
Custom action buttons
The picker's action buttons can be templated using the actions
slot:
<igc-date-picker id="DatePicker">
<igc-button slot="actions" onclick="DatePicker.showWeekNumbers = true">Show Week Numbers</igc-button>
</igc-date-picker>
Keyboard Navigation
The IgcDatePickerComponent
has intuitive keyboard navigation that makes it easy to increment, decrement, or jump through different DateParts among others without having to touch the mouse.
Keys | Description |
---|---|
← | Move one character to the beginning |
→ | Move one character to the end |
Home | Move to the beginning |
End | Move to the end |
Ctrl / Command + ← | Move to the beginning of the date/time section - current one or left one |
Ctrl / Command + → | Move to the end of the date/time section - current on or right one |
Focus on a date/time part + ↓ | Decrements a date/time part |
Focus on a date/time part + ↑ | Increments a date/time part |
Ctrl / Command + ; | Sets the current date/time as the value of the editor |
Esc | Closes the calendar pop-up and focuses the input field |
Examples
Dialog Mode
The IgcDatePickerComponent
also supports a dialog
mode:
<igc-date-picker id="DatePicker" mode="dialog">
</igc-date-picker>
Display and input format
inputFormat
and displayFormat
are properties which can be set to make the picker's editor follow a specified format. The inputFormat
is locale based, so if none is provided, the picker will default to the one used by the browser.
A good thing to note is that the Date Picker Component will always add a leading zero on the date
and month
portions if they were provided in a format that does not have it, e.g. d/M/yy
becomes dd/MM/yy
. This applies only during editing.
displayFormat
is used to format the picker's input when it is not focused. If no displayFormat
is provided, the picker will use the inputFormat
as its displayFormat
.
More information about these can be found in the IgcDateTimeInputComponent
format section.
Increment and decrement
The IgcDatePickerComponent
exposes stepUp
and stepDown
methods. Both of which come from the IgcDateTimeInputComponent
and can be used for incrementing and decrementing a specific DatePart
of the currently set date.
<igc-date-picker id="DatePicker">
<igc-icon slot="prefix" name="arrow_upward" collection="material" onclick="DatePicker.stepUp()"></igc-icon>
<igc-icon slot="suffix" name="arrow_downward" collection="material" onclick="DatePicker.stepDown()"></igc-icon>
</igc-date-picker>
In Forms
The IgcDatePickerComponent
could be used in a form element, the component's min
and max
properties act as form validators.
In forms, we can handle the igcChange
event of the component and update the value of the label.
Calendar Specific settings
The IgcDatePickerComponent
can modify some of the calendar's settings via the properties that the Date Picker exposes. Some of these include visibleMonths
which allows more than one calendar to be displayed when the picker expands, weekStart
which determines the starting day of the week, showWeekNumbers
which shows the number for each week in the year and more.
Internationalization
The localization of the IgcDatePickerComponent
can be controlled through its locale
input.
Here is how a IgcDatePickerComponent
with Japanese locale definition would look like:
<igc-date-picker locale="ja-JP">
</igc-date-picker>
Styling
The IgcDatePickerComponent
component derives from the IgcInputComponent
and IgcCalendarComponent
component, so it exposes all available CSS parts. See Input Styling and Calendar Styling for reference.

background-color: var(--ig-primary-500);
