Blazor DateTimePicker

The DateTimePicker has validation modes that allow you to define whether to trigger validation on change, blur, or while typing, allowing you to choose the best one for a specific use case.

The Telerik UI for Blazor DateTimePicker adaptive mode enables a mobile-friendly rendering of its date and time selector popup. Simply set the AdaptiveMode parameter to AdaptiveMode.Auto and this will trigger the picker component to automatically adapt to the current screen size and will change its rendering accordingly. In auto adaptive mode, the DateTimePicker component also allows you to define the title text rendered in the header of the popup.

The DateTimePicker offers the standard ValueChanged event and also an OnChange event that still lets you react to the user choosing a new date and time but does not prevent two-way binding. The component also fires the OnBlur event which is triggered when it loses focus. 

The Telerik DateTimePicker automatically carries culture-aware formats to the client so users see the dates they are used to – for example, if you set the format to “d” people in the US can see MM/dd/yyyy while people in the UK can see dd/MM/yyyy. Days of the week and button texts are easily translatable to any language.

The Telerik DateTimePicker component honors web accessibility standards (WCAG, Section 508 and WAI-ARIA attributes for screen readers) and lets you enter values with the keyboard only – not only by typing, but also by pressing the arrow keys, which includes navigation in the calendar and time tumblers popups as well – all without ever touching the mouse.

The Telerik Blazor Scheduler has several built-in themes such as Default (our own styling), Material (based on the Material Design guidelines), Bootstrap (which looks like the Bootstrap styling to integrate better) and Fluent (based on Microsoft Fluent UI). You can easily customize any of out-of-the-box themes with a few lines of CSS, or create new theme to match your colors and branding by using the Telerik SASS ThemeBuilder application.

The Telerik Blazor DateTimePicker restricts input to the format specified by the developer. This ensures a valid date, time, and full control over the display.

You can choose from the standard .NET format specifiers or write your own—just like you would with any C# code.

Within a single dedicated tag, the DateTimePicker allows you to simply configure popups.  In addition to that, the Open and Close methods allow you to toggle the popup visibility without triggering the OnOpen/OnClose events.

To give you more flexibility while editing the day, year, month, date and time values, the Telerik UI for Blazor DateTimePicker component is equipped with two auto-tabbing properties called AutoSwitchParts and AutoSwitchKeys. Users can also copy and paste a specific date and time format into the component without any need for manual typing.

Additional properties you can benefit from include:

The Telerik UI for Blazor DateTimePicker component supports right-to-left configuration. The RTL functionality is supported by most of our components to accommodate users who communicate in a right-to-left language script, such as Arabic and Hebrew.

The Blazor DateTimePicker component allows users of your application to input dates and times conforming to the specified validation requirements, format, culture, min and max settings. The DateTimePicker works in both Blazor WebAssembly (WASM) and Server-side Blazor apps, and supports forms validation, keyboard navigation and provides events.

The user is presented with a popup they can use to navigate in a visual manner to choose the desired date (through a calendar) and time (through modern spinners).

Form validation through DataAnnotation attributes comes out of the box.

The component, just like all other Telerik UI for Blazor input components, supports keyboard navigation to switch between components thanks to the HTML TabIndex property. Pressing Tab will normally focus the next available input component, the same way your users are accustomed to when standard HTML inputs are used. Having the TabIndex setting lets you customize that order.

With the Week Number Column feature, you can easily add the corresponding week number (one through 52) to any date or date range.
