Blazor Date Picker Component Overview
The Blazor Date Picker component allows the user to choose a date from a visual Gregorian calendar or type it into a date input that can accept only dates. You can control the date format of the input, how the user navigates through the calendar, and which dates the user cannot select.
The Date Picker component is part of Telerik UI for Blazor, a
professional grade UI library with 90+ native components for building modern and feature-rich applications. To try it out sign up for a free 30-day trial.
To use a Telerik Date Picker for Blazor, add the TelerikDatePicker tag.
Basic date picker with namespace and reference
The selected date is: @datePickerValue.ToShortDateString()
<br />
<TelerikDatePicker @bind-Value="datePickerValue" @ref="theDatePicker"></TelerikDatePicker>
@code {
DateTime datePickerValue { get; set; } = DateTime.Now;
Telerik.Blazor.Components.TelerikDatePicker<DateTime> theDatePicker;
// the type of the component depends on the type of the value
// in this case it is DateTime, but it could be DateTime?
}

ThePlaceholderwill appear if the component is bound to nullable DateTime object -DateTime?, but will not be rendered if the component is bound to the default value of a non-nullable DateTime object. The Placeholder value will be displayed when the input is not focused. Once the user focuses it to start typing, the Format Placeholder (default or customized one) will override the Placeholder to indicate the format the date should be entered in.Validation - see the Input Validation article.
ValidateOn- configures the event that will trigger validation (if validation is enabled). Read more at Validation Modes for Simple Inputs.
The date picker is, essentially, a date input and a calendar and the properties it exposes are mapped to the corresponding properties of these two components. You can read more about their behavior in the respective components' documentation.
