Disabling Text Input and Opening Calendar Popup on Input Click for DatePicker in Blazor

Environment

Product
Telerik UI for Blazor

Description

I want to disable the text input so that users can only enter dates through the calendar and not by typing in the text box. Additionally, I need the calendar to open when clicking anywhere on the text box, not just the calendar icon.

This KB article also answers the following questions:

• How can I disable typing in the Telerik DatePicker component?
• How do I open the DatePicker calendar by clicking on the textbox area?
• Is it possible to prevent text input in the DatePicker and still use the calendar for date selection?

Solution

To disable text input in the DatePicker and ensure the calendar opens by clicking on the textbox area, follow these steps:

1. Disable pointer events on the DatePicker input element using CSS to prevent text input.
2. Wrap the TelerikDatePicker component in a span element and utilize its onclick event to call the Open() method of the DatePicker for opening the calendar.

@* The CSS class `.my-datepicker` is used for targeting the specific DatePicker instance.*@

<style>
    .my-datepicker input {
        pointer-events: none;
    }
</style>

<span @onclick="@OpenCalendar">
    <TelerikDatePicker @ref="@DatePickerRef"
                       Class="my-datepicker"
                       Width="294px"
                       @bind-Value="datePickerValue"
                       Format="dd MMMM yyyy"
                       Min="@Min" Max="@Max">
    </TelerikDatePicker>
</span>

@code {
    private TelerikDatePicker<DateTime> DatePickerRef { get; set; }
    private DateTime datePickerValue { get; set; } = DateTime.Now;
    private DateTime Min = new DateTime(1990, 1, 1, 8, 15, 0);
    private DateTime Max = new DateTime(2025, 1, 1, 19, 30, 45);

    private void OpenCalendar()
    {
        DatePickerRef.Open();
    }
}
