How to Troubleshoot Calendar Popup in Javascript DatePicker?

When programmatically setting a date value using the value property, the selected date displays correctly in the Javascript DatePicker input field. However, when opening the calendar popup, the calendar navigates to the current date instead of the month and year of the specified date value. This issue occurs specifically when the min and max properties are explicitly set to null.

Cause of the Issue

When the min and max properties are explicitly set to null, the calendar popup navigates to the current date rather than the date specified in the value property. This behavior differs from omitting the min and max properties entirely, where the DatePicker applies default values (January 1, 1900 for min and December 31, 2099 for max) and correctly navigates to the selected date.

Steps to Reproduce

1. Set a date value programmatically using the value property.
2. Configure the DatePicker component with min and max properties explicitly set to null.
3. Open the calendar popup.
4. Observe that the calendar navigates to the current date instead of the month and year of the specified date value.

Recommended Solution

To resolve this issue, avoid setting the min and max properties to null. Instead, explicitly define min and max values to ensure proper calendar navigation and date selection behavior. The following code demonstrates the correct implementation:

var datepicker = new ej.calendars.DatePicker({
  value: new Date(2022, 1, 2),
    min: new Date(1900, 1, 1),
    max: new Date(2099, 11, 31),
});
datepicker.appendTo('#datepicker');
