datepicker bug

[Bruno]

I use the TelerikDatePicker: I enter a date and I remove it again, then I click on the calendar icon and I receive an exception...



Microsoft.AspNetCore.Components.Web.ErrorBoundary | Message: Unhandled exception rendering component: "Object reference not set to an instance of an object."
System.NullReferenceException: Object reference not set to an instance of an object.

Hello Bruno,

The occurrence of this error can be attributed to a race condition triggered by rapid, multiple UI refreshes. In this scenario, the DatePicker undergoes multiple recreations in quick succession. Consequently, the nested Calendar component is destroyed, rendering it inaccessible to the DatePicker and resulting in the observed exception.

For further information about this problem, you can check our forum, where another customer is having the same issue as you. My colleague has provided some advice and the potential reasons that could be causing the problem.
