Datepicker Blazor

I use this code to genereate the datepicker: <RadzenDatePicker TValue="DateTime?" ShowTime="true" Change="@(args => Change(args, "DatePicker with 12 hour time format", "MM/dd/yyyy h:mm tt"))" HourFormat="12" DateFormat="MM/dd/yyyy h:mm tt" />

But i cant open the datepicker and when i press the symbol on right side. i get an error messenger event:1 Uncaught ReferenceError: Radzen is not defined
at HTMLButtonElement.onclick (event:1) and this is the code that it could not run Radzen.togglePopup(this.parentNode, 'popupTD11CY4UEE') . Any ideas?

You’ve not added the required JavaScript:

Oh sorry have put the line on the wrong places sorry, no to my next problem :stuck_out_tongue: I have done this and now i can open the datepicker from the symbol but not pick a date. i dont get any wrong messenger. Any idea? Nothing happend when i press a date. I think my project cant read the css style from Radzen
