Radezen Prevent Default for Delete or Backspace Keydown event

Hello
Does anyone have a Radzen code example for preventing default (cancelling) keydown on Delete or Backspace. Currently, my Radzen application crashes when a user clicks the delete or backspace in a RadzenNumeric control.

Or, if someone can tell me how to prevent the RadzenNumeric from crashing on a delete or backspace that would be great!
Thanks

Not sure why what crashed on your end - works normally on our demo:
https://blazor.radzen.com/numeric

Based on the your response, I was able to figure out what I was doing wrong. I was binding a string value to the RadzenNumeric. I changed the data type to int? and that solved the issue. Thanks for the response.
Regards,
