DatePicker shows red border when the selected date is cleared

[Domingos Portela]

I have a DatePicker and a DateInput bound to the same nullable DateTime property (for behavior testing purposes).

<TelerikDateInput @bind-Value="@TestDate" />
<TelerikDatePicker @bind-Value="@TestDate" />

public DateTime? TestDate { get; set; } = null;

As it isn't a required field, the user can fill in the field and delete it afterwards (by selecting the full date and pressing the "Del" key). When this happens, the DateInput, in terms of layout behaves as if it has never been filled. On the other hand, the DatePicker shows a red border as if it was a required field that has yet to be filled in.

Is there any way to not show the red border when the DatePicker is cleared?

Hello Domingos Portela,

We have an open bug report that describes the issue you are facing - DatePicker should accept null value as valid when bound to nullable DateTime. I have added your Vote for it and you can click the Follow button to receive email notifications on status updates. 

In the public post, you can find a few workarounds until the bug is fixed.
