Hello Rene,

You could implement the desired behavior using Validation. Our online Validation demo for the DatePicker shows how to implement a custom data annotation attribute which might be useful for your application.

Hello Rene,

The reason why this is happening is that the Min parameter is set to one day after today. When you set the Min parameter it restricts selecting any date before it. If the parameter is set to 01/10/2021 (MM/dd/yyyy) the user would not be able to click on the Today link - 01/08/2021 (MM/dd/yyyy) because the earliest date he can select is 10th of January 2021. If you tweak this example to AddDays(-1) you would be able to use the Today link. 

Code snippet:

<TelerikDatePicker @bind-Value="@datePickerValue" 
                   Min="@DateTime.Today.AddDays(-1)">
</TelerikDatePicker>

@code  {
    DateTime datePickerValue { get; set; } = DateTime.Now;
}

That being said, I am marking this as declined because this is expected behavior for the component
