MinValue does not support DateTime.Now

[Eimantas Baigys]

Hello, there is a bug somewhere in the datetime/date picker compoments which causes UI to freeze after you select date. After digging around I found out that cause of this is setting Min="DateTime.Now" rather than assigning it to a variable and using it in the component. 

Not sure how far back it goes but version 20.1.0.56 was working fine, as I noticed this only after upgrading from that version to latest 20.4.0.38 

Please fix this as I have few hundred components which needs updating because of this weird bug.

Working version:

<SfDatePicker @bind-Value="datepicker" Min="@MinDate" Placeholder="Select Date:" FloatLabelType="FloatLabelType.Always" />

@code {

    DateTime MinDate = DateTime.Now;

}

Not working version:

<SfDatePicker @bind-Value="datepicker" Min=DateTime.Now Placeholder="Select Date:" FloatLabelType="FloatLabelType.Always" />

Also if Date picker component has ValueChanged property set for example I would like to validate selection and then depending on a result show a dialog - UI freeze for example (again this was working in 20.1.0.56):

<SfDateTimePicker Value="Model.NewDueDate" Readonly="Model.AssignedToContractorUserId == null" ValueChanged="ValidateNewDueDate" TValue="DateTime?" Min="minNewAllocationDate" Step="15" AllowEdit=false Placeholder="Set new arrival time:" FloatLabelType="FloatLabelType.Always" />

async Task ValidateNewDueDate(DateTime? newDueDate)

    {

        if (Some conditions are true)

        {

            //This is a prerendered SfDialog Compoment and a model simply represends data it should render on open. It also has a callbacks on button clicks

            await ShowConfirmationDialog(new ConfirmationDialogModel()

            {

                .............

            });

        }

        else

        {

            Model.NewDueDate = newDueDate;

            StateHasChanged();

        }

    }
