Datepicker invalid cast

Radzen.Blazor Components
1

I am trying to use RadzenDatePicker inside a RadzenDataGridColumn. When I select a date I get the following error message:
Microsoft.AspNetCore.Components.WebAssembly.Rendering.WebAssemblyRenderer[100] Unhandled exception rendering component: Specified cast is not valid.

I am using a DateOnly property.
This is the code

<RadzenDataGridColumn TItem="SubscriptionResponse" Property="Name" Title="Name" Width="100px" Frozen="true">
                <EditTemplate Context="subscriptionResponse">
                    <RadzenTextBox @bind-Value="subscriptionResponse.Name" Style="width:200px; display: block" Name="SubscriptionName"/>
                </EditTemplate>
            </RadzenDataGridColumn>
            <RadzenDataGridColumn TItem="SubscriptionResponse" Property="StartDate" Title="Start Date" Width="160px">
                <Template Context="subscriptionResponse">
                    @subscriptionResponse.StartDate
                </Template>
                <EditTemplate Context="subscriptionResponse">
                    <RadzenDatePicker
                        @bind-Value="subscriptionResponse.StartDate"
                        Style="width: 100%">
                    </RadzenDatePicker>
                </EditTemplate>
            </RadzenDataGridColumn>

Found this - Forum answer

There is no support for the DateOnly type. I converted the object to DateTime.
