Null Reference Exception when choosing a time

[Jeremy]

Hi,

when following the 2-way binding example for a TimePicker control (https://blazor.syncfusion.com/documentation/timepicker/data-binding/), if I select a time value from the drop down list, a System.InvalidOperationException occurs

System.InvalidOperationException: Nullable object must have a value.

   at System.Nullable`1.get_Value()

   at Syncfusion.Blazor.Calendars.SfTimePicker`1.OnParametersSetAsync()

   at Microsoft.AspNetCore.Components.ComponentBase.CallStateHasChangedOnAsyncCompletion(Task task)

Microsoft.AspNetCore.Components.Server.Circuits.CircuitHost: Error: Unhandled exception in circuit 'mLZlx3tEfQ3hzRJu4vb-SINdZhwPtqlnY6_5GxQWNuA'.

Hi Jeremy, 

Thanks for contacting Syncfusion support. 

The reported issue is a know bug in our end and the fix will be included in upcoming patch release which is expected to be rolled out on October 6, 2020. Until then, we suggest you to use the below work-around solution “use the dummy events tag” to get rid of the reported issue.  

Once the fix included in the upcoming Nuget, you can remove the dummy events tag and check with your application with your reported issue. Please find the code snippet below for reference. 

<SfTimePicker TValue="DateTime?" @bind-Value="@DateValue"> 

    <TimePickerEvents TValue="DateTime?"></TimePickerEvents> 

</SfTimePicker> 

 

@code { 

    public DateTime? DateValue { get; set; } = new DateTime(2020, 10, 5, 10, 30, 0); 

}
