How do I set the default date

Hi,

If a date field has no value and the user enters it the date picker shows but defaults to year one. How do I get it to default to today with out using minimum date?

Thanks
Richard

Hi Richard,  
  
We have checked your requirement for displaying current date time (today) without setting value to the DatePicker. In SfDataForm, DateTime will be displayed based on the value given in DateTime property type or based on the selected date in the date picker header.  
You can set null value to DateTime (instead of DateTime default value) such that current date will be displayed in the date picker.  
  
Code snippet  
  
  
  private DateTime? displayDate;  
       
        public DateTime? DisplayDate  
        {  
            get { return displayDate; }  
            set { displayDate = value; }  
        }  
  
  
Sample:  DatePickerSample
  
Please let us know provided solution meets your requirement.

Hi,

If I use the below in a data model tied to SQLLite

 public DateTime? SomeDate { get; set; }

The date picker in Android is still set to 01/01/01 when it pops up.

Thanks 
Richard

Hi Richard,  
  
We have checked your requirement for displaying current date time (today) without setting value to the DatePicker with SQLite in sample level for Xamarin Forms Android. We are not able to reproduce the issue from our side. We have set null value to DateTime (instead of DateTime default value) as mentioned by you and current date is displayed in the date picker as expected.  
  
   public int ID { get; set; }  
   public string Name { get; set; }  
   public DateTime? SomeDate { get; set; }  
  
  ViewModel = new ViewModel();  
  dataForm.DataObject = ViewModel.OrderItemCollection[0];  
  
    public class ViewModel  
    {  
        SQLiteConnection database;  
        ObservableCollection<OrderItem> orderItemCollection;  
        ObservableCollection<OrderItem> OrderList;  
        public ObservableCollection<OrderItem> OrderItemCollection  
        {  
            get  
            {  
                if (orderItemCollection == null)  
                {  
                    GetItems();  
                    orderItemCollection = OrderList;  
                }  
                return orderItemCollection;  
            }  
        }  
         
        public ViewModel()  
        {  
  
            database = DependencyService.Get<ISQLite>().GetConnection();  
            // Create the table  
            database.CreateTable<OrderItem>();  
            database.Query<OrderItem>("INSERT INTO OrderItem (ID,Name,SomeDate)values (1002,'Blake',null)");  
            database.Query<OrderItem>("INSERT INTO OrderItem (ID,Name,SomeDate)values (1003,'Catherine',null)");  
            database.Query<OrderItem>("INSERT INTO OrderItem (ID,Name,SomeDate)values (1004,'Jude',null)");  
        }  
  
        public async void GetItems()  
        {  
            // Changing the database table items as ObservableCollection  
            var table = (from i in database.Table<OrderItem>() select i);  
  
            OrderList = new ObservableCollection<OrderItem>();  
  
            foreach (var order in table)  
            {  
                OrderList.Add(new OrderItem()  
                {  
                    ID = order.ID,  
                    Name = order.Name  
                });  
            }  
            await Task.Delay(2000);  
             
        }  
    }

I have finally had a chance to revisit this issue and it is working as you described (I could have sworn it wasn't earlier).

Hey, I'm having a similar issue, but on iOS. In Android it works ok, suggesting today's date, but on iOS, the default date when null is 01/01/0001.

Another issue I'm having is that using SfDataForm inside an SfTabView as the third tab, whenever I try to edit a field, the selected tab goes back to the first. This problem happens only in Android (Motorola Z2 Force - 8.0.0)

I'm using latest version as today: 16.4.0.52

Thanks for contacting Syncfusion Support.

2.       Including SfDataForm inside an SfTabView as the third tab, and when try to edit a field, the selected tab goes back to the first in Xamarin Forms Android. 
 
 We will analyze and update you the complete details in two business days (Feb 11th,2019). We appreciate your patience until then.
