Answer 1

You can use a UITextField and add date picker as a Input vie. And set PlaceHolder as "Date" or any string you want.
Sample Code
UITextField TextInput = new UITextField();
TextInput.Frame = new CGRect(40, 280, View.Frame.Width - 80, 40);
TextInput.Placeholder = "Date";
var picker = new UIDatePicker();
TextInput.InputView = picker;

Here is an example how to do it in ViewCell. You can use similar idea with View
public class TimePickerInCellPage : ContentPage
{
private ListView _listView;
public TimePickerInCellPage()
{
_listView = new ListView
{
RowHeight = 80,
SeparatorColor = Color.Blue,
SeparatorVisibility = SeparatorVisibility.Default
};
_listView.ItemsSource = new List<TaskTime>() {
new TaskTime { Id=1, StartTime=TimeSpan.FromHours(3) } ,
new TaskTime { Id=1, StartTime=TimeSpan.FromHours(5) } ,
new TaskTime { Id=1, StartTime=TimeSpan.FromHours(7) } ,
};
_listView.ItemTemplate = new DataTemplate(typeof(MyCell));
Content = new StackLayout
{
VerticalOptions = LayoutOptions.FillAndExpand,
Children = { _listView }
};
}
}
public class TaskTime
{
public int Id { get; set; }
public string Task { get; set; }
public TimeSpan StartTime { get; set; }
}
class MyCell : ViewCell
{
private readonly DatePicker _myTimePicker;
//private readonly TimePicker _myTimePicker;
public MyCell()
{
//_myTimePicker = new TimePicker()
_myTimePicker = new DatePicker()
{
HorizontalOptions = LayoutOptions.EndAndExpand
};
//_myTimePicker.Format = "HH:mm:ss";
_myTimePicker.Format = "dd:MM:yy HH:mm:ss";
_myTimePicker.SetBinding(TimePicker.TimeProperty, "StartTime");
_myTimePicker.PropertyChanged += MyTimePicker_PropertyChanged;
//_myTimePicker.Focused += _myTimePicker_Focused;
var viewLayout = new StackLayout()
{
HorizontalOptions = LayoutOptions.StartAndExpand,
Orientation = StackOrientation.Horizontal,
Padding = new Thickness(20),
Children = { _myTimePicker }
};
View = viewLayout;
}
bool firstTimeSet; //set when initial binding happens
//private void _myTimePicker_Focused(object sender, FocusEventArgs e)
//{
// firstTimeSet=true;
//}
private void MyTimePicker_PropertyChanged(object sender, System.ComponentModel.PropertyChangedEventArgs e)
{
//if (e.PropertyName == TimePicker.TimeProperty.PropertyName)
if (e.PropertyName == DatePicker.DateProperty.PropertyName)
{
if (!firstTimeSet)
firstTimeSet = true;
else
{
int x = 0;
string s = _myTimePicker.Date.ToString("dd/MM/yy HH:mm:ss");
}
}
}
}
