  Or maybe easier in App.xaml:

  <Application x:Class="ObservoForm.Client.Win.App" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="using:ObservoForm.Client.Win" RequestedTheme="Light"> <Application.Resources> <ResourceDictionary> <Style TargetType="TimePicker"> <Setter Property="MinWidth" Value="0" /> </Style> <Style TargetType="DatePicker"> <Setter Property="MinWidth" Value="0" /> </Style> </ResourceDictionary> </Application.Resources> </Application>

  It works but I have an issue on the dateChange event (DatePicker). The date of the Xamarin.Forms.Datepicker don't change and the entry of the datepicker become empty.

  Bind the Xamarin.Forms.Datepicker works now.

  • DatePickerRenderer

  
  protected override void OnElementChanged(ElementChangedEventArgs e)
          {
              base.OnElementChanged(e);
  
              if (e.NewElement != null)
              {
                  SetNativeControl(new Windows.UI.Xaml.Controls.DatePicker { MinWidth = 0 });
                  this.Control.DateChanged += dateChanged;     
              }
          }
  
  private void dateChanged(object sender, DatePickerValueChangedEventArgs e)
          {
              this.Element.Date = e.NewDate.Date;
          }
  
  

  However I don't know how to correctly bind the datepicker entry.

  I had an exception when doing the XAML version: Message "Position 14:37. Can't resolve MinWidthProperty on DatePicker". Can you help please? I did this inside a Grid:
  <Grid.Resources> <ResourceDictionary> <Style TargetType="DatePicker"> <Setter Property="MinWidth" Value="0" /> </Style> </ResourceDictionary> </Grid.Resources>

  @joao.martins : Are you writing this code into the PCL project? If yes, it won't work. You have to write the XAML code directly in the App.xaml from the Windows UWP project.
  We define here the UI from the Windows.UI.Xaml.Controls.DatePicker control and not the Xamarin.Forms.DatePicker.

  @Thibault_Vellicus I am facing the same problem. If I write the suggested code in the UWP app.xaml file then it is working fine. But it is not working through the one using CustomRenderer.

  Here is the snippet of my custom date picker renderer:
  _[assembly: ExportRenderer(typeof(CustomDatePicker), typeof(CustomDatePickerRenderer))]
  namespace MyApp.UWP.Implementations.Controls
  {
  public class CustomDatePickerRenderer : DatePickerRenderer
  {
  protected override void OnElementChanged(ElementChangedEventArgs e)
  {
  base.OnElementChanged(e);

          if (Control != null)
          {
              Control.Background = new SolidColorBrush(Colors.Transparent);
              Control.FocusVisualPrimaryBrush = new SolidColorBrush(Colors.Transparent);
              Control.FocusVisualSecondaryBrush = new SolidColorBrush(Colors.Transparent);
              Control.BorderThickness = new Windows.UI.Xaml.Thickness(0);
              Control.FontSize = 16;
      Control.MinWidth = 0;
          }
      }
  }
  

  }_

  I am trying to set the min-width of the control to 0 but it doesn't seem to affect the date picker at all. Could you please suggest something as I would like to resolve this issue using the renderer.

  Thanks in advance!
