Xamarin Forms: Keyboard didn't hide - xamarin

Question

The keyboard hides when I create the page, but when I change the focus to another entry I call the same function but the soft keyboard didn't hide?
ConfigService.cs
public void HideKeyboard()
{
var inputMethodManager = Xamarin.Forms.Forms.Context.GetSystemService(Context.InputMethodService) as InputMethodManager;
if (inputMethodManager != null && Xamarin.Forms.Forms.Context is Activity)
{
var activity = Xamarin.Forms.Forms.Context as Activity;
var focusedView = activity.CurrentFocus;
var token = focusedView == null ? null : focusedView.WindowToken;
inputMethodManager.HideSoftInputFromWindow(token, HideSoftInputFlags.None);
}
}
VerplaatsingPage.xaml.cs
namespace SI_Foodware.View
{
public partial class VerplaatsingPage : ContentPage
{
VerplaatsingPageViewModel vm;
public VerplaatsingPage (SubMenu subMenu)
{
InitializeComponent ();
vm = new VerplaatsingPageViewModel(this, subMenu);
BindingContext = vm;
}
public void OnClickDestination(object o, EventArgs e)
{
}
public void OnClickSelect(object o, EventArgs e)
{
}
public void OnClickCancel(object o, EventArgs e)
{
}
protected override void OnAppearing()
{
base.OnAppearing();
ent_drager.Focus();
IConfigService configService = DependencyService.Get<IConfigService>();
configService.HideKeyboard();
}
}
}
VerplaatsingPageViewModel.cs
public void Keyboard()
{
IConfigService configService = DependencyService.Get<IConfigService>();
configService.HideKeyboard();
}
public void OnScan(string scanProperty)
{
var list = db.GetAllItems<ContainerLine>();
Artikel = list[0].ItemNo;
Description = list[0].Description;
LotNo = list[0].LotNo;
NumberOfContainer = list[0].Quantity;
KiloDrager = list[0].KgQuantity;
UnitOfMeasure = list[0].UnitofMeasureCode;
LocationFrom = list[0].BinCode;
cp.FindByName<Entry>("ent_destination").Focus();
Keyboard(); <-- Doesn't Work
}

Answer 1

I solved my problem by using
inputMethodManager.ToggleSoftInputFromWindow(token, ShowSoftInputFlags.None, HideSoftInputFlags.None);
instead of
inputMethodManager.HideSoftInputFromWindow(token, HideSoftInputFlags.None);
