Unable to capture screen of WkWebView in Xamarin IOS

I am trying to capture the screen in IOS, Other than WkWebview all other view component I am able to capture by below code.WkWebview is giving a blank page as captured data. If I am using UIWebview the same code working Is there anything specific to do to take screen shot WkWebView.
Code for screen capture.
public static UIImage SnapshotView(this UIView view)
{
UIGraphics.BeginImageContextWithOptions(view.Bounds.Size, false, UIScreen.MainScreen.Scale);
view.DrawViewHierarchy(view.Bounds, true);
var image = UIGraphics.GetImageFromCurrentImageContext();
UIGraphics.EndImageContext();
return image;
}
WkWebView Configuration:
WKWebView _wkWebView = new WKWebView(ReaderView.Frame, new WKWebViewConfiguration());
_wkWebView.LoadFileUrl(tempUrl, tempUrl);
_wkWebView.ContentMode = UIViewContentMode.ScaleToFill;
_wkWebView.BackgroundColor = UIColor.Clear;
_wkWebView.Opaque = false;
_wkWebView.ScrollView.BackgroundColor = UIColor.Clear;
//_wkWebView.DrawViewHierarchy(_wkWebView.Bounds, true);
ReaderView.AddSubview(_wkWebView);
var imag = _wkWebView.SnapshotView();

I fixed the issue by replacing the WKWebView with PdfView.I am using this view for loading PDFs.
The latest code is below
pdfView = new PdfView();
pdfView.TranslatesAutoresizingMaskIntoConstraints = false;
ReaderView.AddSubview(pdfView);
pdfView.LeadingAnchor.ConstraintEqualTo(View.SafeAreaLayoutGuide.LeadingAnchor).Active = true;
pdfView.TrailingAnchor.ConstraintEqualTo(View.SafeAreaLayoutGuide.TrailingAnchor).Active = true;
pdfView.TopAnchor.ConstraintEqualTo(View.SafeAreaLayoutGuide.TopAnchor).Active = true;
pdfView.BottomAnchor.ConstraintEqualTo(View.SafeAreaLayoutGuide.BottomAnchor).Active = true;
// var path = Bundle.main.url(forResource: "test", withExtension: "pdf") else { return }
PdfDocument document;
// PdfDocument
using (urlString = new NSString(FilePath))
using (var tempUrl = NSUrl.CreateFileUrl(new string[] { urlString }))
document = new PdfDocument(tempUrl);
//if var document = PdfDocument(url: path) {
pdfView.Document = document;

UWP Toast works, but images (AdaptiveImage, ToastGenericHeroImage, ToastGenericAppLogo) not displaying

I am targeting Windows 10, latest OS build. I copy/pasted some stuff from the Microsoft adaptive toast examples--including the paths. Here's my code:
public void CreateToast(ToastViewModel model)
{
ToastContent content = new ToastContent()
{
Launch = "app-defined-string",
Visual = new ToastVisual()
{
BindingGeneric = new ToastBindingGeneric()
{
Children =
{
new AdaptiveText()
{
Text = "Photo Share"
},
new AdaptiveText()
{
Text = "Andrew sent you a picture"
},
new AdaptiveText()
{
Text = "See it in full size!"
},
new AdaptiveImage()
{
Source = "https://unsplash.it/360/180?image=1043"
}
},
HeroImage = new ToastGenericHeroImage()
{
Source = "https://unsplash.it/360/180?image=1043"
},
AppLogoOverride = new ToastGenericAppLogo()
{
Source = "https://unsplash.it/64?image=883",
HintCrop = ToastGenericAppLogoCrop.Circle
}
}
}
};
var toast = new ToastNotification(content.GetXml());
toast.Failed += (o, args) =>
{
var message = args.ErrorCode;
};
ToastNotificationManager.CreateToastNotifier().Show(toast);
}
The toast displays, but the images do not. Anyone have an idea?
EDIT: As #AVK suggested I decided to give it a shot using XML instead; unfortunately I get the same behavior -- toast shows, but no images. Here's my code for that (though admittedly I know even less about XML, so this code could be wrong-er):
var template = ToastTemplateType.ToastImageAndText02;
var xml = ToastNotificationManager.GetTemplateContent(template);
var elements = xml.GetElementsByTagName("text");
var text = xml.CreateTextNode(model.Title);
elements[0].AppendChild(text);
var images = xml.GetElementsByTagName("image");
var srcAttribute = xml.CreateAttribute("src");
srcAttribute.Value = "https://unsplash.it/64?image=883";
images[0].Attributes.SetNamedItem(srcAttribute);
var toast = new ToastNotification(xml);
ToastNotificationManager.CreateToastNotifier().Show(toast);

Http images are only supported in Desktop Bridge apps that have the internet capability in their manifest. Classic Win32 apps do not support http images; you must download the image to your local app data and reference it locally.

This is a Windows 10 bug that causes Toast Notification for applications to not show images.
Run the troubleshooter for Windows apps could fix it.

Windows 10 Toast Notification Visuals and Actions not working

I'm writing a c# console application that sends toast notifications in VS2017 on a Windows 10 machine. When I run my code and have only defined adaptive text content for my notification it runs correctly and displays the desired text. If I add actions, it no longer displays the adaptive text I defined ("title" and "content" below), nor does it have the option to perform said actions. If I try to add additional visuals such as a logo or picture, they do not appear but the adaptive text is unaffected.
string category = "Notifications";
string title = "New Test Notification!;
string content = "Testing push notifications!";
ToastContent toastContent = new ToastContent()
{
Visual = new ToastVisual()
{
BindingGeneric = new ToastBindingGeneric()
{
Children =
{
new AdaptiveText()
{
Text = title
},
new AdaptiveText()
{
Text = content
}
},
/*AppLogoOverride = new ToastGenericAppLogo()
{
Source = "https://unsplash.it/64?image=883",
HintCrop = ToastGenericAppLogoCrop.Circle
}*/
}
},
/*Actions = new ToastActionsCustom()
{
Buttons =
{
new ToastButton("check", "check")
{
ImageUri = "check.png"
},
new ToastButton("cancel", "cancel")
{
ImageUri = "cancel.png"
}
}
}*/
};
string toastXml = toastContent.GetContent();
XmlDocument doc = new XmlDocument();
doc.LoadXml(toastXml);
var toast = new ToastNotification(doc);
ToastNotificationManager.CreateToastNotifier(category).Show(toast);

Export payment in Applications Tab menu of Bill and Adjustments in Acumatica ERP system using webservices api

I need to export all records in Applications Tab Menu of Bill and Adjustments screen as I did in UI like this screenshot below.
I already create codes to provide it using this code below.
try
{
context.CookieContainer = new System.Net.CookieContainer();
context.Timeout = 10000000;
context.Url = url;
LoginResult login = context.Login(username, password);
AP301000Content konten = context.AP301000GetSchema();
//context.AP301000Clear();
konten.DocumentSummary.Type.Commit = false;
konten.DocumentSummary.Type.LinkedCommand = null;
var command = new Command[]
{
new Value { Value = "Bill", LinkedCommand = Konten.DocumentSummary.Type },
new Value { Value = "00123", LinkedCommand = konten.DocumentSummary.ReferenceNbr },
konten.DocumentSummary.Vendor,
konten.Applications.ReferenceNbrDisplayRefNbr,
konten.Applications.DocTypeDisplayDocType
};
var result = context.AP301000Export(command, null, 0, false, true);
}
catch (Exception x)
{
MessageBox.Show(x.Message);
}
finally
{
sCon.getLogout(context);
}
After i debug this code I got records only for VendorCD but Reference Nbr and Doc Type didn't exported. Please refer to this screenshot below.
please how to solve this issue.
Thanks

You should use "every" fields:
var command = new Command[]
{
konten.DocumentSummary.ServiceCommands.EveryDocType,
konten.DocumentSummary.ServiceCommands.EveryRefNbr,
konten.DocumentSummary.Vendor,
konten.Applications.ReferenceNbrDisplayRefNbr,
konten.Applications.DocTypeDisplayDocType
};

Keyboard quickly hides and reappears on Android using Xamarin Forms

We're trying to build a Chat App using Xamarin Forms, but we keep getting this annoying bug with the Android keyboard. Whenever the "Send" button is tapped, the focus on the Entry (text box for chatting) is lost and the keyboard disappears. That isn't what we wanted so we added this line to the TapGestureRecognizer:
messageEntry.Focus();
But for some reason, this doesn't happen fast enough, and often the keyboard goes down and immediately up again. This prevents users from quickly posting multiple message sequentially. Does anybody know how this can be fixed?

Thanks to the answer of #AdamKemp in this post, here is my solution. If the touch is within my EntryStackLayout (don't forget to create the empty custom renderer), then I don't dismiss the keyboard (which is what DispatchTouchEvent will do if CurrentFocus is EditText).
public class EditorAndButtonReproPage : ContentPage
{
public EditorAndButtonReproPage()
{
BackgroundColor = Color.Gray;
Padding = 50;
var editor = new Editor {HorizontalOptions = LayoutOptions.FillAndExpand};
var editorButton = new Button {Text = "OK", HorizontalOptions = LayoutOptions.End};
var editorLayout = new EntryStackLayout { Orientation = StackOrientation.Horizontal, Children = { editor, editorButton}, VerticalOptions = LayoutOptions.Start};
var entry = new ExtendedEntry { Placeholder = "Entry", HorizontalOptions = LayoutOptions.FillAndExpand };
var entryButton = new Button { Text = "OK", HorizontalOptions = LayoutOptions.End };
var entryLayout = new EntryStackLayout { Orientation = StackOrientation.Horizontal, Children = { entry, entryButton }, VerticalOptions = LayoutOptions.Start };
Content = new StackLayout {Children = {editorLayout, entryLayout}};
}
}
and in the MainActivity:
private bool _ignoreNewFocus;
public override bool DispatchTouchEvent(MotionEvent e)
{
var currentView = CurrentFocus;
var parent = currentView?.Parent?.Parent;
var entryStackLayout = parent as EntryStackLayout;
if (entryStackLayout != null)
{
var entryLayoutLocation = new int[2];
entryStackLayout.GetLocationOnScreen(entryLayoutLocation);
var x = e.RawX + entryStackLayout.Left - entryLayoutLocation[0];
var y = e.RawY + entryStackLayout.Top - entryLayoutLocation[1];
var entryStackLayoutRect = new Rectangle(entryStackLayout.Left, entryStackLayout.Top, entryStackLayout.Width, entryStackLayout.Height);
_ignoreNewFocus = entryStackLayoutRect.Contains(x, y);
}
var result = base.DispatchTouchEvent(e);
_ignoreNewFocus = false;
return result;
}
public override Android.Views.View CurrentFocus => _ignoreNewFocus ? null : base.CurrentFocus;

It'd be a bit of a hack, but you could spin off an async task that waits 50ms and then invokes the messageEntry.Focus() line on the main UI thread...
