I am trying to automate a website data extraction by dynamically creating a webview and loading the source url. I want the page and webview to be NOT to be displayed to the user. Unfortunately the events seems not working. Any help appreciated

Here is what I am trying to do:

ContentPage cp = new ContentPage();
    cp.Title = "My Page";
    StackLayout sl = new StackLayout();
    var webView = new WebView();

    sl.Children.Add(webView);
    cp.Content = sl;

    webView.Navigating += WebView_Navigating;
    webView.Navigated += WebView_Navigated;

    webView.Source = "https://www.google.com/";//just a sample i tried multiple urls including http


private async void WebView_Navigating(object sender, WebNavigatingEventArgs e)
{
    //event not firing!
}

private async void WebView_Navigated(object sender, WebNavigatedEventArgs e)
{
    //event not firing!
}

I followed the Visual Studio suggestion to install "Microsoft.CodeAnalysis.FxCopAnalyzers" and suddenly I get tons of new warnings.
One of them is:

Consider calling ConfigureAwait on the awaited task

So basically my await calls should change from:
await NavigationService.NavigateAsync("Navigation/Login")
to
await NavigationService.NavigateAsync("Navigation/Login").ConfigureAwait(false)

I tried to read the documentation but I am not sure about the benefit of it.
Would you recommend to make that change to all my await calls?

Thanks!

I have the a TabbedPage Application and want to change the textcolor at runtime.

<Label Text="Color change works for this label, as i set textcolor" TextColor="{DynamicResource MyTextColor}"/>
<Label Text="but i want to have it work for all labels and other elements without DynamicResource=MyTextColor"/>

public partial class TabPage : ContentPage
protected override void OnAppearing()
{
    // this works
    Resources["MyTextColor"] = DarkTheme ? Color.Red : Color.Blue;

    // this does not work at runtime, textcolor defined in styles <item name="android:textColor">#43d5e6</item> does not update at runtime
    SetTheme(DarkTheme ? Resource.Style.MainTheme_Dark: Resource.Style.MainTheme_Light);
}

item name="android:textColor> is differently defined in MainTheme_Dark and MainTheme_Light and gets at once applied to new Pages (for example Navigation.PushModalAsync(new NavigationPage(new NewPage())), but it gets not applied to existing TabPage. I have to close my app and only afterwards, it correctly applies the new "item name=android:textColor> from the selected MainTheme.

How can I force to change android:textColor at runtime in the OnAppearing()-event?

I need to design the CollectionView with Header in XAML, how to do this?

I updated my iPad to 13.2, updated to latest XCode on my mac, updated VS, updated to XF 4.3.

I know, not smart.

Everything appeared to work, until I tried the SHARE function of my app on iPad. The pop-over does not appear. An older version of my app works OK, and the new version works OK on my iPhone running 13.1.3.

I did try rolling back XF to what I was using (since it was easy), no help there.

Oh, and well there's another part to this mystery. To share multiple files, I wrote my own code using the iOS api, including creating an Activity Vew Controller (the pop-over). This doesn't work either.

Is there some kind of iPad settings or Info.plist thing I'm missing here? Got me very confused.

im making and ios android app and want to use mapbox because most xamarin forms maps look horrible and are expensive and also mapbox is very customizeable. i hear the defualt xamarin forms mapbox sdk is very glitchy and has not been updated and was wondering if there was a better way such as installing ios and android nuget mapbox sdks on their own platform and some how implementing them seprately in the designer. or good maps other recomendation that dont look like they were made 2005 lol.
