I have a ListView with an ItemTemplate & ViewCell defined in the xaml. My ViewCell contains a grid that has numerous Entry controls. When an Entry is clicked it gains focus, causing the keyboard to open. When the keyboard opens though the selected Entry loses focus and depending on the Android version it either selects the 1st entry in the grid at the top left ( Android 8.1 emulator) or just loses focus and selects nothing at all (9.0 Pixel 3XL).

Through various testing/hack attempts to fix this I've found that what is happening is that when the keyboard opens the ViewCell is recyling and the Entry that was previously selected is not actually in the UI anymore. I have tested this scenario using a very simple ListView with only 2 Entry controls in the ViewCell and nothing else and the same behavior is observed. If I select the 2nd Entry (bottom of StackLayout) it either loses focus and focuses on the 1st one when the keyboard opens, or loses focus completely (depends on Android version).

I feel that I must be missing something or doing something wrong, because this seems like an extremely common scenario and I cannot imagine that this is a bug no one has encountered yet. Below is the XAML for my ListView. This is my 1st post, so I apologize if I have done anything incorrectly.

Hi all,

Is it possible to add in XAML some condition checking ?

Like in the following pseudo code:

<ListView
    ItemsSource="{Binding Staffs}"
    HasUnevenRows="True">
    <ListView.ItemTemplate>
        <DataTemplate>
      <!-- How to add condition check for example -->
            <ViewCell>
                <!-- Check condition from context of model the Type of view and if choose the following view -->
                <views:OneView
                    BindingContext="{Binding .}"
                    HorizontalOptions="FillAndExpand"
                    VerticalOptions="FillAndExpand"/>
                <!-- else choose the following view -->
                <views:AnotherView
                    BindingContext="{Binding .}"
                    HorizontalOptions="FillAndExpand"
                    VerticalOptions="FillAndExpand"/>
                <!-- endif -->
            </ViewCell>
        </DataTemplate>
    </ListView.ItemTemplate>
</ListView>

Hello still learning here, I have a local html file it's already placed in the assets folder inside another foler called webview, I'm following the guide provided at https://docs.microsoft.com/en-us/xamarin/xamarin-forms/user-interface/webview, basically I'm using it to show a background video since I couldn't find a better way to do so in android.

The example as I understand, provides a way to fill the WebView with an HtmlWebViewSource

        var browser = new WebView();
        var htmlSource = new HtmlWebViewSource();

        htmlSource.Html = @"<html>
                            <head>
                            <link rel=""stylesheet"" href=""default.css"">
                            </head>
                            <body>
                            <h1>Xamarin.Forms</h1>
                            <p>The CSS and image are loaded from local files!</p>
                            <img src='XamarinLogo.png'/>
                            <p><a href=""local.html"">next page</a></p>
                            </body>
                            </html>";

        htmlSource.BaseUrl = DependencyService.Get<IBaseUrl>().Get();
        browser.Source = htmlSource;
        Content = browser;

But I just need to do something like WebVideo.Source = Url + "rain" + ".html";
The url is just string Url = "webview/";

The BaseUrl_Android class is already at the android folder and if I use the url in such way it appears like a blank page, all assets are set as androidasset in it's properties
it seems I don't know how to use these lines:

    htmlSource.BaseUrl = DependencyService.Get<IBaseUrl>().Get();
        browser.Source = htmlSource;

Any pointer here will be reatly appreciatted, thanks.

Hello, I'm trying to create an app for IOS and Android that loads created xaml pages from a server. There are several of these pages and it would be better that they are accessed by respective devices on load rather than stored locally on the devices as these forms are subject to changes and additional pages will be added frequently. All of the pages referenced will have cs file associated with them that will need to be accessed aswell.
The desired end result is an application that an loads has a list of all active pages/forms and when the user selects one of them, it will open, allow the user to fill it out and send it out.
Does anyone know if this is currently possible?

Would anyone know if it's possible to set the x:Class= in a xaml.cs file to a networked location?
Basically x:Class= "https://MyWebsiteStorage.com/files/Somefile.xaml.cs"

When I am going to pass parameter from Rg.Plugin.Popup page to a Content page,the content page will reload
so how to accept parameters from popup page to content page?

In my app there is an multiple line Editor.
So when I press the Enter key there is not Complete event to raise.
I want process the KeyPress event in XAML, but there is no KeyPress event can use in XAML.

My app has android and UWP version.
In android because the user can touch the Send button to do the work, so I don't need handle the Keypress event in android.
In UWP because the user will be press the Enter key to do the work, so I need handle the Keypress event in UWP.

I want to use some event which can write in XAML like this:
<Editor KeyPress="SendButton_KeyPress"/>

But I don't know which function or keywords to use.
Some one help me?
