How to display static HTML string in Xamarin.Forms?
To display a static HTML string in Xamarin.Forms, you can use the WebView
control along with the HtmlWebViewSource
class. Here is a step-by-step guide on how to achieve this:
Create a WebView
in your XAML file:
<ContentPage xmlns="http://xamarin.com/schemas/2014/forms"
xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
x:Class="YourNamespace.YourPage">
<StackLayout>
<WebView x:Name="webView" HeightRequest="100" WidthRequest="200"/>
</StackLayout>
</ContentPage>
Set the HTML content in the code-behind file:
using Xamarin.Forms;
namespace YourNamespace
{
public partial class YourPage : ContentPage
{
public YourPage()
{
InitializeComponent();
var htmlSource = new HtmlWebViewSource
{
Html = @"<html><body>
<h1>Xamarin.Forms</h1>
<p>Welcome to WebView.</p>
</body></html>"
};
webView.Source = htmlSource;
}
}
}
This example demonstrates how to create a WebView
and set its source to an HTML string using the HtmlWebViewSource
class. The HTML content is directly embedded within the C# code, making it a static HTML string.
BaseUrl Property: If your HTML content references local resources (like images or CSS files), you need to set the BaseUrl
property to the appropriate path. This is particularly important for Android, iOS, and UWP platforms, as their file systems differ.
Binding HTML Content: If you need to bind the HTML content dynamically, you can use data binding in your ViewModel. Here is an example:
public class YourViewModel : INotifyPropertyChanged
{
private HtmlWebViewSource _htmlWebViewSource;
public HtmlWebViewSource HtmlWebViewSource
{
get { return _htmlWebViewSource; }
set
{
_htmlWebViewSource = value;
OnPropertyChanged();
}
}
public YourViewModel()
{
HtmlWebViewSource = new HtmlWebViewSource
{
Html = @"<html><body>
<h1>Xamarin.Forms</h1>
<p>Welcome to WebView.</p>
</body></html>"
};
}
public event PropertyChangedEventHandler PropertyChanged;
protected void OnPropertyChang...
