Here is a complete guide on how to handle internet connection issues in a MAUI app with a WebView, including showing a message when the connection is lost.

MainPage.xaml

First, let's define the structure of your MainPage.xaml with a WebView and a Label to show the connection status:

xmlCopy code <ContentPage xmlns="http://schemas.microsoft.com/dotnet/2021/maui" xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml" xmlns:local="clr-namespace:MauiApp2" x:Class="MauiApp2.MainPage" BackgroundColor="{DynamicResource PageBackgroundColor}">

MainPage.xaml.cs

Next, let's handle the internet connection status in the code-behind file:

csharpCopy code using

Explanation

MainPage.xaml:

Added a Label named connectionStatusLabel to display the connection status message.

The WebView is named webview and set to display a website URL .

MainPage.xaml.cs:

In the constructor, the CheckInternetConnection method is called to check the initial connection status.

Subscribed to the ConnectivityChanged event to handle changes in the network connectivity.

The CheckInternetConnection method checks the current network access and updates the visibility of the Label and WebView accordingly.

When the network connectivity changes, the Connectivity_ConnectivityChanged event handler calls CheckInternetConnection to update the UI.

This setup ensures that when the internet connection is lost, the WebView is hidden, and a message is displayed to the user. When the connection is restored, the WebView becomes visible again, and the message is hidden.

Hello,

MAUI officially provides a way to detect connectivity.

You could use the following code to alert users when the network is limited or when they lose connection.

//Add this line of code to the page's constructor
Connectivity.ConnectivityChanged += Connectivity_ConnectivityChanged;

void Connectivity_ConnectivityChanged(object sender, ConnectivityChangedEventArgs e)
{
    if (e.NetworkAccess == NetworkAccess.ConstrainedInternet)
        DisplayAlert("Warning", "Internet access is available but is limited.", "OK");

    else if (e.NetworkAccess != NetworkAccess.Internet)
        DisplayAlert("Warning", "Internet access has been lost.", "OK");
}

Please refer to the Connectivity for more information.

Best Regards,

Alec Liu.
