WebView Navigated and Navigating events do not occur

[LanceMcCarthy]

Description

WebView's Navigated and Navigating events are not executing when website navigation occurs. This is easy to reproduce, see steps below for specific guidance.

Note: This has been previously reported, but was closed without a defined solution #3857

Steps to Reproduce

1. Create a new .NET MAUI preview13 project, add a ContentPage and use a WebView as the only page element
2. Subscribe to the Navigating and Navigated events, use any website for the Source
3. Use breakpoints or Debug.WriteLine in both event handlers to observe if the event handler is being executed
4. Start debugging the project (any platform, I repro on Android and WinUI)

Observe => The Navigating and Navigated event handlers are never executed.

Also important, although my steps show to use Android, this issue seems exists on every platform.

Here is code you can use:

<ContentPage ...>
    <WebView x:Name="WebView1"
                      Source="https://www.bing.com"
                      Navigating="WebView1_Navigating"
                      Navigated="WebView1_Navigated"/>
</ContentPage>

private async void WebView1_Navigating(object sender, WebNavigatingEventArgs e)
{
    Debug.WriteLine("Navigating Fired");
}

public async void WebView1_Navigated(object sender, WebNavigatedEventArgs e)
{
    Debug.WriteLine("Navigated Fired");
}

Version with bug

Preview 13 (current)

Last version that worked well

Unknown/Other

Affected platforms

Android, Windows, I was not able test on other platforms

Affected platform versions

Android 12 / API 31

Did you find any workaround?

I need anything that can give me the navigated to URL. Specifically, I need the query string, but nothing I tried works.

Relevant log output

I don't see any relevant output.

Hi team,

I wanted to provide a status update after bumping my project to use to preview14.

Android ✔

I am now seeing the Navigated event successfully fire and am getting the expected Url values!

Windows ✔

Windows (WinUI3) is working as well!

iOS/MacCatalyst ❓

WIP - will report back with results when VS 2022 Preview -> Mac deployments are working.

[edit] Updated test results after fixing problem with Windows deploy

Thanks for the follow up! Closing for now, please file a new issue if you find otherwise, but from my testing awhile back this should work in iOS/Catalyst now as well.
