Execute a command within a WebView C#

Question

I am using WPF and have used the Microsoft.Toolkit.Wpf.UI.Controls.WebView control to host the webpage for a simple online game. The game has a button that makes the root content stretch to fullscreen (as the window).

This button is simply defined in the HTML as <div class="fullscreen" onclick="unityInstance.SetFullscreen(1)"></div>

I can open the console in a web browser and run unityInstance.SetFullscreen(1), but I want to do that within my webview. I've tried MainView.InvokeScript("eval", new[] { "unityInstance.SetFullscreen(1)" }); but that just throws an exception HRESULT: 0x80020101

Ignore the "fullscreen" part of the question -- I just want to run that command in the webview. Is that possible? Thanks.

I would recommend you to enable scripts and try to invoke your script this way:

MainView.IsScriptEnabled = true;
MainView.InvokeScript("eval", new string[] { "unityInstance.SetFullscreen(1);" });

I set IsJavaScriptEnabled property to true and this worked perfectly as expected. I'm wondering how I didn't do that. Thanks!
