Cefsharp browser JavaScript Binding not working

[Anonymous]

Hello Forum,

For the current addin I am developing I have implemented a CefSharp browser inside of a DockableDialog loading a local .html page. Currently I am trying to bind a .Net class and call its functions from the Webpage via JavaScript Binding of CefSharp (https://github.com/cefsharp/cefsharp/issues/2246). But I have run into the following issues:

• When trying to bind the object via CefSharp.BindObjectAsync() from the Webpage it won't bind the object at all.
• When trying to bind the object via browser.ExecuteScriptAsync("CefSharp.BindObjectAsync();") it will bind the object but I am unable to call its functions afterwards.

This is the code I have:

• Binding the object in JS and calling the showMessage function on button click:

function CallAddin()
{
	(async function()
	{
		console.log("HERE");
		await CefSharp.BindObjectAsync("bound");
		bound.showMessage();
	})();
}

• Resolve the binding of the object and check if successfully bound in C#:

browser = new ChromiumWebBrowser(); browser.JavascriptObjectRepository.ResolveObject += (sender, e) => 
{ 
    var repo = e.ObjectRepository; 
    if (e.ObjectName == "bound") 
    { 
        repo.Register("bound", new Translate(), isAsync: true, options: new BindingOptions()); 
    } 
}; 
browser.JavascriptObjectRepository.ObjectBoundInJavascript += (sender, e) => 
{ 
    var name = e.ObjectName; 
    TaskDialog.Show("Info", "Successfully bound object"); 
};

•  The class to bind to the Webpage:

class Translate
{
    public void ShowMessage()
    {
        TaskDialog.Show("Info", "This was called from the Webpage");
    }
}

 I use:

• Revit2020
• CefSharp 65.0.1
• .NET Framework 4.7.2

Cheers
