Cefsharp browser JavaScript Binding not working

Anonymous — Wed, 25 Nov 2020 10:31:53 GMT

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
