JSExecutor.executeJS(..) is of type void, but i want to evaluate some javascript expression which returns a string value. How to do that? I am in the UI thread, i.e. it was triggered by a button click in the webpage.

Concrete, i want to evaluate JSExecutor.executeJS("window.external.MyMethod()"),
MyMethod is actually implemented as .NET method of type "string", and the webbrowser is embedded in a C# form. I cant use a Browser widget as MyMethod is defined only for the outermost browser window, not for an iframe.

This is currently not possible, the given JS is executed after, not
during the executeJS call. You can file an enhancement request in
bugzilla for this, but i cant say if and when it would be implemented.

You could probably use RAPs internal ajax infrastructure to get the
result to the server with the next http-request, but thats very hacky.

Greetings,
Tim
