Hi there,
I need some help.
I built a Custom GridView using .NET (C#) to render a table as LS needs and a helper class that put all LightStreamer js scripts on the page. I'm using the STOCKLISTDEMO application that comes with the evaluation version of LS, running on port 8080 in my developer machine. The pages are served by IIS, in the same machine.
But it doesn't work. After a few seconds that pages was load, I receive the message "ER bind Unable to find the Engine".
Below follows the code generated by my custom grid view and my helper class.
