ER bind Unable to find the Engine

**eduramires** · January 29th, 2008, 02:53 PM

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.

Hi there!
After I wrote my problem, I read the documentation again and I found a doc that I hadn't read yet and it was my salvation, (lol). Now, everything is working fine.
Thanks anyway.

Which doc did you have to read. I am also trying to build a .aspx page and I am getting the error which I posted in the thread "ASP.NET error Please help."
Do yo think you can figure out the reason for the error.
