Hello,
I got the Hello World HTML client running in combination with the .Net Data adapter. The client is installed in the "LS/pages" folder.
Now I tried to create an ASP.net web application to run this example but the page is not updating.
Could you please help me what's the difference between running the client from the debug mode in visual studio (2015), and if it's installed directly into the LS server pages folder.
Valid code: index.html in LS/pages:
<!DOCTYPE html>

Here's the code of the asp.net page where the grid is not updating.
In debug mode the page is running under "local IIS" , project url: "
