You can absolutely use AJAX and web services to display tabular data (grids) in your ASP.NET applications. These StackOverflow questions offer a good introduction to several different options:
However, you cannot literally databind GridView or DataGrid controls in javascript functions. The grid controls are server-side objects, deeply integrated into the ASP.NET page lifecycle.
ASP.NET controls only exist inside Page instances – and no page instance is created during the execution of static WebMethods. For a great explanation of this, see Why do ASP.NET AJAX page methods have to be static?
