But how I can databind my gridview in a webmethod?
Is there a way to bind it in JavaScript of how can I access it with a stati开发者_运维技巧c method?
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:
- Web Grid, Client side Binding VS. Server side HTML generation
- JQuery GridView control
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?
