    .Name("Grid")
    .Pageable()
    .EnableCustomBinding(true) 
    .Columns(columns =>

    columns.Bound(e => e.BankFileNo);
    })
    .DataSource(dataSource => dataSource
    .Ajax()
    .Model(model => model.Id(o => o.Id))
    .Read(read => read.Action("FilterFiles_Read","File").Data("GetValues"))

        .Total(TempData["Total"] == null ? 0 : (int)TempData["Total"])
    )
)

Do i must configure iis or must change applicaion? please help me

@zeinab kalanaki, Do you still have problem? The solution in following ASP.Net MVC $.Ajax() function not working when hosted in IIS7 helped me fixed mine. Try amending your url to

url: '@Url.Action("IsLoanNumberValid", "File")/',

Notice the added '/' at the end. seems like a bug to me.
