Description

How can I access all requested filters recursively and modify them on the server?

Solution

You can achieve this requirement using the following implementation:

Configure the Grid for Ajax data binding.

Razor

@(Html.Kendo().Grid<Telerik.Examples.Mvc.Areas.GridModifyFiltersOnTheServer.Models.Order>()
    .Name("grid")
    .Filterable()
    .DataSource(dataSource => dataSource
        .Ajax()
        .Read(read => read.Action("Read", "Home"))
        ... // Additional options.
    )
    ... // Additional configuration.
)

Retrieve the requested filters through the DataSourceRequest object and adjust filter criteria on the server side before processing the request.

public ActionResult Read([DataSourceRequest] DataSourceRequest request)
{
    ModifyFilters(request.Filters);

    return Json(OrderRepository.GetAll().ToDataSourceResult(request));
}

private void ModifyFilters(IEnumerable<IFilterDescriptor> filters)
{
    if (filters.Any())
    {
        foreach (var filter in filters)
        {
            var descriptor = filter as FilterDescriptor;
            if (descriptor != null && descriptor.Member == "OrderDate")
            {
                descriptor.Member = "OrderDate.Date";
            }
            else if (filter is CompositeFilterDescriptor)
            {
                ModifyFilters(((CompositeFilterDescriptor)filter).FilterDescriptors);
            }
        }
    }
}
