Using custom filters

[kabbas]

Hello,

I'm wondering if I can use my custom developed filters with the multiselect, instead of being tied only to the ready-made ones (starts with, contains, equals)

I want to implement the custom filter server-side, i.e the multi-select makes an AJAX request with the query and the server makes the filtering then returns the results.

Thank you.

Hello,

If you have enabled server filtering you can implement the filtering on your own:

Check the following ASP.NET demo

http://demos.kendoui.com/web/multiselect/serverfiltering.html

the action method look like this and it could be easily changed:

public JsonResult GetProducts(string text)
{
    var northwind = new NorthwindDataContext();


    var products = northwind.Products.Select(product => new ProductViewModel
    {
        ProductID = product.ProductID,
        ProductName = product.ProductName,
        UnitPrice = product.UnitPrice ?? 0,
        UnitsInStock = product.UnitsInStock ?? 0,
        UnitsOnOrder = product.UnitsOnOrder ?? 0,
        Discontinued = product.Discontinued
    });

    if (!string.IsNullOrEmpty(text))
    {
        products = products.Where(p => p.ProductName.Contains(text));
    }

    return Json(products, JsonRequestBehavior.AllowGet);
}
