Description

Kendo.DynamicLinqCore2 implements server paging, filtering, sorting and aggregating via Dynamic Linq for .Net Core2.0.

Build NuGet Package

1. Open command line console
2. Switch to project root directory.(src\Kendo.DynamicLinqCore2)
3. Run "dotnet restore"
4. Run "dotnet pack --configuration release"

Usage

1. Add the Kendo.DynamicLinqCore2 NuGet package to your project.

2. Configure your Kendo DataSource to send its options as JSON.

    parameterMap: function(options, type) {
        return JSON.stringify(options);
    }
   

3. Configure the schema of the DataSource.

    schema: {
        data: "Data",
        total: "Total",
        aggregates: "Aggregates",
        groups: "Group"
    }
   

4. Import the Kendo.DynamicLinqCore2 namespace.

5. Use the ToDataSourceResult extension method to apply paging, sorting and filtering.

    [WebMethod]
    public static DataSourceResult Products(int take, int skip, IEnumerable<Sort> sort, Filter filter, IEnumerable<Aggregator> aggregates, IEnumerable<Sort> group)
    {
        using (var northwind = new Northwind())
        {
            return northwind.Products
                .OrderBy(p => p.ProductID) // EF requires ordering for paging                    
                .Select(p => new ProductViewModel // Use a view model to avoid serializing internal Entity Framework properties as JSON
                {
                    ProductID = p.ProductID,
                    ProductName = p.ProductName,
                    UnitPrice = p.UnitPrice,
                    UnitsInStock = p.UnitsInStock,
                    Discontinued = p.Discontinued
                })
             .ToDataSourceResult(take, skip, sort, filter, aggregates, group);
        }
    }
