Original Pull Request: https://github.com/radzenhq/radzen-blazor/pull/185

State: closed
Merged: No

This PR adds following:

ability to filter data with custom rules by assigning the RadzenDataGridColumn.CustomFiltering function in Client-side mode.
disabling unnecessary filtering/sorting operations in RadzenDataGrid.View in Server-side mode.
added related tests,
- DataGrid_View_Use_ClientSide_Filtering_When_LoadData_Empty
- DataGrid_View_Use_ServerSide_Filtering_When_LoadData_Used
- DataGrid_View_Use_Custom_Filtering

RadzenDataGridColumn custom filtering:

    [Parameter]
    public Func<CustomFilteringArgs<TItem>, bool> CustomFiltering { get; set; } = null;

    public class CustomFilteringArgs<T>
    {
        public Blazor.RadzenDataGridColumn<T> Column { get; internal set; }
        public T Data { get; internal set; }
    }

Trigger to this PR was the System.Linq.Dynamic.Core.Exceptions.ParseException that was thrown when trying to use RadzenDataGrid.View in event LoadData and active filter FilterOperator.Contains in a column with composite data, for example, an array of objects with fields [int Id], [string Name]
