NSG.PrimeNG.LazyLoading

NSG.PrimeNG.LazyLoading is a project in support of TurboTable lazy and filter features. This allows for remote pagination, filtering and sorting using a .Net MVC API.

Example from original LazyLoadEvent unit tests:

    string _jsonString =
            "{\"first\":0,\"rows\":3," +
            "\"sortOrder\":-1,\"sortField\":\"NoteTypeSortOrder\"," +
            "\"filters\":{\"NoteTypeDesc\":{\"value\":\"SO\",\"matchMode\":\"StartsWith\"}}}";
    JavaScriptSerializer _js_slzr = new JavaScriptSerializer();
    LazyLoadEvent _loadEvent = (LazyLoadEvent)_js_slzr.Deserialize(_jsonString, typeof(LazyLoadEvent));
    List<NoteType> _rows = NoteTypes.AsQueryable()
            .LazyOrderBy(_loadEvent)
            .LazyFilters(_loadEvent)
            .LazySkipTake(_loadEvent).ToList();

The PrimeNG definition of LazyLoadEvent is wrong. What is returned from the lazy interface event for the filter is not a single FilterMetadata, but an array of FilterMetadata. It allows for 'or' conditional on the element being filtered. See github issue 10055 or my issue 10269.

Example of corrected LazyLoadEvent2 interface test:

    string _jsonString = "{\"first\":0,\"rows\":3," +
        "\"sortOrder\":-1,\"sortField\":\"NoteTypeSortOrder\"," +
        "{\"filters\":{\"NoteTypeDesc\":[" +
        "{\"value\":\"SO\",\"matchMode\":\"startsWith\",\"operator\":\"or\"}," +
        "{\"value\":\"6\",\"matchMode\":\"contains\",\"operator\":\"or\"}]}}";
    LazyLoadEvent2 _loadEvent = JsonConvert.DeserializeObject<LazyLoadEvent2>(_jsonString);
    List<NoteType> _rows = NoteTypes.AsQueryable()
        .LazyOrderBy2<NoteType>(_loadEvent)
        .LazyFilters2<NoteType>(_loadEvent)
        .LazySkipTake2<NoteType>(_loadEvent).ToList();

NSG.PrimeNG.LazyLoading_Tests

NSG.PrimeNG.LazyLoading_Tests is a .Net Core project of unit tests for the LazyLoading library.

Wiki

The Wiki pages were initialy created by the CS2Wiki.awk scripts with the library's XML file. The AWK scripts is a hack and got me 70% of the way to creating the MediaWiki file. Make sure the text is flush left except for code. Code is indented by two spaces. The mediwiki scripts have been moved here.
