Jquery DataTables Asp.Net Core Server Side

This repository is a Server Side processor for Jquery DataTables with Asp.Net Core as backend. It provides a quick way to implement dynamic multiple column searching and sorting along with pagination and excel export at the server side. This can be done by decorating your model properties with simple attributes.

Demo Implementation Project URL - Free Download

Note: This tutorial contains example for both AJAX GET and AJAX POST Server Side Configuration.

Warning: If we are RESTful strict, we should use GET Method to get information not POST but I prefer this way to avoid limitations related to form data through the query string, so up to you if you want to use GET. I recommend using AJAX GET only if your DataTable has very less number of columns. As Jquery DataTables AJAX requests produces too large query string which will be rejected by server.

Wait - Why JqueryDataTablesServerSide ?

Well... there are lots of different approaches how to get a Jquery DataTables with Asp.Net Core app running. I thought it would be nice for .NET devs to use the ASP.NET Core backend and just decorate the model properties with a pretty simple attributes called [Searchable] and [Sortable]. [DisplayName(“”)] as the name suggests, can be used to change the column name in excel export or display name in the table HTML. I just combine ASP.NET Core & Jquery DataTables for easy server side processing.

Compatibility Chart

The following chart describes the operator compatibility with data types with green as compatible and red as not compatible.

NuGet:

JqueryDataTables.ServerSide.AspNetCoreWeb v2.2.0

Usage:

To activate and make Jquery DataTable communicate with asp.net core backend,

Package Manager:

PM> Install-Package JqueryDataTables.ServerSide.AspNetCoreWeb

.NET CLI:

> dotnet add package JqueryDataTables.ServerSide.AspNetCoreWeb

Startup.cs

public void ConfigureServices(IServiceCollection services)
{
    services.AddMvc();
    services.AddSession();
    services.AddJqueryDataTables();
    services.AddAutoMapper(typeof(Startup));
}

Please note: services.AddSession() is is required only if you're using excel export functionality in Jquery DataTables.

Tag Helpers

Add a JqueryDataTables TagHelper reference to your _ViewImports.cshtml file as shown below

@addTagHelper *, JqueryDataTables.ServerSide.AspNetCoreWeb

Table HTML

I have written <jquery-datatables> TagHelper to do the heavy lifting works for you.

<jquery-datatables id="fingers10"
                   class="table table-sm table-dark table-bordered table-hover"
                   model="@Model"
                   thead-class="text-center"
                   enable-searching="true"
                   search-row-th-class="p-0"
                   search-input-class="form-control form-control-sm"
                   search-input-style="width: 100%"
                   search-input-placeholder-prefix="Search">
</jquery-datatables>

TagHelpers Attributes

id - to add id to the html table
class - to apply the given css class to the html table
model - view model with properties to generate columns for html table
thead-class - to apply the given css class to the <thead> in html table
enable-searching - true to add search inputs to the <thead> and false to remove search inputs from the <thead>
search-row-th-class - to apply the given css class to the search inputs row of the <thead> in the html table
search-input-class - to apply the given css class to the search input controls added in each column inside <thead>
search-input-style - to apply the given css styles to the search input controls added in each column inside <thead>
search-input-placeholder-prefix - to apply your placeholder text as prefix in search input controls in each column inside <thead>

Initialize DataTable

Add the following code to initialize DataTable. Don't miss to add orderCellsTop : true. This makes sure to add sorting functionality to the first row in the table header. For other properties refer Jquery DataTables official documentation.

Use AdditionalValues to pass extra parameters if required to the server for processing. Configure Column properties and add the required search operator in the name property to perform search based on the operator in the name property. If name property is null or string.Empty, the search default's to Equals search operation.

Please note: Search Operator must be one among the following eq | co | gt | gte | lt | lte based on the above compatibility chart.

AJAX POST Configuration

var table = $('#fingers10').DataTable({
        language: {
            processing: "Loading Data...",
            zeroRecords: "No matching records found"
        },

        buttons: [
            {
                text: 'Export to Excel',
                className: 'btn btn-sm btn-dark',
                action: function (e, dt, node, config) {
                    window.location.href = "/Home/GetExcel";
                },
                init: function (api, node, config) {
                    $(node).removeClass('dt-button');
                }
            }
        ],
        ajax: {
            type: "POST",
            url: '/Home/LoadTable/',
            contentType: "application/json; charset=utf-8",
            async: true,
            headers: {
                "XSRF-TOKEN": document.querySelector('[name="__RequestVerificationToken"]').value
            },
            data: function (data) {
                let additionalValues = [];
                additionalValues[0] = "Additional Parameters 1";
                additionalValues[1] = "Additional Parameters 2";
                data.AdditionalValues = additionalValues;

                return JSON.stringify(data);
            }
        },
        columns: [
            {
                data: "Id",
                name: "eq",
                visible: false,
                searchable: false
            },
            {
                data: "Name",
                name: "eq"
            },
            {
                data: "Position",
                name: "co"
            },
            {

            },
            {
                data: "DemoNestedLevelOne.Experience",
                name: "eq"
            },
            {
                data: "DemoNestedLevelOne.Extension",
                name: "eq"
            },
            {
                data: "DemoNestedLevelOne.DemoNestedLevelTwos.StartDates",
                render: function (data, type, row) {
                    if (data)
                        return window.moment(data).format("DD/MM/YYYY");
                    else
                        return null;
                },
                name: "gt"
            },
            {
                data: "DemoNestedLevelOne.DemoNestedLevelTwos.Salary",
                name: "lte"
            }
        ]
    });

AJAX GET Configuration

For AJAX GET configuration, simply change the ajax and buttons options as follows,

buttons: [
            {
                text: 'Export to Excel',
                className: 'btn btn-sm btn-dark',
                action: function (e, dt, node, config) {
                    var data = table.ajax.params();
                    var x = JSON.stringify(data, null, 4);
                    window.location.href = "/Home/GetExcel?" + $.param(data);
                },
                init: function (api, node, config) {
                    $(node).removeClass('dt-button');
                }
            }
        ],
ajax: {
            url: '/Home/LoadTable/',
            data: function (data) {
                return $.extend({}, data, {
                    "additionalValues[0]": "Additional Parameters 1",
                    "additionalValues[1]": "Additional Parameters 2"
                });
            }
       }

Trigger Search

Add the following script to trigger search only onpress of Enter Key.

table.columns().every(function (index) {
        $('#fingers10 thead tr:last th:eq(' + index + ') input')
            .on('keyup',
                function (e) {
                    if (e.keyCode === 13) {
                        table.column($(this).parent().index() + ':visible').search(this.value).draw();
                    }
                });
    });

Add the following script to trigger search onpress of Tab Key

$('#fingers10 thead tr:last th:eq(' + index + ') input')
    .on('blur',
	    function () {
		    table.column($(this).parent().index() + ':visible').search(this.value).draw();
       });

Model to be passed to DataTable

Decorate the properties based on their data types. For Nested Complex Properties, decorate them with [NestedSearchable]/[NestedSortable] attributes upto any level.

Root Model:

public class Demo
{
    public int Id { get; set; }

    [SearchableString]
    [Sortable(Default = true)]
    public string Name { get; set; }

    [SearchableString]
    [Sortable]
    public string Position { get; set; }

    [SearchableString(EntityProperty = "Office")]
    [Sortable(EntityProperty = "Office")]
    public string Offices { get; set; }

    [NestedSearchable]
    [NestedSortable]
    public DemoNestedLevelOne DemoNestedLevelOne { get; set; }
}

Nested Level One Model:

public class DemoNestedLevelOne
{
    [SearchableShort]
    [Sortable]
    public short? Experience { get; set; }

    [SearchableInt(EntityProperty = "Extn")]
    [Sortable(EntityProperty = "Extn")]
    public int? Extension { get; set; }

    [NestedSearchable(ParentEntityProperty = "DemoNestedLevelTwo")]
    [NestedSortable(ParentEntityProperty = "DemoNestedLevelTwo")]
    public DemoNestedLevelTwo DemoNestedLevelTwos { get; set; }
}

Nested Level Two Model:

public class DemoNestedLevelTwo
{
    [SearchableDateTime(EntityProperty = "StartDate")]
    [Sortable(EntityProperty = "StartDate")]
    [DisplayName("Start Date")]
    public DateTime? StartDates { get; set; }

    [SearchableLong]
    [Sortable]
    public long? Salary { get; set; }
}

Please note: If view model properties have different name than entity model then, you can still do mapping using (EntityProperty = 'YourEntityPropertyName'). If they are same then you can ignore this.

ActionMethod/PageHandler

On DataTable's AJAX Request, JqueryDataTablesParameters will read the DataTable's state and JqueryDataTablesResult<T> will accept IEnumerable<T> response data to be returned back to table as JsonResult.

AJAX POST Configuration

ActionMethod

[HttpPost]
public async Task<IActionResult> LoadTable([FromBody]JqueryDataTablesParameters param)
{
    try
    {
        // `param` is stored in session to be used for excel export. This is required only for AJAX POST.
        // Below session storage line can be removed if you're not using excel export functionality. 
        HttpContext.Session.SetString(nameof(JqueryDataTablesParameters),JsonConvert.SerializeObject(param));
        var results = await _demoService.GetDataAsync(param);

        return new JsonResult(new JqueryDataTablesResult<Demo> {
            Draw = param.Draw,
            Data = results.Items,
            RecordsFiltered = results.TotalSize,
            RecordsTotal = results.TotalSize
        });
    } catch(Exception e)
    {
        Console.Write(e.Message);
        return new JsonResult(new { error = "Internal Server Error" });
    }
}

PageHandler

public async Task<IActionResult> OnPostLoadTableAsync([FromBody]JqueryDataTablesParameters param)
{
    try
    {
        // `param` is stored in session to be used for excel export. This is required only for AJAX POST.
        // Below session storage line can be removed if you're not using excel export functionality. 
        HttpContext.Session.SetString(nameof(JqueryDataTablesParameters),JsonConvert.SerializeObject(param));
        var results = await _demoService.GetDataAsync(param);

        return new JsonResult(new JqueryDataTablesResult<Demo> {
            Draw = param.Draw,
            Data = results.Items,
            RecordsFiltered = results.TotalSize,
            RecordsTotal = results.TotalSize
        });
    } catch(Exception e)
    {
        Console.Write(e.Message);
        return new JsonResult(new { error = "Internal Server Error" });
    }
}

AJAX GET Configuration

ActionMethod

public async Task<IActionResult> LoadTable(JqueryDataTablesParameters param)
{
    try
    {
        var results = await _demoService.GetDataAsync(param);

        return new JsonResult(new JqueryDataTablesResult<Demo> {
            Draw = param.Draw,
            Data = results.Items,
            RecordsFiltered = results.TotalSize,
            RecordsTotal = results.TotalSize
        });
    } catch(Exception e)
    {
        Console.Write(e.Message);
        return new JsonResult(new { error = "Internal Server Error" });
    }
}

PageHandler

public async Task<IActionResult> OnGetLoadTableAsync(JqueryDataTablesParameters param)
{
    try
    {
        var results = await _demoService.GetDataAsync(param);

        return new JsonResult(new JqueryDataTablesResult<Demo> {
            Draw = param.Draw,
            Data = results.Items,
            RecordsFiltered = results.TotalSize,
            RecordsTotal = results.TotalSize
        });
    } catch(Exception e)
    {
        Console.Write(e.Message);
        return new JsonResult(new { error = "Internal Server Error" });
    }
}

Multiple Column Searching and Sorting

Inject Automapper IConfigurationProvider to make use of ProjectTo<T> before returning the data. Inside the Data Access Method, create IQueryable<TEntity> to hold the query. Now, to perform dynamic multiple column searching create a instance of Search Processor new SearchOptionsProcessor<T,TEntity>() and call the Apply() function with query and table columns as parameters. Again for dynamic multiple column sorting, create a instance of Sort Processor new SortOptionsProcessor<T,TEntity>() and call the Apply() function with query and table as parameters. To implement pagination, make use of Start and Length from table parameter and return the result as JqueryDataTablesPagedResults.

public class DefaultDemoService:IDemoService
{
    private readonly Fingers10DbContext _context;
    private readonly IConfigurationProvider _mappingConfiguration;

    public DefaultDemoService(Fingers10DbContext context,IConfigurationProvider mappingConfiguration)
    {
        _context = context;
        _mappingConfiguration = mappingConfiguration;
    }

    public async Task<JqueryDataTablesPagedResults<Demo>> GetDataAsync(JqueryDataTablesParameters table)
    {
        IQueryable<DemoEntity> query = _context.Demos
                                               .AsNoTracking()
                                               .Include(x => x.DemoNestedLevelOne)
                                               .ThenInclude(y => y.DemoNestedLevelTwo);
        query = new SearchOptionsProcessor<Demo,DemoEntity>().Apply(query,table.Columns);
        query = new SortOptionsProcessor<Demo,DemoEntity>().Apply(query,table);

        var size = await query.CountAsync();

        var items = await query
            .AsNoTracking()
            .Skip((table.Start / table.Length) * table.Length)
            .Take(table.Length)
            .ProjectTo<Demo>(_mappingConfiguration)
            .ToArrayAsync();

        return new JqueryDataTablesPagedResults<Demo> {
            Items = items,
            TotalSize = size
        };
    }
}

Please note: If you are having DataAccessLogic in a separate project, the create instance of SearchOptionsProcessor and SortOptionsProcessor inside ActionMethod/Handler and pass it as a parameter to Data Access Logic.

Excel Export

To exporting the filtered and sorted data as an excel file, add GetExcel action method in your controller as shown below. Return the data as JqueryDataTablesExcelResult<T> by passing filtered/ordered data, excel sheet name and excel file name. JqueryDataTablesExcelResult Action Result that I have added in the Nuget package. This will take care of converting your data as excel file and return it back to browser.

If you want all the results in excel export without pagination, then please write a separate service method to retrive data without using Take() and Skip()

AJAX POST Configuration

Action Method

public async Task<IActionResult> GetExcel()
{
   // Here we will be getting the param that we have stored in the session in server side action method/page handler
   // and deserialize it to get the required data.
   var param = HttpContext.Session.GetString(nameof(JqueryDataTablesParameters));

   var results = await _demoService.GetDataAsync(JsonConvert.DeserializeObject<JqueryDataTablesParameters>(param));
   return new JqueryDataTablesExcelResult<DemoExcel>(_mapper.Map<List<DemoExcel>>(results.Items),"Demo Sheet Name","Fingers10");
}

Page Handler

public async Task<IActionResult> OnGetExcelAsync()
{
  // Here we will be getting the param that we have stored in the session in server side action method/page handler
  // and deserialize it to get the required data.
  var param = HttpContext.Session.GetString(nameof(JqueryDataTablesParameters));

  var results = await _demoService.GetDataAsync(JsonConvert.DeserializeObject<JqueryDataTablesParameters>(param));
  return new JqueryDataTablesExcelResult<DemoExcel>(_mapper.Map<List<DemoExcel>>(results.Items),"Demo Sheet Name","Fingers10");
}

AJAX GET Configuration

Action Method

public async Task<IActionResult> GetExcel(JqueryDataTablesParameters param)
{
    var results = await _demoService.GetDataAsync(param);
    return new JqueryDataTablesExcelResult<DemoExcel>(_mapper.Map<List<DemoExcel>>(results.Items),"Demo Sheet Name","Fingers10");
}

Page Handler

public async Task<IActionResult> OnGetExcelAsync(JqueryDataTablesParameters param)
{
    var results = await _demoService.GetDataAsync(param);
    return new JqueryDataTablesExcelResult<DemoExcel>(_mapper.Map<List<DemoExcel>>(results.Items),"Demo Sheet Name","Fingers10");
}

Please note: GetExcel ActionMethod/Handler name must match the name you define in the excel export action click in your Jquery DataTable Initialization script. For getting excel file from complex models/mappings, either project the results to final simple model or use automapper flattening feature to map the results from complex model to simple model.
