Getting Started with Blazor Pivot Table in Blazor Web App

29 Nov 202424 minutes to read

This section briefly explains about how to include Blazor Pivot Table component in your Blazor Web App using Visual Studio.

Prerequisites

System requirements for Blazor components

Create a new Blazor Web App

You can create a Blazor Web App using Visual Studio 2022 via Microsoft Templates or the Syncfusion^® Blazor Extension.

You need to configure the corresponding Interactive render mode and Interactivity location while creating a Blazor Web Application.

Install Syncfusion^® Blazor PivotTable and Themes NuGet in the App

To add Blazor Pivot Table component in the app, open the NuGet package manager in Visual Studio (Tools → NuGet Package Manager → Manage NuGet Packages for Solution), search and install Syncfusion.Blazor.PivotTable and Syncfusion.Blazor.Themes.

If you utilize WebAssembly or Auto render modes in the Blazor Web App need to be install Syncfusion^® Blazor components NuGet packages within the client project.

Alternatively, you can utilize the following package manager command to achieve the same.

Package Manager
Install-Package Syncfusion.Blazor.PivotTable -Version 28.1.33
Install-Package Syncfusion.Blazor.Themes -Version 28.1.33

NOTE

Syncfusion^® Blazor components are available in nuget.org. Refer to NuGet packages topic for available NuGet packages list with component details.

Register Syncfusion^® Blazor Service

Open ~/_Imports.razor file and import the Syncfusion.Blazor and Syncfusion.Blazor.PivotView namespace .

@using Syncfusion.Blazor
@using Syncfusion.Blazor.PivotView

Now, register the Syncfusion^® Blazor Service in the ~/Program.cs file of your Blazor Web App.

If you select an Interactive render mode as WebAssembly or Auto, you need to register the Syncfusion^® Blazor service in both ~/Program.cs files of your Blazor Web App.

....
using Syncfusion.Blazor;
....
builder.Services.AddSyncfusionBlazor();
....

Add stylesheet and script resources

The theme stylesheet and script can be accessed from NuGet through Static Web Assets. Include the stylesheet reference in the <head> section and the script reference at the end of the <body> in the ~/Components/App.razor file as shown below:

<head>
    ....
    <link href="_content/Syncfusion.Blazor.Themes/bootstrap5.css" rel="stylesheet" />
</head>

<body>
    ....
    <script src="_content/Syncfusion.Blazor.Core/scripts/syncfusion-blazor.min.js" type="text/javascript"></script>
</body>

NOTE

Check out the Blazor Themes topic to discover various methods (Static Web Assets, CDN, and CRG) for referencing themes in your Blazor application. Also, check out the Adding Script Reference topic to learn different approaches for adding script references in your Blazor application.

Initializing Blazor pivot Table component

Add the Syncfusion^® Blazor pivot Table component in the ~Pages/.razor file. If an interactivity location as Per page/component in the web app, define a render mode at the top of the ~Pages/.razor component, as follows:

RAZOR

@* desired render mode define here *@
@rendermode InteractiveAuto

RAZOR
<SfPivotView TValue="ProductDetails"></SfPivotView>

Assigning sample data to the Blazor pivot table

The Blazor Pivot Table component further needs to be populated with an appropriate data source. For illustration purpose, a collection of objects mentioning the sales details of certain products over a period and region has been prepared. This sample data is assigned to the pivot table component through DataSource property under PivotViewDataSourceSettings class.

RAZOR
<SfPivotView TValue="ProductDetails">
     <PivotViewDataSourceSettings DataSource="@dataSource">
    </PivotViewDataSourceSettings>
</SfPivotView>

@code{
    public List<ProductDetails> dataSource { get; set; }
    protected override void OnInitialized()
    {
        this.dataSource = ProductDetails.GetProductData().ToList();
    }

    public class ProductDetails
    {
        public int Sold { get; set; }
        public double Amount { get; set; }
        public string Country { get; set; }
        public string Products { get; set; }
        public string Year { get; set; }
        public string Quarter { get; set; }

        public static List<ProductDetails> GetProductData()
        {
            List<ProductDetails> productData = new List<ProductDetails>();
            productData.Add(new ProductDetails { Sold = 31, Amount = 52824, Country = "France", Products = "Mountain Bikes", Year = "FY 2015", Quarter = "Q1" });

            return productData;
        }
    }
}

Adding fields to row, column, value and filter axes

Now that pivot table is initialized and assigned with sample data, will further move to showcase the component by organizing appropriate fields in row, column, value and filter axes.

In PivotViewDataSourceSettings class, four major axes - PivotViewRows, PivotViewColumns, PivotViewValues and PivotViewFilters plays a vital role in defining and organizing fields from the bound data source, to render the entire pivot table component in a desired format.

PivotViewRows – Collection of fields that needs to be displayed in row axis of the pivot table.

PivotViewColumns – Collection of fields that needs to be displayed in column axis of the pivot table.

PivotViewValues – Collection of fields that needs to be displayed as aggregated numeric values in the pivot table.

PivotViewFilters - Collection of fields that would act as master filter over the data bound in row, column and value axes of the pivot table.

In-order to define each field in the respective axis, the following basic properties should be set.

Name: It allows to set the field name from the bound data source. It’s casing should match exactly like in the data source and if not set properly, the pivot table will not be rendered.
Caption: It allows to set the field caption, which is the alias name of the field that needs to be displayed in the pivot table.
Type: It allows to set the summary type of the field. By default, SummaryTypes.Sum is applied.

Applying formatting to a value field

Formatting defines a way in which values should be displayed. For example, format “C” denotes the values should be displayed in currency pattern. To do so, define the PivotViewFormatSetting class with its Name and Format properties and add it to PivotViewFormatSettings. In this illustration, the Name property is set as Amount, a field from value section and its format is set as currency. Likewise, we can set format for other value fields as well and add it to PivotViewFormatSettings.

NOTE

Only fields from value section, which is in the form of numeric data values are applicable for formatting.

Enable Field List

The field list allows to add or remove fields and also rearrange the fields between different axes, including column, row, value, and filter along with filter and sort options dynamically at runtime. It can be enabled by setting the ShowFieldList property to true. To know more about field list, refer here.

Enable Grouping Bar

The grouping bar feature automatically populates fields from the bound data source and allows end users to drag fields between different axes such as columns, rows, values, and filters, and alter pivot table at runtime. It also provides option to sort, filter and remove fields. It can be enabled by setting the ShowGroupingBar property to true. To know more about grouping bar, refer here.

Exploring Filter Axis

The filter axis contains collection of fields that would act as master filter over the data bound in row, column and value axes of the pivot table. The fields along with filter members could be set to filter axis either through report via code behind or by dragging and dropping fields from other axes to filter axis via grouping bar or field list at runtime.

Calculated Field

The calculated field feature allows user to insert or add a new calculated field based on the available fields from the bound data source using basic arithmetic operators. The calculated field can be included in pivot table using the PivotViewCalculatedFieldSetting class from code behind. Or else, calculated fields can be added at run time through the built-in dialog by just setting the AllowCalculatedField property to true in pivot table. You will see a button enabled in the Field List UI automatically to invoke the calculated field dialog and perform necessary operation. To know more about calculated field, refer here.

By default, the calculated fields created through code-behind are only added to the field list and calculated field dialog UI. To display the calculated field in the pivot table UI, it must be added to the PivotViewValues class, as shown in the code below. Additionally, calculated fields can only be added to the value axis.

Handling exceptions

Exceptions occurred during pivot table actions can be handled without stopping application. These error messages or exception details can be acquired using the OnActionFailure event.

The argument passed to the OnActionFailure event contains the error details returned from the server.

NOTE

Recommend you to bind OnActionFailure event during your application development phase, this helps you to find any exceptions. You can pass these exception details to our support team to get solution as early as possible.

The following sample code demonstrates notifying user when server-side exception has occurred during data operation,
