DxPivotGrid<T> Class

An Excel-inspired pivot table component engineered for multi-dimensional data analysis and cross-tab reporting.

Assembly : DevExpress.Blazor.v25.2.dll

Declaration

csharp

public class DxPivotGrid<T> :
    DxPivotGrid

Type Parameters

Name	Description
T

The data item type.

Remarks

Important

The Pivot Grid was moved to maintenance support mode. No new features/capabilities will be added to this component. We recommend that you migrate to the Pivot Table component.

The DevExpress Pivot Grid for Blazor (<DxPivotGrid>) allows you to display and analyze multi-dimensional data from the underlying data source. Use this component to calculate summaries and totals against individual values and display the results within the pivot table’s cells.

Add a Pivot Grid to a Project

Follow the steps below to add the Pivot Grid component to an application:

Create a Blazor Server or Blazor WebAssembly application.
Add the <DxPivotGrid>…</DxPivotGrid> markup to a .razor file.
Bind the Pivot Grid to a strongly-typed data collection.
Specify fields that supply data to columns, rows, and data cells.
Specify other Pivot Grid options (see the sections below).

API Reference

Refer to the following list for the component API reference: DxPivotGrid Members.

Bind to Data

Use the Data property to bind <DxPivotGrid> to a strongly-typed collection.

Note

The Pivot Grid operates in bound mode only. Unbound mode is not supported.

Fields

The Pivot Grid fields supply data to <DxPivotGrid> columns, rows, and data cells. The DxPivotGridField class defines a field.

razor

<DxPivotGrid Data="@GridData">
    <DxPivotGridField Field="@nameof(SaleInfo.Date)" Area="PivotGridFieldArea.Column"></DxPivotGridField>
    ...
</DxPivotGrid>

Use the field’s Area property to specify the field location: Column Header Area , Row Header Area , or Data Header Area.

Column Header Area contains fields that define grid columns.
Row Header Area contains fields that define grid rows.
Data Header Area contain fields that store data for grid cells.

Note

To hide field headers, set the ShowFieldHeaders property to false.

Cells

Pivot Grid cells display summaries calculated against data fields. The SummaryType property specifies the field’s summary type.

razor

<DxPivotGridField Field="@nameof(SaleInfo.OrderId)"
                  Area="PivotGridFieldArea.Data"
                  Caption="Count"
                  SummaryType="PivotGridSummaryType.Count" />

The available summary types are:

Summary Type	Description
Sum
(the default type)	The sum of the field values. This type applies to numeric fields only.

Avg	The average of the field values. This type applies to numeric fields only.

Count	The total number of field values.
Max	The largest field value.
Min	The smallest field value.

Totals

DxPivotGrid calculates totals and displays them as separate columns and rows. Totals use the corresponding data field’s summary type for calculations.

The Pivot Grid component supports the following totals:

Row/column totals display sub-totals calculated for outer row/column fields.
Row/column grand totals display summary totals calculated against all the rows/columns. To hide grand totals, set the ShowGrandTotals property to false.

Sort Data

DxPivotGrid data is always sorted by row and column fields. A field header displays a sort order (ascending or descending) for the corresponding field’s values. To change the sort order, use the SortOrder property in code or click the field header at runtime.

razor

<DxPivotGridField Field="@nameof(SaleInfo.Region)" SortOrder="SortOrder.Ascending"></DxPivotGridField>

Group Data

You can group grid data by date/time field values. To specify how field values are grouped, use the GroupInterval property.

razor

<DxPivotGrid Data="@GridData">
    <DxPivotGridField Field="@nameof(SaleInfo.Date)"
                      Area="PivotGridFieldArea.Column"
                      GroupInterval="PivotGridGroupInterval.Year"
                      Caption="Year">
    </DxPivotGridField>
    <DxPivotGridField Field="@nameof(SaleInfo.Date)"
                      Area="PivotGridFieldArea.Column"
                      GroupInterval="PivotGridGroupInterval.Quarter"
                      Caption="Quarter">
        <HeaderTemplate>@string.Format("Q{0}", context)</HeaderTemplate>
    </DxPivotGridField>
</DxPivotGrid>

The image below displays DxPivotGrid in two states:

The Date field contains original data.
The Date field is grouped by years and quarters.

Visualize Data

Do the following to link <DxPivotGrid> with the DxChart<T> component:

Create a method that asynchronously loads data from an IEnumerable<T> data source (Sales.Load() in this example).
Create a DxPivotGridDataProvider<T> object based on the created method.
Bind the Chart to the provider object. Use the ChartDataSource property.
Bind the Pivot Grid to the provider object. Use the PivotGridDataSource property.

razor

<DxChart Data="@(PivotGridDataProvider.ChartDataSource)">
    <DxChartCommonSeries NameField="@((IChartDataItem s) => s.SeriesName)"
                         ArgumentField="@(s => s.Argument)"
                         ValueField="@(s => s.Value)"
                         SeriesType="ChartSeriesType.Bar" />
</DxChart>

<DxPivotGrid Data="@(PivotGridDataProvider.PivotGridDataSource)">
    <DxPivotGridField Field="@nameof(SaleInfo.Region)" SortOrder="PivotGridSortOrder.Ascending" 
        Area="PivotGridFieldArea.Row"></DxPivotGridField>
    <DxPivotGridField Field="@nameof(SaleInfo.Country)" Area="PivotGridFieldArea.Row"></DxPivotGridField>
    <DxPivotGridField Field="@nameof(SaleInfo.City)" Area="PivotGridFieldArea.Row"></DxPivotGridField>
    <DxPivotGridField Field="@nameof(SaleInfo.Date)" GroupInterval="PivotGridGroupInterval.Year" 
        Area="PivotGridFieldArea.Column" Caption="Year"> </DxPivotGridField>
    <DxPivotGridField Field="@nameof(SaleInfo.OrderId)" Caption="Count" Area="PivotGridFieldArea.Data" 
        SummaryType="PivotGridSummaryType.Count"> </DxPivotGridField>
</DxPivotGrid>

@code {
    DxPivotGridDataProvider<SaleInfo> PivotGridDataProvider = DxPivotGridDataProvider<SaleInfo>.Create(Sales.Load());
}

The Chart shows data from the Pivot Grid’s lowest expanded level. The Chart is updated when a user expands or collapses rows/columns in the Pivot Grid.

Paging

Use the PageSize property to specify the maximum number of rows a page can display.

To hide the pager, set the ShowPager property to false.

Templates

To define a completely different look and feel of row/column field headers and data cells, use templates: HeaderTemplate and DataTemplate.

razor

<DxPivotGrid Data="@GridData" ShowGrandTotals="@ShowGrandTotals" ShowFieldHeaders="@ShowFieldHeaders">
    <DxPivotGridField Field="@nameof(SaleInfo.Date)" GroupInterval="PivotGridGroupInterval.Month" Area="PivotGridFieldArea.Column" Caption="Month">
        <HeaderTemplate>
            @System.Globalization.CultureInfo.CurrentCulture.DateTimeFormat.GetMonthName((int)context)
        </HeaderTemplate>
    </DxPivotGridField>
    <DxPivotGridField Field="@nameof(SaleInfo.Amount)" Area="PivotGridFieldArea.Data" SummaryType="PivotGridSummaryType.Sum">

        <DataTemplate>
            <span class="@((decimal)context > 100000 ? "text-success" : "text-danger")">
                @string.Format("{0:c0}", context)
            </span>
        </DataTemplate>
    </DxPivotGridField>
</DxPivotGrid>
