Class SfPivotFieldList<TValue>

The Blazor Pivot Field List component allows to add or remove fields and also rearrange them between different axes, including column, row, value, and filter along with sort and filter options dynamically at runtime. It can be displayed in two different formats either in-built (Popup) or stand-alone (Fixed) field list to interact with pivot table.

These aggregate options help to display the values in the pivot table with appropriate aggregations such as sum, product, count, average, etc… easily at runtime. The available aggregate options are: Sum: Allows to display the pivot table values with sum. Product: Allows to display the pivot table values with product. Count: Allows to display the pivot table values with count. DistinctCount: Allows to display the pivot table values with distinct count. Min: Allows to display the pivot table with minimum value. Max: Allows to display the pivot table with maximum value. Avg: Allows to display the pivot table values with average. Index: Allows to display the pivot table values with index. PopulationStDev: Allows to display the pivot table values with population standard deviation. SampleStDev: Allows to display the pivot table values with sample standard deviation. PopulationVar: Allows to display the pivot table values with population variance. SampleVar: Allows to display the pivot table values with sample variance. RunningTotals: Allows to display the pivot table values with running totals. DifferenceFrom: Allows to display the pivot table values with difference from the value of the base item in the base field. PercentageOfDifferenceFrom: Allows to display the pivot table values with percentage difference from the value of the base item in the base field. PercentageOfGrandTotal: Allows to display the pivot table values with percentage of grand total of all values. PercentageOfColumnTotal: Allows to display the pivot table values in each column with percentage of total values for the column.

Declaration
public List<AggregateTypes> AggregateTypes { get; set; }
Property Value
Type Description
System.Collections.Generic.List<AggregateTypes>

AllowCalculatedField

Allows the built-in calculated field dialog to be displayed in the component. You can view the calculated field dialog by clicking the "Calculated Field" button in the field list UI. This dialog will helps you to create a new calculated field in the pivot table, based on available fields from the bound data source or using simple formula with basic arithmetic operators at runtime.

Declaration
public bool AllowCalculatedField { get; set; }
Property Value
Type Description
System.Boolean

AllowDeferLayoutUpdate

Allows the pivot table component to be updated only on demand, meaning, you can perform a variety of operations such as drag-and-drop fields between row, column, value and filter axes, apply sorting and filtering inside the Field List, resulting the field list UI would be updated on its own, but not the pivot table. On clicking the “Apply” button in the Field List, the pivot table will updates the last modified report. This helps to improve the performance of the pivot table component rendering.

Declaration
public bool AllowDeferLayoutUpdate { get; set; }
Property Value
Type Description
System.Boolean

You can fill empty value cells with any value like “0”, ”-”, ””, “(blank)”, etc. groupSettings: Allows specific fields to group their data on the basis of their type. For example, the date type fields can be formatted and displayed based on year, quarter, month, and more. Likewise, the number type fields can be grouped range-wise, such as 1-5, 6-10, etc. You can perform custom group to the string type fields that used to displayed in the pivot table. authentication: Allows you to set the credential information to access the specified SSAS cube.
