Syntax

public class SfPivotFieldList<TValue> : SfDataBoundComponent, IPivotFieldList, ISfCircularComponent

Type Parameters

Name	Description

Constructors

SfPivotFieldList()

Declaration

public SfPivotFieldList()

Properties

AggregateTypes

Allows you to show a menu with built-in aggregate options displayed in the pivot button's dropdown icon of fieldList UI. 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.

Declaration

public List<AggregateTypes> AggregateTypes { get; set; }

Property Value

Type	Description
System.Collections.Generic.List<AggregateTypes>	A list of AggregateTypes instances.

AllowCalculatedField

Gets or sets a value indicating whether the built-in calculated field dialog can be displayed in the component.

Declaration

public bool AllowCalculatedField { get; set; }

Property Value

Type	Description
System.Boolean	`true`, if the calculated field dialog can be enabled. Otherwise, `false`.

Remarks

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.

AllowDeferLayoutUpdate

Gets or sets a value indicating whether the pivot table component should be updated only on demand. This means that 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	`true`, if the defer layout update option can be enabled. Otherwise, `false`.

CssClass

Allows you to add the CSS class name to the field list element. Use this class name, you can customize the field list easily at your end.

Declaration

public string CssClass { get; set; }

Property Value

Type	Description
System.String	Accepts the string value.

DataSourceSettings

Gets or sets the following pivot report information such as rows, columns, values, filters, etc., that are used to render the pivot table and field list.

Declaration

public IPivotFieldListDataSourceSettings DataSourceSettings { get; set; }

Property Value

Type	Description
IPivotFieldListDataSourceSettings	An instance of IPivotFieldListDataSourceSettings

ElementAttributes

Catches unmatched attributes from the component. This can be used to specify custom style, class and other attributes to the pivot table.

Declaration

public IDictionary<string, object> ElementAttributes { get; set; }

Property Value

Type
System.Collections.Generic.IDictionary<System.String, System.Object>

EnablePersistence

Gets or sets a value that indicates whether to enable or disable persisting component's state between page reloads.

Declaration

public bool EnablePersistence { get; set; }

Property Value

Type	Description
System.Boolean	`true`, if the persistence can be enabled. Otherwise, `false`.

EnableRtl

Enable or disable rendering component in right to left direction.

Declaration

public bool EnableRtl { get; set; }

Property Value

Type	Description
System.Boolean	`true`, if the right to left direction can be enabled for the component. Otherwise, `false`. The default value is `false`.

ID

Declaration

public string ID { get; set; }

Property Value

Type	Description
System.String	Accepts the string value.

ijsRuntime

Declaration

protected IJSRuntime ijsRuntime { get; set; }

Property Value

Type
Microsoft.JSInterop.IJSRuntime

LoadOnDemandInMemberEditor

Gets or sets a boolean value indicating whether to load members inside the member filter dialog on-demand. The first level members will be loaded from the OLAP cube to display the member editor by default. As a result, the member editor will open quickly without any performance constraints.

Declaration

public bool LoadOnDemandInMemberEditor { get; set; }

Property Value

Type	Description
System.Boolean	`true`, allows to load members inside the member filter dialog on-demand. Otherwise, `false`. The default value is `true`.

Remarks

You can use either of the following actions to load your next level members. The actions are:

By clicking on the respective member's expander button. By doing so, only the child members of the respective member will be loaded.
By choosing the level from the drop-down button. By doing so, all the members up to the level chosen will be loaded from the cube.

MaxNodeLimitInMemberEditor

Gets or sets the limit for displaying members while loading large data in the member filter dialog. Based on this limit, initial loading will be completed quickly without any performance constraint. A message with remaining member count, that are not currently shown in the member filter dialog UI, will be displayed in the member editor.

Declaration

public int MaxNodeLimitInMemberEditor { get; set; }

Property Value

Type	Description
System.Int32	Accepts an integer value. The default value is `1000`.

Remarks

This property is not applicable to user-defined hierarchies in the OLAP data source.

RenderMode

Gets or sets the render mode to display the field list either in Fixed or Popup mode.

Declaration

public Mode RenderMode { get; set; }

Property Value

Type	Description
Mode	The default value is Popup.

Remarks

The available modes are: Popup: To display the field list icon in pivot table UI to invoke the built-in dialog. It helps to display over the pivot table UI without affecting any form of UI shrink within a web page.

Declaration

public bool ShowFieldSearch { get; set; }

Property Value

Type	Description
System.Boolean	`true` if the field search bar is enabled; otherwise, `false`.

Remarks

Use this property to control the visibility of the field search bar in the field list. When set to true, the field search bar will be shown, allowing users to search for fields. When set to false, the field search bar will be hidden.

ShowValuesButton

Gets or sets a value indicating whether to create a pivot button with "Values" as a caption. This pivot button is displayed in the grouping bar and field list UI. It helps you to plot the value fields to either column or row axis during runtime.

Declaration

public bool ShowValuesButton { get; set; }

Property Value

Type	Description
System.Boolean	`true`, if the pivot values button should be shown. Otherwise, `false`.

Remarks

The ShowValuesButton property is enabled by default for the OLAP data source. And the pivot button can be displayed with "Measures" as a caption used to display in the grouping bar and field list UI.

Target

Gets or sets the specific target element for the field list dialog. This helps the field list dialog to display the appropriate position on its target element.

Declaration

public string Target { get; set; }

Property Value

Type	Description
System.String	Accepts an string value.

Remarks

To use this option, set the property RenderMode to be Popup.

OnInitializedAsync()

Method invoked when the component is ready to start, having received its initial parameters from its parent in the render tree. Override this method if you will perform an asynchronous operation and want the component to refresh when that operation is completed.

Declaration

protected override Task OnInitializedAsync()

Returns

Type	Description
System.Threading.Tasks.Task	A System.Threading.Tasks.Task representing any asynchronous operation.

Overrides

SfDataBoundComponent.OnInitializedAsync()

OnParametersSetAsync()

ResetPersistDataAsync()

Resets the state of the pivot table.

Declaration

public Task ResetPersistDataAsync()

Returns

Type	Description
System.Threading.Tasks.Task	void.

Remarks

ShowFieldListDialogAsync()

This method opens the field list dialog programmatically. You can use this dialog to add or remove fields, as well as rearrange them between different axes, such as column, row, value, and filter, as well as sort and filter options dynamically at runtime. In addition, by enabling the AllowDeferLayoutUpdate property, you can perform all UI actions within the field list UI, resulting in a change in the pivot report but not in the pivot table UI. When you click the "Apply" button in the field list UI, the pivot table will begin to update with the most recently modified report. This improves better performance in pivot table component rendering.

This option is only available when the RenderMode property is set to Mode.Popup.

Declaration

public Task ShowFieldListDialogAsync()

Returns

Type	Description
System.Threading.Tasks.Task	void.
