PivotItemFormatRule Class

A format rule used to apply conditional formatting to the Pivot dashboard item.

Namespace: DevExpress.DashboardCommon

Assembly: DevExpress.Dashboard.v24.2.Core.dll

Declaration

C#

public class PivotItemFormatRule :
    CellsItemFormatRule,
    IFormatRuleIntersectionLevel,
    IFormatRuleLevel

VB.NET

Public Class PivotItemFormatRule
    Inherits CellsItemFormatRule
    Implements IFormatRuleIntersectionLevel,
               IFormatRuleLevel

Remarks

The Pivot dashboard item allows you to apply conditional formatting to data cells or field value cells. The PivotDashboardItem.FormatRules property provides access to a collection of the PivotItemFormatRule objects that are used to define formatting settings.

To add a new format rule, create the PivotItemFormatRule object and specify the following settings.

• Create a required condition (the FormatConditionBase descendant), specify its settings and assign the resulting object to the DashboardItemFormatRule.Condition property.
• Set a measure/dimension whose values are checked using the specified condition by specifying the CellsItemFormatRule.DataItem property. The CellsItemFormatRule.DataItemApplyTo property specifies the measure/dimension to whose values a formatting should be applied.
• Specify the intersection level used to apply formatting using the PivotItemFormatRule.IntersectionLevelMode property. If the PivotItemFormatRule.IntersectionLevelMode property is set to FormatConditionIntersectionLevelMode.SpecificLevel, specify the intersection level manually using the PivotItemFormatRule.Level property.
• Optionally, enable the CellsItemFormatRule.ApplyToRow/PivotItemFormatRule.ApplyToColumn flags to apply formatting to the entire pivot row/column.

Finally, add the created format rule to the GridDashboardItem.FormatRules collection. You can use the DashboardItemFormatRule.Enabled property to specify whether the current format rule is enabled.

Example

The following example demonstrates how to apply conditional formatting to Pivot cells at different detail levels.

• The Value format condition (FormatConditionValue) is used to apply formatting to the first-level data cells.
• The Range Gradient condition (FormatConditionRangeGradient) is used to highlight the last-level data cells
• The Color Range condition (FormatConditionRangeSet) is used to classify values of Grand Total cells.
• The Top-Bottom condition (FormatConditionTopBottom) highlights row field values corresponding to top 3 categories.
