GridItemFormatRule Class

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

Namespace: DevExpress.DashboardCommon

Assembly: DevExpress.Dashboard.v19.1.Core.dll

Declaration

C#

public class GridItemFormatRule :
    CellsItemFormatRule

VB.NET

Public Class GridItemFormatRule
    Inherits CellsItemFormatRule

Remarks

The Grid dashboard item allows you to apply conditional formatting to cells. The GridDashboardItem.FormatRules property provides access to a collection of the GridItemFormatRule objects that are used to define formatting settings.

To add a new format rule, create the GridItemFormatRule 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.
• Optionally, enable the CellsItemFormatRule.ApplyToRow flag to apply formatting to the entire grid row.

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 Value format condition (FormatConditionValue) allows you to compare dimension/measure values with predefined static values.

This example demonstrates how to apply conditional formatting to Grid cells whose values are greater than, less than or between the specified values.
