FormatConditionDateOccurring Class

A format condition used to apply formatting to date-time values concerning a specific date and/or date interval relative to today.

Namespace: DevExpress.DashboardCommon

Assembly: DevExpress.Dashboard.v24.1.Core.dll

NuGet Package: DevExpress.Dashboard.Core

Declaration

C#

public class FormatConditionDateOccurring :
    FormatConditionStyleBase

VB.NET

Public Class FormatConditionDateOccurring
    Inherits FormatConditionStyleBase

Remarks

To create a format condition to apply formatting to the required date-time values, do the following.

• Specify a filter that identifies specific dates or date intervals using the FormatConditionDateOccurring.DateType property.
• Specify the required style settings applied to target elements using the FormatConditionStyleBase.StyleSettings property. You can change the color of dashboard item elements, font settings (AppearanceSettings) or add predefined icons (IconSettings).

Assign the resulting FormatConditionDateOccurring object to the DashboardItemFormatRule.Condition property.

Example

The Date Occurring format condition (FormatConditionDateOccurring) allows you to apply formatting to date-time values of a specific date and/or date interval relative to today.

This example demonstrates how to apply conditional formatting to Grid cells whose values fall into one of the predefined intervals.
