Lists values that specify the type of a PivotGridControl’s item to be represented in a ChartControl.
Namespace : DevExpress.XtraPivotGrid
Assembly : DevExpress.PivotGrid.v25.2.Core.dll
NuGet Packages : DevExpress.PivotGrid.Core, DevExpress.Win.Navigation
public enum PivotChartItemType
Public Enum PivotChartItemType
| Name | Description |
|---|---|
RowItem |
A row field value is processed to be represented in the chart control.
|
| ColumnItem |
A column field value is processed to be represented in the chart control.
|
| CellItem |
A data cell value is processed to be represented in the chart control.
|
The following properties accept/return PivotChartItemType values:
| Library | Related API Members |
|---|---|
| WinForms Controls | PivotCustomChartDataSourceDataEventArgs.ItemType |
| ASP.NET Web Forms Controls | PivotCustomChartDataSourceDataEventArgs.ItemType |
Values listed by this enumeration are used to set the ItemType property of the CustomChartDataSourceData event’s parameter (the PivotCustomChartDataSourceDataEventArgs.ItemType property for the XtraPivotGrid, and the PivotCustomChartDataSourceDataEventArgs.ItemType property for the ASPxPivotGrid).
The following example demonstrates how to add custom text to data prepared by the PivotGridControl, to display it in a ChartControl.
For this, it is necessary to handle the PivotGridControl.CustomChartDataSourceData event. In this event handler, you can determine the item type via the PivotCustomChartDataSourceDataEventArgs.ItemType property and change the PivotCustomChartDataSourceDataEventArgs.Value according to your custom requirements.
