NuGet Package: DevExpress.WinUI

C#

[DP(null, Handler = "InvalidateLayout")]
public object DonutGroup { get; set; }

<DP(Nothing, Handler:="InvalidateLayout")>
Public Property DonutGroup As Object

Property Value

Type	Description
Object	An integer that specifies the donut group index.

Remarks

Enable the PieSeriesView.ShowDonut property to show the pie series as a donut.

Multiple donuts are displayed nested if they have the same PieSeriesView.DonutGroup property value. Specify the PieSeriesView.DonutGroupInnerIndent property to define the gap between two nested donuts. To control the thickness of donuts, specify the PieSeriesView.DonutGroupWeight property.

The following markup adds two donut series, and displays the second series as a nested donut:
