Provides an image for the custom cursor.

Namespace: DevExpress.Xpf.Charts

Assembly: DevExpress.Xpf.Charts.v24.1.dll

NuGet Package: DevExpress.Wpf.Charts

Declaration

C#

public ImageSource CursorImage { get; set; }

VB.NET

Public Property CursorImage As ImageSource

Property Value

Type	Description
ImageSource	A ImageSource object

Remarks

Use the CursorImage property to specify the appearance for a custom cursor.

Example

This example shows how to display a custom cursor when the mouse pointer is hovering over the chart control.

To accomplish this task, handle the ChartControl.QueryChartCursor event and assign your custom image (e.g., a BitmapImage object loaded from application resources) to the QueryChartCursorEventArgs.CursorImage property.

Note that you need to include your image in the project and set the QueryChartCursorEventArgs.Cursor property to None to see the custom image in the chart control.
