ChartControl.QueryCursor Event

Occurs when there is a request to display the cursor.

Namespace: DevExpress.XtraCharts

Assembly: DevExpress.XtraCharts.v19.2.UI.dll

Declaration

C#

public event QueryCursorEventHandler QueryCursor

VB.NET

Public Event QueryCursor As QueryCursorEventHandler

Event Data

The QueryCursor event's data class is QueryCursorEventArgs. The following properties provide information specific to this event:

Property	Description
Cursor	Gets or sets the mouse cursor currently being shown for the chart.
CursorType	Gets the cursor type.

Remarks

In the QueryCursor event handler, you can provide custom cursors for your chart in various circumstances (e.g. when a chart is being scrolled or zoomed).

Example

This example demonstrates how to substitute the Hand and Grab cursors shown when a chart’s area is being scrolled with a default system cursor.

To do this, handle the ChartControl.QueryCursor event, and use the QueryCursorEventArgs.Cursor and QueryCursorEventArgs.CursorType properties.
