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

Property Description

Examples

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.

using System;
using System.Windows.Forms;
using DevExpress.XtraCharts;
// ...
private void chartControl1_QueryCursor(object sender, QueryCursorEventArgs e) {
    if (e.CursorType == CursorType.Hand || e.CursorType == CursorType.Grab) {
        e.Cursor = Cursors.Default;
    }
}
