Remarks

The ChartControl.QueryChartCursor event occurs when there is a request to display the cursor.

The QueryChartCursorEventArgs class introduces the QueryChartCursorEventArgs.Cursor and QueryChartCursorEventArgs.CursorImage properties, which allow you to provide custom cursors for your chart.

Note that QueryChartCursorEventArgs objects are automatically created, initialized and passed to ChartControl.QueryChartCursor event handlers.

Examples

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.
