        XYDiagram2D diagram = (XYDiagram2D)chart.Diagram;
            if (!diagram.CanZoomIn()) {
                e.Cursor = Cursors.None;
                e.CursorImage = new BitmapImage(new Uri(@"/CustomCursor;component/mycursor.png", UriKind.Relative));
    }
}

VB.NET

Private Sub chartControl1_QueryChartCursor(ByVal sender As Object, ByVal e As QueryChartCursorEventArgs)
    Dim chart As ChartControl = CType(sender, ChartControl)
    Dim diagram As XYDiagram2D = CType(chart.Diagram, XYDiagram2D)
    If Not diagram.CanZoomIn() Then
        e.Cursor = Cursors.None
        e.CursorImage = New BitmapImage(New Uri("/CustomCursor;component/mycursor.png", UriKind.Relative))
    End If
End Sub
