    ConstantLine constantLine = new ConstantLine();
    constantLine.AxisValue = 65.0;
    constantLine.Title.Text = "Title";    
    constantLine.RuntimeTitleEditing = true;
    constantLine.RuntimeMoving = true;

    XYDiagram diagram = chartControl1.Diagram as XYDiagram;
    diagram.AxisY.ConstantLines.Add(constantLine);

    chartControl1.ConstantLineMoved += OnChartControlConstantLineMoved;
}

private void OnChartControlConstantLineMoved(object sender, ConstantLineMovedEventArgs e) {
    e.ConstantLine.Title.Text = String.Format("{0:f3}",e.ConstantLine.AxisValue);
}

VB.NET

Private Sub OnFormLoad(ByVal sender As Object, ByVal e As EventArgs)

    Dim constantLine As ConstantLine = New ConstantLine()
    constantLine.AxisValue = 65.0
    constantLine.Title.Text = "Title"
    constantLine.RuntimeTitleEditing = True
    constantLine.RuntimeMoving = True

    Dim diagram As XYDiagram = TryCast(chartControl1.Diagram, XYDiagram)
    diagram.AxisY.ConstantLines.Add(constantLine)

    chartControl1.ConstantLineMoved += AddressOf OnChartControlConstantLineMoved
End Sub

Private Sub OnChartControlConstantLineMoved(ByVal sender As Object, ByVal e As ConstantLineMovedEventArgs)
    e.ConstantLine.Title.Text = String.Format("{0:f3}", e.ConstantLine.AxisValue)
