Since the AnchorBottom property of Line control is used for vertical lines,

the bottom horizontal line can be set for section with dynamic height at run-time only.

The following sample of code shows how section height can be used

in Before Print event for change of line control location:

[VB.NET]

    Private Sub Detail1_BeforePrint()

        Me.Line1.Y1 = Me.Detail1.Height - 0.01

        Me.Line1.Y2 = Me.Line1.Y1

    End Sub

[C#]

private void Detail1_BeforePrint()

{

Line1.Y1 = Detail1.Height - 0.01f;

Line1.Y2 = Line1.Y1;
