The code below shows how to make dependency lines twice as wide.

C#

using DevExpress.XtraGantt;

private void ganttControl1_CustomDrawTaskDependency(object sender, CustomDrawTaskDependencyEventArgs e) {
    for (int i = 0; i < e.Lines.Count; i++) {
        var line = e.Lines[i];
        if (line.Width == 1)
            line.Width = 2;
        if (line.Height == 1)
            line.Height = 2;
        e.Lines[i] = line;
    }
}

VB.NET

Imports DevExpress.XtraGantt

Private Sub ganttControl1_CustomDrawTaskDependency(ByVal sender As Object, ByVal e As CustomDrawTaskDependencyEventArgs) _
    Handles ganttControl1.CustomDrawTaskDependency
    For i As Integer = 0 To e.Lines.Count - 1
        Dim line = e.Lines(i)
        If line.Width = 1 Then
            line.Width = 2
        End If
        If line.Height = 1 Then
            line.Height = 2
        End If
        e.Lines(i) = line
    Next i
End Sub
