GraphicalView Link Item Formatting
RadGanttView allows formatting of individual links through the GraphicalViewLinkItemFormatting event. The following example demonstrates how to format links based on their type.
private void radGanttView1_GraphicalViewLinkItemFormatting(object sender, GanttViewLinkItemFormattingEventArgs e)
{
Color color = Color.Black;
DashStyle dash = DashStyle.Solid;
switch (e.Link.LinkType)
{
case TasksLinkType.FinishToFinish:
dash = DashStyle.DashDotDot;
color = Color.Red;
break;
case TasksLinkType.FinishToStart:
dash = DashStyle.Dash;
color = Color.Green;
break;
case TasksLinkType.StartToFinish:
dash = DashStyle.DashDot;
color = Color.Blue;
break;
case TasksLinkType.StartToStart:
dash = DashStyle.Dot;
color = Color.Black;
break;
}
Pen pen = new Pen(color);
pen.DashStyle = dash;
pen.Width = 3;
pen.LineJoin = LineJoin.Bevel;
pen.EndCap = LineCap.ArrowAnchor;
e.Pen = pen;
}
Private Sub RadGanttView1_GraphicalViewLinkItemFormatting(sender As Object, e As Telerik.WinControls.UI.GanttViewLinkItemFormattingEventArgs)
Dim penColor As Color = Color.Black
Dim dash As DashStyle = DashStyle.Solid
Select Case e.Link.LinkType
