Special Lines

Special Lines are lines that can be drawn at specific times in the GanttChart to indicate milestones, deadlines or other times of interest.

Here is a sample code that will draw a line at a specific time, with the specific color:

this.ganttControl.SpecialLineInfos.Add(new SpecialLineInfo()

{

LineDateTime = TimeComputingUtils.ToUtcKind(DateTime.Today) + TimeSpan.FromDays(10),

ToolTipText = "Deadline",

LineBrush = new SolidColorBrush(Colors.Green)

});

Custom Style

To customize the Style with which the line is rendered, you can create a custom Style like this in your XAML:

First include these namespaces:

<Page ...........

xmlns:srcview="clr-namespace:RadiantQ.Windows.Controls.Gantt.View;assembly=RadiantQ.GanttControls.WPF"

xmlns:converters="clr-namespace:RadiantQ.Windows.Controls.Gantt.ValueConverters;assembly=RadiantQ.GanttControls.WPF"

Then define this Style in your XAML resources section, to change the Width to 3 and use a Background color:

<converters:WidthToLeftMarginConverter x:Key="widthToLeftMarginConverter" />

<Setter.Value>

<Border BorderBrush="{Binding Tag.LineBrush, Mode=OneTime}"

ToolTipService.ToolTip="{Binding Tag.ToolTipText, Mode=OneTime}"

Background="{Binding Tag.LineBrush, Mode=OneTime}"

BorderThickness="1"

Width="3"

Grid.Row="0"

Grid.Column="0"

HorizontalAlignment="Left"

Margin="{Binding Width, Converter={StaticResource widthToLeftMarginConverter}}">

</Border>

</DataTemplate>

</Setter.Value>

</Setter>

</Style>
