Milestone Customization using TaskColorsBinding

The TaskColorsBinding property in the GanttControl discussed earlier can also be used to customize the look and feel of a Milestone type task (with Effort = 0).

To begin with set the above property with a Converter:

this.ganttControl.TaskColorsBinding = new Binding("DataSource.SomeProperty") { Converter = new CustomTaskColorProvider() };

Then in the converter, specify a custom shape and color for the Milestone:

public class CustomTaskColorProvider : IValueConverter

{

#region IValueConverter Members

public object Convert(object value, Type targetType, object parameter, System.Globalization.CultureInfo culture)

{

IActivity activity = parameter as IActivity;

SomeType someTypeValue = value as SomeType;

YourBoundTaskType task = ((DataBoundActivity)activity).DataSource as YourBoundTaskType;

if (task.Effort == TimeSpan.Zero)

{

PointCollection pc = new PointCollection();

LinearGradientBrush barFillBrush = null;

SolidColorBrush barStrokeBrush = null;

// Fill the above based on activity, task and someTypeValue.
return new TaskSpecificLook()

{

MilestonePoints = pc,

TaskItemBarFill = barFillBrush,

TaskItemBarStroke = barStrokeBrush

// Other customization options:

//TaskItemProgressFill = brush3,

};

}

else

return null;

}

Please take a look at the "ProjectGantt\Appearance\GanttControlCustomAppearance" sample where this is fully illustrated.
