## Content



A milestone is a significant point or landmark in your project. Milestones are created as tasks with zero duration and are visualized with diamond shape. The milestone’s shape and color are customizable. Additionally, text can appear to the left, right, top, or bottom of the milestone marker. To create a milestone, you can use the **Duration** property of the **Task** class and set its value to zero.

To create a milestone at design time, follow the steps below:

1.  Select the **GanttView** control and click on its smart tag to open the **C1GanttView Tasks menu**.
2.  Select Edit Tasks. The **C1GanttView.Tasks Collection Editor** appears.
3.  Click Add to add a task to the Members list.
4.  Enter the **Name**, **Start** date and **Finish** date for the task.
5.  Set the **Duration** to 0.
