GanttView for WinForms allows you to split tasks into several parts to determine times of work and suspensions. You can move the separated parts of a task, increase and decrease period of work/suspension on chart view using mouse. You can also split the selected task from the context menu by clicking Split task menu item. If you need to put a task on hold in the middle, you can easily split the task so that a part of it can be started later. You can also split a task as many times as you need.

Split task feature can be used in situations where a resource already working on a task goes on a leave or is assigned another task on high priority. In the latter case, the resource might need to put the currently assigned task on hold to start the newly assigned task. In this situation, the ongoing task can be split into two parts so that the newly assigned high priority task can be started. The resource can resume the interrupted task again as soon as the high priority task gets completed.
