SharePoint Timeline Rollup

The Lightning Conductor v4 has just been released for SharePoint 2013, SharePoint 2016 and SharePoint Online and now includes a SharePoint Timeline Rollup View for Task Lists! The SharePoint Timeline View makes it possible to use more than one single Task list as the source of a Timeline view which is the current capability of the SharePoint Timeline Web Part that comes out-of-the-box.

The Lightning Conductor ships with several built in views included that can be displayed within the Lightning Conductor meaning that you don’t need to purchase more than one web part to build your desired solution.

SharePoint Tasks Rollup in a Calendar View

Using the Lightning Conductor you could go on to display your tasks in other formats too such as a Calendar View and a Grid View. The Lightning Conductor Calendar View is built into the Lightning Conductor and therefore does not require an additional purchase. The Calendar view provides a great way of viewing the tasks that you or your SharePoint Team need to complete by day, week, or month view.

To display your tasks in a calendar view, follow these steps:

1. Create another new view within the same web part instance.

Display Tasks in a Grid View

Using the multiple grouping option, you could group by Task Priority and also Task Status. To build a Tasks view using the SPGridView option:

1. Click Create View to create your third view.

Display Your Tasks in a Chart

If the above three views don’t provide what you are looking for, you could also consider displaying your tasks in a drill down SharePoint Chart using the Lightning Conductor Chart Web Part. The Lightning Conductor and the SharePoint Chart web part come as a bundle and can be connected to each other to display really powerful Task views.
