Gantt Data Binding to Hierarchical Data
Updated on Oct 1, 2026
This article explains how to bind the Gantt Chart for Blazor to hierarchical data.
Hierarchical data means that the collection of child items is provided in a field of its parent's model. By default, this is the Items field, and hierarchical data binding is the default mode of the Gantt Tree. This approach of providing items lets you gather separate collections of data that may even come from different sources.
If there are items for a certain node, it will have an expand icon. The HasChildren field can override this, however, but it is not required for hierarchical data binding.
