This sample demonstrates the Tree Grid event model with a live Event Trace panel that captures lifecycle, action, and interaction events to support customization and troubleshooting.
Wire events by adding the TreeGridEvents component and handling lifecycle/user interaction events. The Event Trace panel updates in real time during paging, sorting, reordering, editing, row expand/collapse, and selection. These features are enabled by setting AllowPaging, AllowSorting, AllowReordering, and AllowSelection to true.
More information on events can be found in the documentation section.
