This page demonstrates how to use templates to create a Radzen Blazor DataGrid hierarchy.
In this demo a 4-level hierarchy shows Customers → Orders (with tabs) → Order Details → Employee Territories. You can toggle ExpandMode between Single/Multiple and use buttons to expand/collapse all rows on the current page.
