The DevExpress ASP.NET Tree List (ASPxTreeList) provides a set of templates that allow you to create custom layouts for its visual elements (column headers, data and footer cells, etc.).
This demo shows how to use data cell templates to create a card view layout within nodes.
The Eval function is used to define one-way (read-only) binding. The Eval method takes the name of a data field, and returns an object containing the value of that field from the current record in the data source.
You can also use Template Containers to obtain cell values, display text, etc.
