The DevExpress Blazor TreeList allows you to display values not stored in the assigned data source (using unbound columns). This demo includes two unbound columns:

  • Q2 Sales — Values are calculated based on data in other columns and the use of UnboundExpression.
  • Q2 YoY Change (%) — Values are calculated in the UnboundColumnData event handler.

Note: Unbound columns must use FieldName values that have no matching field name values in the TreeList data source.
