Class RadzenDataGrid<TItem>

A powerful data grid component for displaying and manipulating tabular data with support for sorting, filtering, paging, grouping, editing, and selection. RadzenDataGrid provides a full-featured table with inline editing, master-detail views, virtualization, export capabilities, and extensive customization options. Supports single/multiple column sorting, simple/advanced filtering, grouping with aggregation, inline/cell editing with validation, and single/multiple row selection with checkbox columns. Features on-demand data loading via LoadData event for server-side operations, export to Excel and CSV formats, column/row templates, group headers/footers, and density modes (Default/Compact) for responsive layouts. The grid can work with in-memory collections or load data on-demand from APIs. Columns are defined using RadzenDataGridColumn components within the Columns template.
