Lot's of new features - virtualization support, frozen columns, API improvements. It is also a completely new development - it does not replace the existing RadzenGrid component.
Differences with the existing RadzenGrid
The API is mostly the same. There are changes in some event arguments and the tag names - RadzenDataGrid and RadzenDataGridColumn vs. RadzenGrid and RadzenGridColumn.
<RadzenGrid TItem="Customer" Data=@customers> <Columns> <RadzenGridColumn TItem="Customer" Property="CustomerName" /> </Columns> </RadzenGrid>
<RadzenDataGrid TItem="Customer" Data=@customers> <Columns> <RadzenDataGridColumn TItem="Customer" Property="CustomerName" /> </Columns> </RadzenDataGrid>
The new RadzenDataGrid utilizes a novel rendering approach that relies on position: sticky to support frozen columns and table headers. Those features are available only on modern browsers though so IE 11 isn't supported.
Availability in Radzen
We plan to integrate RadzenDataGrid in Radzen (in any new applications or new pages created with the CRUD page template).
The fate of the existing RadzenGrid
We will no longer add new features to RadzenGrid - we recommend using RadzenDataGrid for new development. At some point we will deprecate RadzenGrid and probably remove it one of the next major versions.
