Detail rows are always hidden. Users cannot expand these rows.


Detail rows display preview sections under each Grid data row across all columns. These sections can display any content, including tables, values from data source fields, custom text, etc. Users cannot collapse detail rows.


The Grid allows users to create master-detail layouts of any complexity. To enable this functionality, specify the DetailRowTemplate.

Use the DetailRowDisplayMode property to specify when to display detail rows in the Grid. The default property value is Auto. The Grid shows detail rows if the corresponding master rows are expanded. Otherwise, detail rows are hidden.
