Remarks

WebGrid.NET v5.0 maintain the capability to display expandable preview row, much like in Outlook® auto preview mode. There are numerous settings related to preview row feature such as you can customize its style, change the expander image or have it expanded by default.

PreviewRow settings is attached per table and can be found in expandable PreviewRowSettings property. Note that it is possible to enable previewrow mode along with columnset mode, as well as with other existing features such as grouping, hierarchical and dozens of UI settings' combinations.

The list of PreviewRowSettings includes:

DataMember
The data field that will be displayed in preview row. (required)
DefaultExpanded
Specifies whether the preview row should be expanded by default. Default value: True
Expandable
Specifies whether the preview row is expandable. When set to False, PreviewRow Expander Column will not appear and DefaultExpanded must be set to True. Default value is True.
Height
Specifies the height of preview row. Default is Empty, means that the height will follow the text's length in preview row.
Indentation
Specifies the space width between edge to previewrow's text. Default is 18px.
LoadOnDemand
Specifies whether the preview row should be loaded on demand.

Loading PreviewRow on Demand

By default, WebGrid will render all preview row data at once on first load. This could cause several performance issues due to large output size, in the meantime user might not need to see all preview row's data at once.
In WebGrid.NET v5.0, you can configure WebGrid to skip row rendering in first load to reduce initial page output size. In this scenario, the preview row Expanded state is automatically set to false (Collapse). The preview row data will be retrieved through AJAX callback when you clicked on the expand icon. For more information, you can read Walkthrough: Configure WebGrid to load PreviewRow on demand.
