Grid Widget
Use the Grid widget to inspect, view, and analyze data from an infotable source. Each infotable column in the data source is displayed as a column on the Grid.
The following configurations are available in ThingWorx 9.4.2 or later:
• Trigger a ServiceInvokeCompleted event on the data service when expanding nodes in a tree grid.
The following configurations are available in ThingWorx 9.4 or later:
• Display custom actions on the grid toolbar.
• Highlight new rows that are added to the grid.
• Configure the ShowRowNumbers property dynamically.
The following configurations are available in ThingWorx 9.3.7 or later:
• Keep the selected row IDs when the grid is paginated and the page is changed.
The following configurations are available in ThingWorx 9.3.6 or later:
• Trigger an event instead of opening a URL when a hyperlink is clicked. For example, you can pass link data and navigate to a mashup.
The following configurations are available in ThingWorx 9.3.4 or later:
• Bind child data to create a hierarchal tree grid with multiple levels of parent and child data.
• Set the maximum number of rows that users can expand at run time.
• Migrate legacy dynamic configurations from advanced grids.
• Expand rows automatically by specifying the ID of a row in a service.
• Disable parent rows and their children.
• Configure the selection behavior of the focus box when using keyboard navigation.
• Configure the visibility and icons of validation messages on the Validation panel.
The following configurations are available in ThingWorx 9.3 or later:
• Enable editing on a grid, row, or cell level.
• Resize and reorder columns at run time.
• Display a run-time menu that enables users to show, hide, and reorder columns on the grid.
• Define validation rules and messages to validate input when editing is enabled.
• Display row number in a separate column.
• Set a minimum and a maximum width for the grid columns.
• Configure the widget dynamically using JSON configuration data.
 |
You must update the output of existing data services for the Grid (Advanced) widget to JSON.
|
• Add a footer section.
• Display a confirmation message when deleting rows. This configuration is available in ThingWorx 9.3.1 or later.
The following is a list of available configurations in ThingWorx 9.2:
• Format data columns using renderers and apply state formatting.
• Sort column data in a descending or an ascending order.
• Filter data using a filter box.
• Align content within the header and body cells.
• Display a check box for row selection.
• Set the column width automatically or manually using pixel, percentage, or fraction values.
• Display the header and body rows as a single line and prevent text wrapping.
• Set the minimum and maximum height of the grid rows.
• Select single or multiple rows on the grid.
In addition, you can combine the Grid with other widgets such as the Pagination, Chip Based Data Filter, and the Toolbar to create unique and interactive data views within a mashup.

The Grid widget is also available as a web component in the ThingWorx Web Component SDK.

Performance Considerations
The Grid widget supports large data sets that contain millions of rows. However, displaying millions of rows impacts load time performance, and makes it difficult to find and analyze information. Following are best practices for the Grid widget:
• Avoid creating data tables with millions of rows.
• Set appropriate minimum and maximum row height to display data rows in an accessible way.
• Use pagination to break large sets into multiple pages and allow users to control how many rows to display on each page.
