The Angular Tree Grid/Tree table is a feature-rich control used to visualize self-referential hierarchical (tree-like structure) data effectively in a tabular format. Its rich feature set includes many functionalities like data binding, editing, sorting, filtering, paging, aggregating rows, and exporting to Excel, CSV, and PDF formats.
Bind data seamlessly with various local and remote data sources such as JSON, RESTful services, OData services, and WCF services. It uses the data manager to handle data and supports customizing data requests and processing.
All Tree Grid features work on touch devices with zero configuration. Without customization, the Tree Grid control allows enabling features such as sorting, paging, and selection.
Responsive feature allows the Tree Grid layout to be viewed on various devices. It is also possible to hide specific columns for particular screen sizes using column-based media query support.
The pager UI is adaptable in mobile views. When a Tree Grid is rendered in a smaller screen, the pager UI will be rendered without a page number list making it suitable for smaller devices.
The Tree Grid works well with all modern web browsers such as Chrome, Firefox, Edge, Safari, and IE11. It supports IE11 with the help of poly fills.
The Angular Tree Grid provides full support to create, read, update, and delete operations (CRUD). It performs editing operations with JSON collection or remote data service with the help of data manager.
Easily visualize the aggregates of the Tree Grid column values using the summary option. Aggregates can be customized to show their value in every hierarchy with a set of predefined summary types.
Through paging, a segment of data can be viewed from the assigned data source. The Angular Tree Grid offers built-in pager UI with options to customize its entire UI. It also has an on-demand paging mode for effective data retrieval from remote web services.
Filtering allows users to view the required data in the Tree Grid. The TreeGrid supports various filter types such as filter bar and menu. The appropriate filter type can be chosen based on the application. These filter types support number, string, date, and Boolean. Options to customize filter operators, case sensitivity, and diacritics are also available.
The Tree Grid allows users to sort a column by simply clicking on the header. A Ctrl + header click performs multi-sorting. Allows sorting data either in the ascending or descending order.
Tree Grid allows selecting rows or cells. One or more rows or cells can also be selected by holding Ctrl or Command, or programmatically.
Allows changing the Tree Grid size by setting the width and height properties. Horizontal and vertical scrollbars will appear when the content overflows the Tree Grid element. For the Tree Grid to fill its parent container, the user has to simply set the height and width to 100%.
Using templates, users can create custom user experiences in the Tree Grid It provides various template options to create custom headers, custom cell contents, and toolbars.
Columns define the schema of a data source in Tree Grid. It supports formatting, column definitions, text wrapping, column chooser, column menu, column reorder, and other important features.
The Angular Tree Grid Context Menu provides a list of actions to be performed. It appears when a cell, header, or pager is right-clicked. The context menu items can be customized according to user preference.
Stacked headers allow grouping and visualizing column headers in a stacked manner. There is no limit to the number of columns that can be stacked. The data columns can still be sorted and filtered.
Row heights can be adjusted to display more rows in a view port. It is also possible to set row height conditionally.
With continuous improvement in Angular versions, the Angular Tree Grid is kept up to date to make it compatible with versions starting from 4 to the latest version.
Easily export the Tree Grid control in various file formats such as Excel, PDF, or CSV. Users can also programmatically customize the exported document.
Allows users to print data either by using the print option from the toolbar or programmatically. Print all the rows of a Tree Grid regardless of the number of pages it has. It also has an option to print the currently viewed page alone.
Four built-in SASS-based themes are available such as: Material, Bootstrap, Fabric, and High Contrast. Simplify theme customization either by overriding the existing SASS styling or creating custom themes by using the Theme Studio application.
The Angular Tree Grid ensures that every cell is accessible using the keyboard. Major features like sorting, selection, and editing can be performed using keyboard commands alone; no mouse interaction required. This helps in creating highly accessible applications using this component.
The Angular Tree Grid has complete WAI-ARIA accessibility support. The Tree Grid UI includes high-contrast visual elements, helping visually impaired people to have the best viewing experience. Also, the valid UI descriptions are easily accessible through assistive technologies such as screen readers.
Tree Grid enables users from different locales to use it by formatting the date, currency, and numbering to suit locale preferences. It uses the internalization (i18n) library to handle value formatting.
Right-to-left rendering allows displaying the text and layout of the Tree Grid from right to left. This improves the user experience and accessibility for RTL languages.
Based on their needs, users can allow localizing all the strings that are used in the user interface of Angular Tree Grid control. It uses the localization (l10n) library to localize UI strings.
