The TreeGrid uses DataManager
, which supports both RESTful JSON data services binding and local JavaScript object array binding. The dataSource
property can be assigned either with the instance of DataManager
or JavaScript object array collection.
It supports two kinds of data binding method:
In Local Data binding, data source for rendering the TreeGrid control is retrieved from the same application locally.
Two types of Data binding are possible with the TreeGrid control.
To bind local data to the treegrid, you can assign a JavaScript object array to the dataSource
property. The local data source can also be provided as an instance of the DataManager
.
By default,
DataManager
usesJsonAdaptor
for local data-binding.
The childMapping
property is used to map the child records in hierarchy data source.
The following code example shows you how to bind the hierarchical local data into the TreeGrid control.

To bind remote data to TreeGrid component, assign service data as an instance of DataManager
to the dataSource
property. To interact with remote data source, provide the endpoint url
and define the hasChildMapping
property of treegrid.
The hasChildMapping
property maps the field name in data source, that denotes whether current record holds any child records. This is useful internally to show expand icon while binding child data on demand.
The TreeGrid provides Load on Demand
support for rendering remote data. The Load on demand is considered in TreeGrid for the following actions.
When load on demand is enabled, all the root nodes are rendered in collapsed state at initial load.
When load on demand support is enabled in TreeGrid with paging, the current or active page’s root node alone will be rendered in collapsed state. On expanding the root node, the child nodes will be loaded from the remote server.
When a root node is expanded, its child nodes are rendered and are cached locally, such that on consecutive expand/collapse actions on root node, the child nodes are loaded from the cache instead from the remote server.
Similarly, if the user navigates to a new page, the root nodes of that specific page, will be rendered with request to the remote server.

By default,
DataManager
usesODataAdaptor
for remote data-binding. Based on the RESTful web services, set the corresponding adaptor to DataManager. Referhere
for more details. Filtering and searching server-side data operations are not supported in load on demand
On remote data binding, all treegrid actions such as paging, loading child on-demand, will be processed on server-side. To avoid postback, set the treegrid to load all data on initialization and make the actions process in client-side. To enable this behavior, use the offline
property of DataManager
.

You can create your own adaptor by extending the built-in adaptors. The following demonstrates custom adaptor approach and how to add a serial number for the records by overriding the built-in response processing using the processResponse
method of the WebApiAdaptor
.

During server interaction from the treegrid, some server-side exceptions may occur, and you can acquire those error messages or exception details
in client-side using the actionFailure
event.
The argument passed to the actionFailure
event contains the error details returned from the server.

The
actionFailure
event will be triggered not only for the server errors, but also when there is an exception while processing the treegrid actions.
You can use TreeGrid dataSource
property to bind the data source to TreeGrid from external Ajax request. In the below code we have fetched the data source from the server with the help of Ajax request and provided that to dataSource
property by using onSuccess
event of the Ajax.
