Data Binding in JavaScript QueryBuilder control

29 Sep 2022 / 9 minutes to read

The Query Builder uses DataManager to bind the datasource, 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 kind of databinding method:

  • Local data
  • Remote data

Local data

To bind local data to the query builder, you can assign the dataSource property with a JavaScript object array. The local data source can also be provided as an instance of the DataManager.

By default, DataManager uses JsonAdaptor for local data-binding.

Remote data

To bind remote data to the query builder, assign service data as an instance of DataManager to the dataSource property. To interact with remote data source, provide the endpoint url.

By default, DataManager uses ODataAdaptor for remote data-binding.

Binding with OData services

OData is a standardized protocol for creating and consuming data. You can retrieve data from OData service using the DataManager. Refer to the following code example for remote Data binding using OData service.

Binding with OData v4 services

The ODataV4 is an improved version of OData protocols, and the DataManager can also retrieve and consume OData v4 services. For more details on OData v4 services, refer to the odata documentation. To bind OData v4 service, use the ODataV4Adaptor.

Complex Data Binding allows you to create subfield for columns. To implement complex data binding, either bind the complex data in nested columns or specify complex data source and separator must be given in querybuilder.

In the following sample, complex data was bound in nested columns.
