Data binding

ListView provides the option to load the data either from local data sources or remote data services. This can be done through dataSource property which supports the data type of array or through DataManager.

ListView supports different kind of data services such as OData, OData V4, Web API and data formats like XML, JSON, JSONP with the help of DataManager Adaptors.

Fields	Type	Description
id	string	Specifies ID attribute of list item, mapped in dataSource.
text	string	Specifies list item display text field.
isChecked	string	Specifies checked status of list item.
isVisible	string	Specifies visibility state of list item.
enabled	string	Specifies enabled state of list item.
iconCss	string	Specifies the icon class of each list item which will be add before to inner text.
child	string	Specifies child dataSource fields.
tooltip	string	Specifies tooltip title text field.
groupBy	string	Specifies category of each list item.
sortBy	string	Specifies sorting field, which is used to sort the listview data.
htmlAttributes	string	Specifies list item html attributes field.

When complex data bind to ListView, you should map the fields properly. Otherwise, the ListView properties remain as undefined or null.

Bind to local data

Local data represents in two ways, which are described below.

Array of simple data
Array of JSON data.

Array of simple data

ListView supports to load the array of primitive data like string and numbers. Here, both value and text field act as same.

}

Array of JSON data

ListView can generate its list items through an array of complex data. To get it work properly, you should map the appropriate columns to field property.

The below example illustrates the concept of binding Array of JSON data.

Bind to remote data

ListView supports to retrieve the data from remote data services with the help of DataManager component and Query property allows to fetch data and return it to ListView from the database.

In the below sample, displayed first 6 Products from Product table of NorthWind data service.
