Creating Bindings

The OData V4 model offers the factory methods bindList, bindContext and bindProperty for creating bindings. Typically, these methods are not called directly in applications, but indirectly by the following:

• Binding an OpenUI5 control through an API such as oForm.bindElement("{/SalesOrderList('0500000000')}");

  This sample binds a form to a certain sales order so that form elements can be bound to display or change single properties of the sales order.

  Note:

  Note that binding expressions can be complex so that they can take additional properties to specify the binding further in addition to the path:

  
  oForm.bindElement({path : "/SalesOrderList('0500000000')", parameters : {$expand : "SO_2_SOITEM", ...}, events : {dataReceived : '.onDataEvents', ...}});
  

  This allows you, for instance, to specify OData V4 binding parameters such as $expand or attach to OData V4 Binding Events such as dataReceived.

  For a complete example, see the onSalesOrderSelect method (file: Main.controller.js) in the SalesOrders sample in the Demo Kit.

• Declaring a binding for a control property in an XML view such as the following:

      
  <Table items="{path : '/SalesOrderList', parameters : { $expand : 'SO_2_BP', $filter : 'BuyerName ge \'M\'', ...}, events : {dataReceived : '.onDataEvents', ... } }">
  

  For a complete example, see the Main.view.xml file in the SalesOrders sample in the Demo Kit.
