A SAP UI5 application using Element binding in Web-IDE

Data Binding is used to maintain a data sink between two systems.

We have different data binding techniques when we come to SAP UI5.

The different data binding techniques are:

One-way binding: The data flows from model to the controller.

Two-way binding: In two way binding the data flows from model to controller and vice-versa.

Aggregation binding: In which we create a local JSON file within the model, which is light weight to store data and directly we can access in the application.

Expression binding: In expression binding we can perform certain simple calculations and format the view.

OData binding : To access the data in the real server.


Now coming to our application.
Step 1: Go to Web IDE click on file -> New -> Project from template.

Step 2: As we gonna create a SAPUI5 application, select SAPUI5 Application and click on Next.

Step 3: Provide project name and descriptor namespace which is our manifest.json file. We create a descriptor to configure our app. Click on Next.

Step 4: Provide the view name and click on Next.

Step 5: click on Finish.

Step 6: Create a JSON file with in main folder and write the code as follows.

“Name”: “Divya B”,
“Street”: “Vinayaka Nagar”,
“HouseNumber”: “16”,
“ZIPCode”: “5330003”,
“City”: “Visakhapatnam”,
“Country”: “India”,
“Url”: “”,
“Twitter”: “@div”,
“Tel” : “+91 9898989898”,
“Email” : “”

Step 7: (opensap/nav/view/App)

Bind the each input field using element binding as below.

<Input value=”{address>/Name}”/>

<f:SimpleForm id="simpleFormChange" title="Address" editable="true" class="editableForm">
<Label text="{i18n>layoutFormName}"/>
<Input value="{address>/Name}"/>
<Label text="{i18n>layoutFormStreet}"/>
<Input value="{address>/Street}"/>
<Label text="{i18n>layoutFormHouseNumber}"/>
<Input value="{address>/HouseNumber}"/>
<Label text="{i18n>layoutFormZIPCode}"/>
<Input value="{address>/ZIPCode}"/>
<Label text="{i18n>layoutFormCity}"/>
<Input value="{address>/City}"/>
<Label text="{i18n>layoutFormGender}"/>
<core:Item text="{i18n>layoutGenderMale}"/>
<core:Item text="{i18n>layoutGenderFemale}"/>


Step 8: ( opensap/nav/Controller/App ) Write the code as follows in the controller. Here we are trying to access i18n properties.

	function(Controller) {
		"use strict";
	return	Controller.extend("opensap.nav.Controller.App",{
inIt: function() {
		// read msg from i18n model
			var oBundle = this.getView().getModel("i18n").getResourceBundle();

Step 9: ( opensap/nav/i18n/i18nproperties )

All the descriptions and labels are maintained here.


layoutDraftButton=Save Draft

# Layout Content
layoutFormHouseNumber=Door No.
layoutFormZIPCode=ZIP Code
layoutDraftButton=Save Draft

Step 10: Component.js

In order to configure you application and set the manifest & access our custom styles file, write the code as follows.

], function (UIComponent) {
	"use strict";

	return UIComponent.extend("opensap.nav.Component", {

		metadata : {
			manifest: "json",
			includes: ["css/style.css"]

		init : function () {
			// call the init function of the parent
			UIComponent.prototype.init.apply(this, arguments);


Step 11: Here we add properties of different components we used in the application like, style.css, Address.json etc. in the sap.ui5 part of manifest.json.

"sap.ui5": {
		"_version": "1.2.0",
		"rootView": {
			"viewName": "opensap.nav.view.App",
			"type": "XML",
			"id": "app"
		"autoPrefixId": true,
		"dependencies": {
			"minUI5Version": "1.34",
			"libs": {
				"sap.ui.core": {
					"minVersion": "1.34.0"
				"sap.m": {
					"minVersion": "1.34.0"
				"sap.ui.layout": {
					"minVersion": "1.34.0"
		"contentDensities": {
			"compact": true,
			"cozy": true

		"models": {
			"i18n": {
				"type": "sap.ui.model.resource.ResourceModel",
				"settings": {
					"bundleName": "opensap.nav.i18n.i18n"
		"Address": {
				"type": "sap.ui.model.json.JSONModel",
				"uri": "model/Address.json"

Step 12: The output is as follows.

Further I will explain Aggregation binding by adding some more functionality.

  • Hi,

    Input field doesn’t have aggregation binding, it only contains property binding. Aggregation binding implies that you have more than one value to bind for the UI control (eg: List box)

    I don’t see any new information in this blog…. 🙁

  • Change this line in Step 7:

    Aggregation binding can be assigned to our input values as follows:

    <Input value=”{tradescreen>/Company}” class=”Product sapMInputBaseInner”/>
