Search Container in Liferay 7

Here we will learn how to display all records of Product table created in my previous post which include three cloumns.

1. productId
2. productName
3. productPrice

Step1 Open view.jsp page.Goto Windows→Show View→Snippets as shown here

Now navigate to Liferay UI Search Container → Model Search Container→Browse

From here select Product Entity as shown below.

This will insert liferay-ui:search-container code in your view.jsp as shown below.

<liferay-ui:search-container delta="5" deltaConfigurable="true" emptyResultsMessage="no-products">

<liferay-ui:search-container-results results="<%= ProductLocalServiceUtil.getProducts(searchContainer.getStart(), searchContainer.getEnd()) %>" />

<liferay-ui:search-container-row

className="com.liferay.product.service.model.Product"

modelVar="aProduct">

<liferay-ui:search-container-column-text property="productId"/>

<liferay-ui:search-container-column-text property="productName"/>

<liferay-ui:search-container-column-text property="productPrice"/>

  </liferay-ui:search-container-ow>

<liferay-ui:search-iterator />

</liferay-ui:search-container>

Here we use various tags which are explained as follow.

1. <liferay-ui:search-container delta="" deltaConfigurable="" emptyResultsMessage=""/>
