Time for action – using DataTable with multiple row selection support

In this section we will demonstrate how to select multiple user rows and disable the selected users.

Create a DataTable component with the multiple row selection mode enabled, using the following code:

<p:dataTable var="user" value="#{adminController.users}"  
    selection="#{adminController.selectedUsers}" rowKey="#{user.id}">

  <p:column selectionMode="multiple"/>

  <p:column headerText="Id" width="20px;">  
    <h:outputText value="#{user.id}" />
  </p:column>  

  <p:column headerText="Email" >
    <h:outputText value="#{user.emailId}" />
  </p:column>  
  <f:facet name="footer">
    <p:commandButton value="Disable" actionListener="#{adminController.disableSelectedUsers}"/>
  </f:facet>
</p:dataTable>
