在下面的示例中,我们正在实现< rich:dataGrid >组件。本示例包含以下文件。
// data-grid.xhtml
Data Grid
// StudentRecord.java
import java.util.ArrayList;
import java.util.List;
import javax.faces.bean.ManagedBean;
import javax.faces.bean.RequestScoped;
@ManagedBean
@RequestScoped
public class StudentRecord {
String id;
String name;
String email;
String contactNumber;
List records;
public StudentRecord(){}
public StudentRecord(String id, String name, String email, String contactNumber) {
this.id = id;
this.name = name;
this.email = email;
this.contactNumber = contactNumber;
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getEmail() {
return email;
}
public void setEmail(String email) {
this.email = email;
}
public String getContactNumber() {
return contactNumber;
}
public void setContactNumber(String contactNumber) {
this.contactNumber = contactNumber;
}
public List getRecords() {
records = new ArrayList<>();
records.add(new StudentRecord("101", "Raju", "raju@abc.com", "52534252"));
records.add(new StudentRecord("102", "Rama", "rama@abc.com", "52235252"));
records.add(new StudentRecord("103", "John", "john@abc.com", "52456252"));
records.add(new StudentRecord("104", "Peter", "peter@abc.com", "55625252"));
return records;
}
public void setRecords(List records) {
this.records = records;
}
public int getNumberOfRecords(){
return this.records.size();
}
}
输出:
