How to get all the selected rows from a table in ADF.

How get all the selected rows from the UI ADF table.

For example you want to print all the departments which you have selected in the UI..
 
1. In the Table property inspector make rowSelection="multiple". And
Go to the Binding in Advanced option. Select the managed bean (or create new managed Bean) where you want to access this this Table. And create new property. (just give one new name)



Like below it will generate the code in the managed bean for the RichTable.

   private RichTable departmentTable;

   public void setDepartmentTable(RichTable departmentTable) {
        this.departmentTable = departmentTable;
    }
    public RichTable getDepartmentTable() {
        return departmentTable;
    }

2. Now you can access the selected rows from the table using below code.

RowKeySet selectedRowKeySet = this.getDepartmentTable().getSelectedRowKeys();
System.out.println("Number of rows:"+ selectedRowKeySet.size());

Using "selectedRowKeySet" you can iterate and get all the department data by rowwise

You can write this code in the SelctionListner of the Table itself so that if you want to perform any operations on selction of rows. as shown below.

FacesContext fc =FacesContext.getCurrentInstance();
RowKeySet selectedRowKeySet = this.getDepartmentTable().getSelectedRowKeys();
       
ExpressionFactory ef = fc.getApplication().getExpressionFactory();
 MethodExpression me = ef.createMethodExpression(fc.getELContext(),       "#{bindings.DepartmentVO1.collectionModel.makeCurrent}", null,
                                                     new Class[] { SelectionEvent.class });
        me.invoke(fc.getELContext(), new Object[] { selectionEvent });
        System.out.println("Number of rows:"+ selectedRowKeySet.size());

This works properly even if you have the dependent fragments. Like if you have Employee fragment depend on Departments selection.


The image is shown below where you have selected multiple rows.

How to show the pop-up by programmatically

Recently i was working one feature in ADF, where i wanted to show the pop-up programmatically.  I searched in the net but could'nt find the proper solution. So thought of posting this solution.


You can display the pop-up easily using <af:showPopupBehavior triggerType="action" popupId=":::p2"/>.
But in some situation if you want to do through Managed bean, follow the below procedure.

1. Add the popup component to your jsff (fragment page) with the dialog box in it, with the whatever message you want.


2. In the managed bean instantiate an Object of RichPopup with the setters and getters method, Below is the Managed bean code fragment for showing the Popup.

 public class ShowPopUp{
    private RichPopup richpopupId;
   
    public void setRichpopupId(RichPopup richpopupId) {
        this.richpopupId = richpopupId;
    }

    public RichPopup getRichpopupId() {
        return richpopupId;

  public void showPopup(){

  String popupId="p1";
  FacesContext context = FacesContext.getCurrentInstance();
  StringBuilder script = new StringBuilder();
  ExtendedRenderKitService extRenderKitSrvc = Service.getRenderKitService(context,            ExtendedRenderKitService.class);
  script.append("var popup = AdfPage.PAGE.findComponent('"+popupId+ "'); ").append("popup.show();");
  extRenderKitSrvc.addScript(context, script.toString());

}
}
 
In the above code String popupId="p1"; , p1 is the Id of the popup which you have added in 1st step.

3. Now go to the popup in the structure window of the jsff page, then go to the Advanced option in the Property inspector. In the Binding bind it to the "richpopupId" of the managed bean.
