Programmatically populate values in ADF Faces multiSelect component (af:selectManyCheckbox, af:selectManyChoice, af:selectManyListbox, af:selectManyShuttle)

Hello All,
Previously i have posted a lot about component that supports multiple selection in ADF Faces (af:selectManyCheckbox, af:selectManyChoice, af:selectManyListbox, af:selectManyShuttle)
- Multiple Selection in ADF Faces

This post is about selecting all values in a component programmatically on a event like button click, value change event etc.
Note that this post is designed for ADF BC (viewObject) based components , to set values in bean based component check this-
Programmatically populate values in ADF Faces multiSelect component (af:selectManyCheckbox, af:selectManyChoice, af:selectManyListbox, af:selectManyShuttle)

So for this i have just dropped Departments viewObject as multiSelect component on page
(af:selectManyCheckbox, af:selectManyChoice, af:selectManyListbox, af:selectManyShuttle)

 Page bindings section looks like this-

Now see code of Set all values as selected button-

    /**Method to get BindingContainer of current viewPort (page)
     * @return
     */
    public BindingContainer getBindings() {
        return BindingContext.getCurrent().getCurrentBindingsEntry();
    }

    /**Method to set all values as selected in SelectMany Components.
     * @param actionEvent
     */
    public void setAllValuesToSelected(ActionEvent actionEvent) {

        int arrIndex[];
        //Get the iterator binding of component
        DCIteratorBinding deptIter = (DCIteratorBinding) getBindings().get("DepartmentsView1Iterator");
        //Get viewObject from Iterator
        ViewObject deptVo = deptIter.getViewObject();
        //Get component list binding , component is directly based on this
        JUCtrlListBinding list = (JUCtrlListBinding) getBindings().get("DepartmentsView1");
        DCIteratorBinding iterList = list.getDCIteratorBinding();
        RowSetIterator rsi = deptVo.createRowSetIterator(null);
        int i = 0;
        int rowCount = (int) deptVo.getEstimatedRowCount();
        //Initialize array and set it's size (equal to number of rows in List)
        arrIndex = new int[rowCount];
        while (rsi.hasNext()) {
            //Get viewObject next row from RowSetIterator
            Row nextRow = rsi.next();
            //Set this row as page iterator's current row
            iterList.setCurrentRowWithKey(nextRow.getKey().toStringFormat(true));
            //Now get index of this row
            int indx = iterList.getCurrentRowIndexInRange();
            //Add it to array
            arrIndex[i] = indx;
            i++;
        }
        rsi.closeRowSetIterator();
        // Set as selected indices
        list.setSelectedIndices(arrIndex);
    }

All done, now run and check application , click on button and see what happens ?

Great, it's working :)
I have explained one more approach to set values in multi select component that makes use of component binding

 This post is about a very common question

How to set selected values in af:selectManyChoice component ?
Sometimes we need to set some values in selectManyChoice component on some action

In this post i am using Departments table of HR Schema to create selectManyChoice (Multiple Selection)
Just drag and drop Departments viewObject as ADF Select Many Choice
see- Using Multiple Selection (selectManyListbox & selectManyCheckbox component) in ADF

(Jdev Version- 12.1.3)
dropped a button on page and on this button action ,  setting values in component
See this simple managed bean code -

import java.util.ArrayList;

import javax.faces.event.ActionEvent;

import oracle.adf.view.rich.component.rich.input.RichSelectManyChoice;
import oracle.adf.view.rich.context.AdfFacesContext;

public class SetValueSmcBean {
    private RichSelectManyChoice selectMcBind;

    public SetValueSmcBean() {
    }

    /**Methos to set selected values in SelectManyChoice
     * @param actionEvent
     */
    public void setSelectedValuesAction(ActionEvent actionEvent) {
        ArrayList listVal = new ArrayList(20);
        //Add DepartmentId to list that you want to set as selected
        listVal.add(101);
        listVal.add(102);
        // Set this List as value using component binding
        selectMcBind.setValue(listVal.toArray());
        //Refresh Component on page (partial target)
        AdfFacesContext.getCurrentInstance().addPartialTarget(selectMcBind);
    }

    public void setSelectMcBind(RichSelectManyChoice selectMcBind) {
        this.selectMcBind = selectMcBind;
    }

    public RichSelectManyChoice getSelectMcBind() {
        return selectMcBind;
    }
}

run application and check-
