Programmatically Select all values in ADF BC based selectMany (af:selectManyCheckbox, af:selectManyChoice, af:selectManyListbox, af:selectManyShuttle) component


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
check it - Set values in af:selectManyChoice programmatically - Oracle ADF

Create and set clientAttribute to ADF Faces component programmatically to pass value on client side JavaScript


This post is next in series of "Working with ADF Faces Components programmatically"

So this post is about creating client Attribute, applying it to component and setting it's value programmatically
this requirement comes in picture when user is dealing with dynamic layout means components are created programmatically at run time and it is not possible to apply clientAttribute and other properties declarative

In this i am extending my previous post -
Apply Client/Server listener to programmatically created components, apply JavaScript to ADF Faces components at run time

In previous post i have described about applying client listener and server listener programmatically
here we will see how to pass a variable value to java script function using client attribute
You can read more about af:clientAttribute here

From oracle docs-
The clientAttribute tag specifies the name/value for an attribute which will both be made available both on the server-side (Faces) component as well on on the client-side equivalent. This tag will be ignored for any server-rendered components, as it is only supported for the rich client. ClientAttributes are not synchronized to the server since unknown attributes from the client are not synchronized to the server.



Lets' see how we can do this ,It's simple just check this code -

//Code from previous post to create inputText programmatically 
//http://www.awasthiashish.com/2015/05/apply-clientserver-listener-to.html
        RichInputText ui = new RichInputText();
        ui.setValue("Programmatically Created Input Text");
        ui.setId("pit1");
        ui.setContentStyle("width:200px;color:navy");

Here i am not writing code to apply client/server listener again , refer previous post for that
See the code to add client attributes to component (inputText)

        // A Set that contains all clientAttributes
        java.util.Set<String> clientAttributes = new HashSet<String>();

        // Add client attribute's name
        clientAttributes.add("clientAttribute1");
        clientAttributes.add("clientAttribute2");
        clientAttributes.add("clientAttribute3");

        //Add these attributes to a UI Compoenent
        ui.setClientAttributes(clientAttributes);

        //here assign values to client attributes
        ui.getAttributes().put("clientAttribute1", "Oracle ADF");
        ui.getAttributes().put("clientAttribute2", 9999);
        ui.getAttributes().put("clientAttribute3", "Ashish Awasthi");

So all done , now check it
For that i have used this javascript method

function demoJsFunction(evt) {
                  var comp = evt.getSource();
                  alert(comp.getProperty('clientAttribute1'));
                  alert(comp.getProperty('clientAttribute2'));
                  alert(comp.getProperty('clientAttribute3'));
               
                  evt.cancel();
              }
 

this method is called using client listener on input text and see the alert messages
First client attribute value-

Second client attribute value-

Third client attribute value-

So this is working :)
