In this post, We’ll see how to select all values in a component programmatically on an event like button click, value change event etc.
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
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

Cheers 🙂 Happy Learning
