ADF 11G : How to Add a Row at the different place of the ADF Table?

ADF 11G : How to Add a Row at the different place of the ADF Table?

Approach:1- Override the insertRow(row) method :

public class EmployeesViewImpl extends ViewObjectImpl {
    /**
     * This is the default constructor (do not remove).
     */
    public EmployeesViewImpl() {
    }

    @Override
    public void insertRow(Row row) {
        super.insertRow(row);
        row.removeAndRetain();
         last();
         next();
         getDefaultRowSet().insertRow(row);
    }
}



Approach:2- Calling the action:


public String insertRowAtFirstOfTable{
CollectionModel tableModel = (CollectionModel)getEmpTable().getValue();
JUCtrlHierBinding adfModel = (JUCtrlHierBinding)tableModel.getWrappedData();
DCIteratorBinding dciter = adfModel.getDCIteratorBinding();
NavigatableRowIterator nav=dciter.getNavigatableRowIterator();
Row newRow = nav.createRow();
newRow.setNewRowState(Row.STATUS_INITIALIZED);
nav.insertRowAtRangeIndex(0, newRow);        dciter.setCurrentRowWithKey(newRow.getKey().toStringFormat(true));
return null;
}



public String insertRowAtLastOfTable() {
// Add event code here…
CollectionModel tableModel = (CollectionModel)getEmpTable().getValue();
JUCtrlHierBinding adfModel = (JUCtrlHierBinding)tableModel.getWrappedData();
DCIteratorBinding dciter = adfModel.getDCIteratorBinding();
NavigatableRowIterator nav=dciter.getNavigatableRowIterator();
Row newRow = nav.createRow();
newRow.setNewRowState(Row.STATUS_INITIALIZED);
Row lastRow = nav.last();
int lastRowIndex = nav.getRangeIndexOf(lastRow);
nav.insertRowAtRangeIndex(lastRowIndex+1, newRow);
dciter.setCurrentRowWithKey(newRow.getKey().toStringFormat(true));
return null;
}


public String addRowBeforeCurrentSelectedRow() {
// Add event code here…
CollectionModel tableModel = (CollectionModel)getEmpTable().getValue();
JUCtrlHierBinding adfModel = (JUCtrlHierBinding)tableModel.getWrappedData();
DCIteratorBinding dciter = adfModel.getDCIteratorBinding();
NavigatableRowIterator nav=dciter.getNavigatableRowIterator();
Row newRow = nav.createRow();
newRow.setNewRowState(Row.STATUS_INITIALIZED);
nav.insertRow(newRow);        dciter.setCurrentRowWithKey(newRow.getKey().toStringFormat(true));
return null;
}

public String addRowAfterCurrentSelectedRow() {
// Add event code here…
CollectionModel tableModel = (CollectionModel)getEmpTable().getValue();
JUCtrlHierBinding adfModel = (JUCtrlHierBinding)tableModel.getWrappedData();
DCIteratorBinding dciter = adfModel.getDCIteratorBinding();
NavigatableRowIterator nav=dciter.getNavigatableRowIterator();
Row newRow = nav.createRow();
newRow.setNewRowState(Row.STATUS_INITIALIZED);
Row currentRow = nav.getCurrentRow();
int currentRowIndex = nav.getRangeIndexOf(currentRow);
nav.insertRowAtRangeIndex(currentRowIndex+1, newRow);
dciter.setCurrentRowWithKey(newRow.getKey().toStringFormat(true));
return null;
}

Approach 3

    public String save() {
        String amDef = "model.AppModule";
        String config = "AppModuleLocal";
        ApplicationModule am = Configuration.createRootApplicationModule(amDef, config);
        ViewObject vO=am.findViewObject("StudentVO1");

        StudentVORowImpl studentRow=(StudentVORowImpl)vO.createRow();


     
        studentRow.setRoll("0001");
        studentRow.setName("Success");
        vO.insertRowAtRangeIndex(1, studentRow);

        am.getTransaction().commit();
     
        return "back";
    }
