Now let us create updateEmpRecords.jspx page in viewController project & Drop empFindAll object as ADF Table
 
Define custom SelectionListener method for the table :
   public void selectionListener(SelectionEvent selectionEvent) 
    { 
    // This method gets the Empno of the selected record & stores in the list object 
     UIXTable table = (UIXTable)selectionEvent.getComponent(); 
     FacesCtrlHierNodeBinding fcr 
     =(FacesCtrlHierNodeBinding)table.getSelectedRowData(); 
     Number empNo = (Number)fcr.getAttribute("empno") ;
      this.getSelectedRowsList().add(empNo); 
    }
Set table's selectedRowKeys to #{bindings.empFindAll.collectionModel.selectedRow}"
Drop inputText on the same jspx page that accepts Salary .Now we would like to drag records from the above table
 & drop that on the inputtext field.This feature can be achieved by inserting dragSource operation inside the table & 
dropTraget operation inside the inputText:
<af:dragSource discriminant="tab"/> //Insert this inside the table
<af:inputText label="Enter Salary" id="it13" autoSubmit="true" 
      binding="# {test.deptValue}"> 
      <af:dropTarget dropListener="#{test.handleTableDrop}"> 
      <af:dataFlavor 
       flavorClass="org.apache.myfaces.trinidad.model.RowKeySet"    discriminant="tab"/> 
      </af:dropTarget> 
      <af:convertNumber/> 
</af:inputText> 
In the above code when the user drags & drops multiple records on inputText,the dropListener method gets called.
Goto the respective page definition file & create updateEmprecords method action& execute action


dropListener method code: 
       public DnDAction handleTableDrop(DropEvent dropEvent) 
       { 
         //Below code gets the updateEmprecords method,passes parameters & executes method 
           DataFlavor<RowKeySet> df = DataFlavor.getDataFlavor(RowKeySet.class); 
           RowKeySet droppedKeySet = dropEvent.getTransferable().getData(df); 
           if (droppedKeySet != null && droppedKeySet.size() > 0) 
          { 
                 DCBindingContainer bindings =

                 (DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry(); 
                 OperationBinding updateEmp; 
                 updateEmp= bindings.getOperationBinding("updateEmprecords"); 
                 updateEmp.getParamsMap().put("sal", 
                 this.getDeptValue().getAttributes().get("value"));           
                 updateEmp.getParamsMap().put("empList", this.getSelectedRowsList()); 
                 updateEmp.execute();
                //Below code performs execute operation to refresh the updated records 
                OperationBinding executeBinding; 
                executeBinding= bindings.getOperationBinding("Execute"); 
                executeBinding.execute(); 
                AdfFacesContext.getCurrentInstance().addPartialTarget(dropEvent.getDragComponent());
                this.getSelectedRowsList().clear(); 
         } 
                return DnDAction.NONE; 
       }
Run updateEmpRecords.jspx page & enter any Salary say '5000'.
Select multiple records in table & drop these selected records on the inputText Salary.
Note that all the selected records salary value gets updated to 5000.
