following is the code which is showing the data on the page now it is working on field change where i need to click the label field ….

static LabelField[] CrDrLabels;

    public LowerCreditors() throws Exception {

        super(VerticalFieldManager.VERTICAL_SCROLL);

        CrDrLabels = new LabelField[CrDrList.VendorNameArr.length];

        for (int i = 0; i < CrDrLabels.length; i++) {
            final int t = i;

            VerticalFieldManager hfm = new VerticalFieldManager(USE_ALL_WIDTH) {

                protected void sublayout(int Width, int Height) {

                    // TODO Auto-generated method stub

                    super.sublayout(Width, Height);

                    setPositionChild(getField(0), 15, 0);

                    setPositionChild(getField(1), Display.getWidth()
                            - getFont().getAdvance(CrDrList.VendorValArr[t])
                            - 10, 0);
                }
            };

            CrDrLabels[i] = new LabelField(CrDrList.VendorNameArr[i],
                    LabelField.FOCUSABLE | Field.USE_ALL_WIDTH) {
                protected boolean navigationClick(int status, int time) {
                    fieldChanged(this, 0);
                    return true;
                };
            };

            LabelField Value = new LabelField(CrDrList.VendorValArr[i]);
            CrDrLabels[i].setPadding(0, 170, 0, 0);

            hfm.add(CrDrLabels[i]);
            hfm.add(Value);

            add(hfm);


        }
    }

    public void fieldChanged(Field field, int context) {

        // TODO Auto-generated method stub
        for (int i = 0; i < CrDrList.VendorNameArr.length; i++) {
        getFieldWithFocus();
            if (field == CrDrLabels[i]) {

                String LN = CrDrLabels[i].getText();
                CrDrList.cname1 = LN;

                LabelField cname1 = CrDrLabels[i];
                CrDrList.selLad = CrDrLabels[i];

            }

        }
    }

and the the other code is

menu.add(new MenuItem("View last 5 days transaction", 20, 10) {
            public void run() {
                if(property.Status.equals("online"))
                {
                Viewlast5daystransaction();
                }

                else
                {
                    Dialog.alert("Please login Online to access the data..");
                }
            }

            String LedgerName = CrDrList.cname1;

            private void Viewlast5daystransaction() {
                //Dialog.alert("Last 5 Days Transaction");

                int resCode = 0;

                HttpConnection connection = null;
                try {
                    connection = getConn(property.LedgerDetailsURL);
                } catch (Exception e1) {
                    // TODO Auto-generated catch block
                    System.out.println(e1.getMessage());
                    e1.printStackTrace();
                }

                try {
                    resCode = connection.getResponseCode();
                } catch (Exception e1) {
                    // TODO Auto-generated catch block
                    e1.printStackTrace();
                }

                if(resCode==0)
                {
                    Dialog.alert("Internet Connectivity not available.. Please try again later..");

                    TallyA TA;

                    try {
                        TA = new TallyA();

                        UiApplication.getUiApplication().popScreen();
                        UiApplication.getUiApplication().pushScreen(TA);
                    } catch (Exception e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    }

                }

                sPostdata = "{\"tok\":\""
                        + CompanyList.tok;

                System.out.println("Postedddddd Dataaaaaaaaa" + sPostdata);
                try {
                    String response = LedgerSearchReport();

                    System.out.println("response" + response);

                    ParseBankdetails.parsebankdetails(response);

                    System.out.println("response : " + response);

                    if(response != null)
                    {
                    LastFiveDaysCr LF;
                    try {
                        LF = new LastFiveDaysCr();

                        UiApplication.getUiApplication().pushScreen(LF);
                    } catch (Exception e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    }
                    }

                    else
                    {
                        Dialog.alert("No Data..");
                        Creditiors LF;
                        try {
                            LF = new Creditiors();

                            UiApplication.getUiApplication().pushScreen(LF);
                        } catch (Exception e) {
                            // TODO Auto-generated catch block
                            e.printStackTrace();
                        }
                    }

                }
                catch (Exception e) {

                    e.printStackTrace();
                }

            }
        });

in this field only i want that instead of field change there should be focus change …
please help me on that …

I think you should implement the logic in “onFoucus()” method ,instead of using “onfieldChanged()” for CrDrLabels[i];
