Reg Row Selection in a Table UI Element

Question

Hi All,
Can anyone help me in writing code to select a row from a table.
I need to read the data from a row selected in a table and print it in the next page of my application.
I request anyone to send me some coding line on how to select a row from a table and read data from it.
Regards,
Murthy.

Hi Narayana,
Follow the steps.
Step1: Create a WD Component.
Step2:  Under Component Controller create a
i)  2  Node “EmployeeInfo” and “EmployeeRecord”  with attribute “EmployeeName” and “Position”  of cardinality 0..n for both the node and a context attribute “WindowInstance” of type “com.sap.tc.webdynpro.services.session.api.IWDWindow”
Step3: Go to the Diagram View. Do the mapping between “EmployeeView” and “Component Controller” and between “DisplayView” and “Component Controller”
Step4: Design 2 Views layout
i>EmployeeView
Layout like
Employee Name |                                  Employee Position
EmployeeInfo.EmployeeName| EmployeeInfo.Position
EmployeeInfo.EmployeeName| EmployeeInfo.Position
DisplayResultButton
ii>DisplayView
Layout like
Employee Name   |                      Employee Position
EmployeeRecord.EmployeeName |    EmployeeRecord.Position
EmployeeRecord.EmployeeName |    EmployeeRecord.Position
CloseWindowButton
Step5: Create 2 Windows
1>EmployeeWindow
2>DisplayWindow.
Under “EmployeeWindow” add the “EmployeeView”
and “DisplayWindow” add the “DisplayView”
Step5: Associate action “DisplayResult” with the “DisplayResultButton” and use this code inside the Implementation of “EmployeeView”
public void wdDoInit()
    //@@begin wdDoInit()
//initialize nodes
wdContext.nodeEmployeeInfo().addElement(wdContext.createEmployeeInfoElement());
wdContext.nodeEmployeeRecord ().addElement(wdContext.createEmployeeRecordElement());
    //@@end
public void onActionDisplayResult(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
    //@@begin onActionDisplayResult(ServerEvent)
try
IPrivateDisplayView.IEmployeeRecordElement empRec =
wdContext.createEmployeeRecordElement();
int n = wdContext.nodeEmployeeInfo().size();
int leadSelected = wdContext.nodeEmployeeInfo().getLeadSelection();
// loop backwards to avoid index troubles     
for (int i = 0; i < n ; i++) {
if (wdContext.nodeEmployeeInfo().isMultiSelected(i) || leadSelected == i) {
empRec.setEmployeeName(wdContext.nodeEmployeeInfo().getElementAt(i).getAttributeValue("EmployeeName"));
empRec.setPosition(wdContext.nodeEmployeeInfo().getElementAt(i).getAttributeValue("Position"));
wdContext.nodeEmployeeRecord().addElement(empRec);
catch(Exception e)
e.printStackTrace();
IWDWindowInfo windowInfo =(IWDWindowInfo) wdComponentAPI.getComponentInfo().findInWindows(
     "DisplayWindow");
//        create the Window
     IWDWindow window = wdComponentAPI.getWindowManager().createWindow(windowInfo, true);
     window.setWindowPosition(WDWindowPos.CENTER);
     window.setTitle("WindowTitle");
     window.setWindowSize(200,200);
//        Save WindowInstance in Context
     wdContext.currentContextElement().setWindowInstance(window);
//        and show the window
     window.show();
     //wdThis.wdFirePlugInDisplay();
    //@@end
Step6: Associate action “CloseWindow” with the “CloseWindowButton
” and use this code inside implementation of  “DisplayView”
  public void onActionCloseWindow(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
    //@@begin onActionCloseWindow(ServerEvent)
   IWDWindow window = wdContext.currentContextElement().getWindowInstance();
   window.destroyInstance();
    //@@end
