Hi Padma
You might be filling values in Sports using Enumeration datatype or Value Set.
The Control CheckBoxGroup has an Event onToggle just create an action on that
event and add two parameters to that method in Action Tab of the View.
1. checked type boolean
2. index type integer
Also you need to map these parametrs
using the piece of code:
wdDoModifyView
if(firstTime){
IWDCheckBoxGroup chg = (IWDCheckBoxGroup)view.getElement("<UI element ID>");
IWDParameterMapping params = chg.mappingOfOnToggle();
params.addSourceMapping("checked","checked");
params.addSourceMapping("index","index");
}
now on each click of check box this method will get executed and you can directly
read the index of the check box and it is checked or unchecked ..
hope it is clear.
Regards
Abhimanyu L

The code which i used for creating sports checkbox group is .Here the prob is if i click on anyting it is not getting displayed..by default BaseBall is getting displayed that also one time only..if i go back to the view where this sports checkbox group is present BaseBall is not getting displayed and the previously selceted values are also not cleared
String sports[]=new String[]
{
"BaseBall",
"Cricket",
"Hockey",
"FootBall" ,
"Swimming",
"Running",
};
List SportsNodeEle=new ArrayList();
for(int i=0;i<sports.length ;i++)
{
IPrivateGeneralInfoView.IPersonalElement sportsVal=wdContext.createPersonalElement();
sportsVal.setSports(sports<i>);
SportsNodeEle.add(sportsVal);
}
wdContext.nodePersonal().bind(SportsNodeEle);
Hi Padma,
You have to use this code to put the valid values for sports in the sports attribute.
You can put this code in wdDoInit().
IModifiableSimpleValueSet valueSet = wdContext.nodePersonal().getNodeInfo().getAttribute(IPublicTestComp.IPersonalElement.SPORTS).getModifiableSimpleType().getSVServices().getModifiableSimpleValueSet();
valueSet.put("CRICKET", "Cricket");
valueSet.put("BASKET", "Basket Ball");
valueSet.put("TT","Table Tennis");
Also check my previous reply which is modified.

Hi by working in the way you suggested it is giving runtime error as given below...
I wrote the code in wdDoInit() method.
can u help me..its very urgent and one more thing..Instead of sports i took Months and the context is MonthsOfyear--Node
MonthName---Attribute
IWDAttributeInfo att=wdContext.nodeMonthsOfYear().getNodeInfo().getAttribute (IPrivateChkView.IMonthsOfYearElement.MONTH_NAME);
IModifiableSimpleValueSet values=att.getModifiableSimpleType().getSVServices().getModifiableSimpleValueSet();
values.put("0","January");
values.put("1","February");
values.put("2","March");
values.put("3","April");
values.put("4","May");
values.put("5","June");
values.put("6","July");
values.put("7","August");
values.put("8","September");
values.put("9","October");
values.put("10","November");
values.put("11","December");
wdContext.nodeMonthsOfYear().addElement(newElement);
and the error is

Hello Abhimanyu L,
Can you show me how to "directly read the index of the check box and its checked and unchecked?
Thanks and WR,
Jane

Read the Javadoc for CheckBoxGroup:
" Data binding:
The context must provide a node X with X.cardinality = 0..n and X.selection = 0..n with an attribute y. The type of y must be a simple type like String. The number of check boxes is the number of node elements, their texts are the values of attribute y, and <b>the selection of the check boxes is determined by the (multiple) selection of the node.</b>
The property texts must be bound to the attribute y. "
To find out the selection, check the selection of the node. See
IWDNode.getLeadSelection()
IWDNode.isMultiSelected(int index)
