Hi Anindita,

Take a node say Employee with attribute

id type string

name type string

isChecked type boolean

Try these codes

For criteria 1 : On selection of on toggle button action =====>

-

---

public void onActionEmployeeCheck(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )

{

//@@begin onActionEmployeeCheck(ServerEvent)

int size = wdContext.nodeEmployee().size();

int currentrow = wdContext.nodeEmployee().getLeadSelection();

for(int i=0;i<size;i++)

{

if(i == currentrow)

{

wdContext.nodeEmployee().getEmployeeElementAt(currentrow).setIsChecked(true);

wdComponentAPI.getMessageManager().reportSuccess("ID : "+wdContext.nodeEmployee().getEmployeeElementAt(currentrow).getId());

wdComponentAPI.getMessageManager().reportSuccess("Name : "+wdContext.nodeEmployee().getEmployeeElementAt(currentrow).getName());

}

else

wdContext.nodeEmployee().getEmployeeElementAt(i).setIsChecked(false);

}

//@@end

}

For criteria 2 : On selection of SelectAllRows Button Action====>

public void onActionGetAllRows(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )

{

//@@begin onActionGetAllRows(ServerEvent)

int size = wdContext.nodeEmployee().size();

for(int i=0;i<size;i++)

{

wdContext.nodeEmployee().getEmployeeElementAt(i).setIsChecked(true);

wdComponentAPI.getMessageManager().reportSuccess("ID : "+wdContext.nodeEmployee().getEmployeeElementAt(i).getId());

wdComponentAPI.getMessageManager().reportSuccess("Name : "+wdContext.nodeEmployee().getEmployeeElementAt(i).getName());

Dear Anindita

This is one of limitation in webdynpro handling checkbox is really a mess

Anyway for select all you can give one button and make all checkbox as true.

For Unchecking the 1st checkbox when you click 2nd checkbox, you need to get the row selected and check condition which are checked before selected row.

I don't think so. What do you mean with this?

Hi

I regrete for that.

Actually I took in different manner because I was looking for the Table performance as it takes server round trips when we select the row. So I changed table property to readonly Also I was using the checkbox to tick the row. In this case to do validation was more complex because we cannot get the leadselected. There were 150 fields suppose to do the validations.

The server roundtrip that happens when the lead selection is changed should not be a problem. There are no validations executed. Maybe you had assigne some validating action to the onLeadSelect event?

And this has nothing to do with check boxes.
