GWT column sort handler ,how to get column's value which has been selected

Question

I have a celltable in GWT and want to implement sorting functionality on it , from database(Criteria) for that i just want to know how to get the value of the column which has been clicked for sorting

here is my code

            ctJobs.addColumnSortHandler(new ColumnSortEvent.Handler() {
            public void onColumnSort(ColumnSortEvent event) { 
            event.getColumn();
            event.getColumn().getValue("what do we need to write here ???");

from event.getColumn() , i am getting column in the form of object

com.google.gwt.cell.client.ClickableTextCell@188a12e

I want to know the the column's name / value for that i am trying event.getcolumn().getvalue("??"); but what is the parameter for that, or is there any other way of getting column's name which has been clicked.

Thanks

Answer 1

Are you using a ListDataProvider or an AsyncDataProvider for your cell table?

In case of an AsyncDataProvider the sorting must be done on the server side, so there is no need to add a ColumnSortHandler.

Please see the GWT docs.

To get the name of the column clicked for sorting see this question.
