I think that simplest way is call refresh whole table after selecting some button:
grid.getView().refresh(false);
But you also need to update your model. When You click on radio button you may set value to your model like^
data.setEvalueation(int selectedRadio);
Or You can create specified ValueProvider
to Evaluation column
ColumnConfig<Data,String> evaluationColumn = new ColumnConfig<Data, String>(new ValueProvider<Data>() {
@Override
public String getValue(Data o) {
String value = o.getRadioColumnValue();
return value;
}
@Override
public void setValue(Data o, Data o2) {
}
@Override
public String getPath() {
return "evaluation";
}
});
