show selected items after filter

the 2 items selected before the filtering are not shown (as selected) in the ListGrid. So the user gets confused because he doesn't know that they are saved externally, so I would like to check them again for him. So that his view is consistent to what he already checked.

I found the forum a way, I write "addDataArrivedHandler" but how could I do this? has anyone ever done this and could help me?

Follow my code

private static ListGrid criaGradeAuxiliares() {  		final ListGrid gridAuxiliares = new ListGrid();  		gridAuxiliares.setDataSource(DataSource.get(Constantes.DS_USUARIO));  		//gridAuxiliares.setAutoFetchData(true);  		gridAuxiliares.setFetchOperation("usuariosFiscalizacao");  		ListGridField colunaNome = FabricaComponentes.criaListGridField(new ConfigListGridField().setNome("nome"));  		ListGridField colunaPerfil = FabricaComponentes.criaListGridField(new ConfigListGridField().setNome("perfil"));  		ListGridField colunaUF = FabricaComponentes.criaListGridField(new ConfigListGridField().setNome("siglaEstado"));  		ListGridField colunaEmpresa = FabricaComponentes.criaListGridField(new ConfigListGridField().setNome("empresaFiscalizadora"));  		gridAuxiliares.setWidth100();  		gridAuxiliares.setHeight(300);  		gridAuxiliares.setFields(colunaNome, colunaPerfil, colunaUF, colunaEmpresa);  		gridAuxiliares.setSelectionType(SelectionStyle.SIMPLE);  		gridAuxiliares.setSelectionAppearance(SelectionAppearance.CHECKBOX);  		gridAuxiliares.setShowFilterEditor(true);  		gridAuxiliares.setFilterOnKeypress(true);  		gridAuxiliares.setFetchDelay(ConstantesVisao.CAMPO_TAM_50);  		gridAuxiliares.setAutoFetchData(true);  	  		return gridAuxiliares;  	}
