GWT CELLTABLE：特定行中的所有列值是否都可能恢复为旧值？

Question

Is it possible that all column values from particular row restore to old value ?

|| ID || Dept || Code || RNO || RCode|| .....................................................||ZCode ||
|| 1  ||  CS   || 001  ||  3      ||  030||...................................................||Q1||
|| 2  ||  DS   || 001  ||  5      ||  040||.....................................................||S1 ||

Suppose In above editable grid I changed 1st record ie

|| 1  ||  CS   || 001  ||  3      ||  030||.....................................................||Q1||

changed to

|| 1  ||  BP   || 010  ||  3      ||  003||.....................................................||Q1||

Is there any way to restore old object(row) values instead to clearing cell view data for each column and redraw editable grid.

In Short revert record to old value which is selected by our checkbox (All or selected chkbox only ie selectionModel.isSelected(object) )

My Grid contain (2-N) column so I am asking this question ?

Answer 1

Are you using a data provider to provide data to the CellTable? You could clone the row data before rendering the table (or on edit) and when you needed to revert you could copy items back in to the data provider and call table.redraw();
