Hello ahmed salah,

Thank you for posting in our forum.

It appears that you’re currently not using an igGrid for displaying and editing your data.

If you’d like to use the igGrid control for editing your data you can refer to the following example that showcases the functionality and different options available:

http://www.igniteui.com/grid/editing-api-events

If you’d like to cancel the value change for a specific column in a igGrid you can use the editCellEnding event that the grid provides:

http://www.igniteui.com/help/api/2016.1/ui.iggridupdating#events:editCellEnding

The event arguments provide both the current edited value (ui.value) and the old value (ui.oldValue).

Let me know if you have any question in regard to the igGrid.

Best Regards,

Maya Kirova
