[Solved] Accessing old & new values in ItemUpdated, ItemInserted and ItemDeleted

[Idar Sprock]

Hi,
I would like to see and use the old- and new values of the Items when the following functions are raised:
RadGrid1_ItemInserted(object source, GridInsertedEventArgs e)
RadGrid1_ItemUpdated(object source, GridUpdatedEventArgs e)
RadGrid1_ItemDeleted(object source, GridDeletedEventArgs e)
The reason is that the administrator wants to keep track of all changed data, true an email. By viewing wich data exactly has changed, inserted or Delete (firstName).
(FirstName, LastName, Email, Position,)


Something like this below:

if (Convert.ToString(old_values[key]) != Convert.ToString(new_values[key]))

I found different solutions but didn't quit cover the challenge I encounter:

Thanks,

Found the flollowing solutions:

            Hashtable new_values = new Hashtable();
            Hashtable old_values = new Hashtable();

            GridEditFormItem editedItem = (GridEditFormItem)e.Item;
            e.Item.OwnerTableView.ExtractValuesFromItem(new_values, editedItem);
            old_values = (Hashtable)e.Item.SavedOldValues;

            foreach (Object key in new_values.Keys)
            {
                //if changed
                if (Convert.ToString(old_values[key]) != Convert.ToString(new_values[key]))
                {
                   // Directie[key] = " has changed from '" + Convert.ToString(old_values[key]) + "' to '<font color='#990000'>" + Convert.ToString(new_values[key]) + "</font>'";
                }
            }
