Extjs Ext.net行编辑旧值和新值

基于此，我尝试从编辑的行/单元格中获取新旧值。但总是行索引为空。我怎样才能得到这个值？还有另一种方法可以在服务器端捕获这些信息吗

这是我的表格。谢谢

问题解决了。归功于

我只是更改了这段代码：

<Plugins>
            <ext:RowEditing runat="server">
                <Listeners>
                    <BeforeEdit Handler="this.oldValues = Ext.net.clone(e.record.data);" />
                </Listeners>
                <DirectEvents>
                    <Edit OnEvent="OnAfterEdit">
                        <ExtraParams>
                            <ext:Parameter Name="old" Value="this.oldValues" Mode="Raw" Encode="true" />
                            <ext:Parameter Name="new" Value="e.record.data" Mode="Raw" Encode="true" />
                        </ExtraParams>
