Ext.net行編輯舊值和新值

Question

基於此thread，我試圖從編輯的行/單元中獲取舊值和新值。但總是rowIndex爲空。我怎樣才能得到這個值？還有另外一種方法在服務器端捕獲這些信息？

這是我的網格。謝謝！

<ext:GridPanel runat="server"

它已經解決了。致信@fabricio.murta！

我只是改變這段代碼：

<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> 
        </Edit> 
       </DirectEvents> 
      </ext:RowEditing> 
     </Plugins>
