DevExpress ASPxGridView 更新的问题


<dx:ASPxGridView ID="grvDetail" ClientInstanceName="grvDetail" runat="server" 
                    Theme="Aqua" Width="970px" AutoGenerateColumns="False"
                    KeyFieldName="Id"
                    onrowupdating="grvDetail_RowUpdating" 
                    onstartrowediting="grvDetail_StartRowEditing" 
                    oncancelrowediting="grvDetail_CancelRowEditing" >
                    <SettingsEditing Mode="Inline" />
                    <Columns>
                        <dx:GridViewDataColumn FieldName="Id" Caption="ID" Visible="false" />
                        <dx:GridViewDataColumn FieldName="ORG_NAME" Caption="组织" VisibleIndex="1" >

                        <dx:GridViewCommandColumn Caption="操作" VisibleIndex="14" Width="28px" EditButton-Visible="true">
                            <EditButton Text="修改" Visible="True">

                            <UpdateButton Text="保存" />
                            <CancelButton Text="取消" />

GridView的数据在后台动态绑定，效果是点击修改，得分变成输入框，点击保存将修改的得分保存到库里面，问题是现在我点击保存并不会调用RowUpdating事件，而直接走CancelRowEditing事件，不知道什么原因，有接触过DEV的高手知道什么原因吗？
