Javascript Obout grid OnClient CallbackError未显示警报消息

我在应用程序中使用了Obout网格。我已经在它上面设置了客户端事件，所有其他客户端事件都工作得很好，除了：OnClientCallbackError。我在服务器端有一个方法，在执行删除之前在数据库端验证删除。下面是它的代码：

protected void DeleteRecord(object sender, GridRecordEventArgs e)
        {
            //check if the record is not used in any other relationship
            var id = Convert.ToInt32(e.Record["ID"].ToString());
            var result =_areaRepository.RelationshipCheck("env_Area", id);
            var desc = e.Record["Description"].ToString();
        string message;
            if(result <= 0)
            {
                //show error message
                _areaRepository.UpdateArea(id, desc, true);
               }
            else
            {
                message = "Record cannot be  deleted";
               throw new Exception(message);
            }
        }

在网格的客户端事件中，您有：

<ClientSideEvents ExposeSender="True" OnClientAdd="OnAdd" OnClientEdit="OnEdit" OnClientCallbackError="onCallbackError" />

警报消息必须显示为没有问题，但我的消息不起作用。 我已从代码中删除更新面板。我的母版页上有一个脚本管理器，看起来像：

<asp:ScriptManager ID="ScriptManager1" runat="server" ScriptMode="Release" EnablePageMethods="True" EnablePartialRendering="True">
  </asp:ScriptManager>

我们已经买了奥波特套房。我已经向Obout支持者提出了同样的问题，但他们在整整一周后都没有回复我。当我运行应用程序时，我看到错误被抛出，我的应用程序被压碎。网格的代码为：

您能否与此事件共享用于定义obout网格的html。我已修改了问题并在其中添加了代码。
