Devexpress ASPxCallback 客户端 e.Result 未定义
我调用 cb.PerformCallback(); 它看起来工作正常，但我无法获得 e.result。 它警告“未定义”。
我可以看到“开始”和“结束”警报。
ASPxCallback cb = new ASPxCallback();
cb.ID = cb.ClientInstanceName = "cb";
cb.ClientSideEvents.BeginCallback = @"function (s,e) { alert('started'); alert(e.result); }";
cb.ClientSideEvents.EndCallback = @"function (s,e) { alert('ended'); alert(e.result); }";
我怎样才能得到电子结果？
I call cb.PerformCallback(); it looks working correctly but I can not get the e.result.
it alerts "undefined".
I can both see "started" and "ended" alerts.
ASPxCallback cb = new ASPxCallback();
cb.ID = cb.ClientInstanceName = "cb";
cb.ClientSideEvents.BeginCallback = @"function (s,e) { alert('started'); alert(e.result); }";
cb.ClientSideEvents.EndCallback = @"function (s,e) { alert('ended'); alert(e.result); }";
how can I get e.result?

改为处理 ASPxClientCallback.CallbackComplete 事件并使用 e.result 属性（注意字符大小写）：

Handle the ASPxClientCallback.CallbackComplete event instead and use the e.result property (take attention to the character case):
