jquery - Async data loading with WCF service with UI capabilities

Question

I'm working on complex user control(with Telerik components). I'm trying to implement following functionality:

1. Typing some text in RadTextBox(let say: "Hello.txt").
2. Clicking on Button "Check".
3. onClientClick for button "Check" will call WCF method with parameters. Let say that this request/response will take more that 10 seconds, meanwhile I'll see loading image near TextBox AND the most important, I can continue to work on other fields.
4. When WCF service responses UI will be updated with the result.

Thanks in advance

让 wcf 调用一个委托，以便它在完成后回调客户端，同时让客户端 UI 继续。有关如何执行此操作的说明，请参阅我的答案。
