modalpopup

Short version

All I need is that, in a ModalPopUp, when the DoubleClick event of a ListItem fires, the click event of my OK button should be executed.

Detail

I have a ModalPopUpExtender, which hosts a user control. The user control has an OK and a Cancel button. Along with that, it has a dynamic ListBox added to it. So far, I've considered the following possible solutions:

Use Ajax.Net. But, I cannot afford to have a WebMethod.
Use a ClientScriptCallBack. This will need a lot of JavaScript, since I have made almost every control dynamic.

Is there any other way apart from using an UpdatePanel?
