public partial class ClientCallbacks : System.Web.UI.Page, ICallbackEventHandler 
{
   protected string txtInfo; 
    protected void Page_Load(object sender, EventArgs e)
    {
        //动态注册JavaScript 
        String cbReference = Page.ClientScript.GetCallbackEventReference(this, "arg", "ReceiveServerData", "context");
        String callbackScript;
        callbackScript = "function CallServer(arg, context)" + "{ " + cbReference + ";}";
        Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "CallServer", callbackScript, true);
    }
    //引发Callback事件处理 
    public void RaiseCallbackEvent(string txtFirstName)
    {
        this.txtInfo = "引发Callback事件处理";        
    }
    //返回Callback结果 
    public string GetCallbackResult()
    {
        return txtInfo;  
    } }
function ReceiveServerData(txtInfo) 
    {     } 
ICallbackEventHandler
