无法找到回调的目标'__Page'或未实现ICallbackEventHandler。 [英] The target '__Page' for the callback could not be found or did not implement ICallbackEventHandler.

问题描述

我将此代码转换为 [ ^ ]

到vb.net

我有这个问题

在C＃

I converted this Code [^]
to vb.net
and I have this Problem
in C#

ClientScriptManager cm = Page.ClientScript;
          String cbReference = cm.GetCallbackEventReference(this, "arg","ReceiveServerData", "");
          String callbackScript = "function CallServer(arg, context) {" + cbReference + "; }";
          cm.RegisterClientScriptBlock(this.GetType(), "CallServer", callbackScript, true);

我将其转换为vb .net

I converted it to in vb.net

Dim cm As ClientScriptManager = Page.ClientScript
          Dim cbReference As String
          cbReference = cm.GetCallbackEventReference(Me, "arg", "ReceiveServerData", "")
          Dim callbackScript As String = ""
          callbackScript &= "function CallServer(arg, context)" & "{" & cbReference & "; }"
          cm.RegisterClientScriptBlock(Me.GetType(), "CallServer", callbackScript, True)

我有无效的操作异常

cbReference = cm.GetCallbackEventReference（我，arg，ReceiveServerData，）

目标''找不到回调的__Page''或没有实现ICallbackEventHandler。

I have invalid operation exception in
cbReference = cm.GetCallbackEventReference(Me, "arg", "ReceiveServerData", "")
The target ''__Page'' for the callback could not be found or did not implement ICallbackEventHandler.
