ScriptManager.GetCurrent（页）.IsInAsyncPostBack抛出运行时错误 [英] ScriptManager.GetCurrent ( Page ).IsInAsyncPostBack throws an error at runtime

问题描述

这是一对夫妇，我是卡在什么显然似乎是一个很无聊的问题，我无法前进小时。

it's a couple of hours that I'm stuck on what apparently seems a very silly problem and I cannot move forward.

基本上，如果我尝试评估在任何一个ASP.NET Web窗体页的事件处理程序（即在Page_Load中）以下内容：

Basically if I try to evaluate the following at any of the event handlers of an ASP.NET Web Form Page (ie at Page_Load):

ScriptManager.GetCurrent ( Page ).IsInAsyncPostBack

我总是得到以下错误：

I always get the following error:

System.Web.UI.IScriptManager'不包含'GetCurrent'，没有扩展方法'GetCurrent接受型System.Web.UI.IScriptManager'的第一个参数的定义可以找到（是否缺少使用指令或程序集引用？）

'System.Web.UI.IScriptManager' does not contain a definition for 'GetCurrent' and no extension method 'GetCurrent' accepting a first argument of type 'System.Web.UI.IScriptManager' could be found (are you missing a using directive or an assembly reference?)

但是，如果我评价相同的任何嵌入的用户控件'事件我得到一个布尔值返回的。

However if I evaluate the same in any of the embedded UserControls' events I do get a boolean value returned.

我失去了一些非常基本的？！

Am I missing something very basic?!

谢谢，

推荐答案

您使用AjaxControlToolkit-的ScriptManager？
我也有问题，有时调试IsInAsyncPostBack值。

Are you using an AjaxControlToolkit-ScriptManager? I had also sometimes problems to debug the IsInAsyncPostBack value.

修改

ScriptManager.GetCurrent(Page).IsInAsyncPostBack

要

AjaxControlToolkit.ToolkitScriptManager.GetCurrent(Page).IsInAsyncPostBack
