ATLAS升级为ASP.NET AJAX 1.0时"ScriptManager找不到"问题的解决
目前参加项目是从去年开始的,去年用的ATLAS做了一些东西,今天上面要求升级为AJAX 1.0的版本。
先从微软网站下载了ASP.NET AJAX 1.0(版本号:1.0.61025.0) 以及 3月2日发布的 AjaxControlToolkit (版本号:1.0.10301.0)
接下来就是安装。
先从控制面板卸载以前安装的ATLAS,再执行ASPAJAXExtSetup.msi进行安装,安装过程一切顺利。
工具栏中选择项目的方式先把AjaxControlToolkit那一套东东更新了,准备用确认按钮测试一下。
新建了一个ASP.NET AJAX-Enabled Web Site项目,页面已经自动添加了一个ScriptManager,拖入了一个UpdatePanel,放入一个按钮,再拖了一个ConfirmButtonExtender放在按钮旁边,关联上按钮,写入确认的文本,运行网站。
程序报错:
The control with ID 'UpdatePanel1' requires a ScriptManager on the page. The ScriptManager must appear before any controls that need it.
我怀疑自己的眼睛,ScriptManager 不是已经在页面上了吗?难道'UpdatePanel1'对他视而不见。

又检查了一遍代码,发现页面顶上的声明好像有问题:怎么还会出现ATLAS的字样。再检查项目引用,果然还有一个Microsoft.Web.Atlas.dll在,遂删除,并重新添加最新的ajax扩展的三个dll到项目(文件:AJAXExtensionsToolbox.dll、System.Web.Extensions.dll、System.Web.Extensions.Design.dll 所处路径:C:\Program Files\Microsoft ASP.NET\ASP.NET 2.0 AJAX Extensions\v1.0.61025)
工具栏上再把Microsoft.Web.Atlas的选项去掉,重新添加AJAXExtensionsToolbox.dll的选项。再次放入ScriptManager、UpdatePanel,再次执行程序,一切正常了。耶~~~
