AJAX扩展-更新面板问题 [英] AJAX Extentsion - Update Panel Problem

问题描述

我非常喜欢开发可快速响应并立即为用户提供所需内容的Web应用程序，这就是为什么我喜欢使用AJAX ControlToolkit.

但是我意识到当我在UpdatePanel控件中有执行该脚本的按钮时，我无法执行client(javascript)-script.同样，我不能使用FileUpload控件的SaveAs方法附加图片或文档，相反，单击按钮时FileUpload内容(我浏览的文件)将失去它的值.另外，当发生回发时，我使用Calender扩展器的TextBox丢失了其Date值.

有没有解决这个问题的方法?我的意思是向ASP服务器控件添加扩展程序不应阻止它们执行服务器脚本.

请帮助解决此问题.

谢谢.

Hi guy,

I so much love developing web apps that are quick responsive and give users what they want instantly, that is why I love using AJAX ControlToolkit.

But I realize that I cannot execute client(javascript)-script when I have button to execute this script inside an UpdatePanel control. Similarly, I cannot use the SaveAs method of the FileUpload control to attached a picture or document, instead, the FileUpload content (the file I browsed) will lost it value at the click of the button. Also, a TextBox that I use Calender extender for losts it''s Date value when postback occurs.

Is there a way arround solving this problem? I mean adding extenders to ASP server controls should not cease them from executing the server script.

Please help on this issue.

Thanks.

推荐答案

以下是使用AJAX时执行javascript的示例

ScriptManager.RegisterStartupScript(this，this.GetType()，"alertUser"，"alert(``您必须按回车才能继续'');"，true);

将fileupload和textbox + calendar扩展程序放在另一个updatepanel中，以免它们丢失值.

Below is the sample to execute javascript while using AJAX

ScriptManager.RegisterStartupScript(this, this.GetType(), "alertUser", "alert(''You must hit enter to continue'');", true);

Put the fileupload and textbox + calendar extender inside another updatepanel, so that they don''t loose value.
