Alert Message in Code Behind File

我们平时在开发过程中,需要在后台代码中控制对话框的弹出
比如说,数据保存成功后要提示用户保存成功.
我们一般的做法是
Response.Write("<script>alert('Save successfully.')</script>");

但是如果页面套在MasterPage的一个iframe的话,在后台代码调用上面的语句,
页面的样式就变了.我们可以通过下面的办法来解决

using System;
2 Alert Message in Code Behind File

using System.Data;
3 Alert Message in Code Behind File

using System.Configuration;
4 Alert Message in Code Behind File

using System.Web;
5 Alert Message in Code Behind File

using System.Web.Security;
6 Alert Message in Code Behind File

using System.Web.UI;
7 Alert Message in Code Behind File

using System.Web.UI.WebControls;
8 Alert Message in Code Behind File

using System.Web.UI.WebControls.WebParts;
9 Alert Message in Code Behind File

using System.Web.UI.HtmlControls;
10 Alert Message in Code Behind File

using System.Text;
11 Alert Message in Code Behind File

我们在调用的时候只要新建一个Alert的实例,然后调用ShowMessage方法就可以
Alert alert = new Alert();
alert.Show("Save successfully.");
