求助，动态设置iframe的src,不显示
aspx页面代码

C# code

<iframe id="Reply" width="100%" runat="server" scrolling="yes" src="<%=GetSrc() %>" ></iframe>

cs文件代码

C# code

    protected void ShowReply(object sender, EventArgs e)    {        //Panel1.Attributes.Add("style", "display:none");        string url = "ShowEmailDetails.aspx?ID=" +_id ;        Reply.Attributes.Add("src", url);    }

我想单击按钮时设置iframe的src属性，但是iframe中的网页并没有显示，求高人指教

照你的写的代码，你可以拷贝测试，你看看每次的url变了吗？


C# code<%@ Page Language="C#"  %><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><script runat="server">  private String _id = "";  protected void ShowReply(object sender, EventArgs e)  {    _id = Guid.NewGuid().ToString();    string url = "ShowEmailDetails.aspx?ID=" + _id;    Reply.Attributes.Add("src", url);  }  protected void Page_Load(object sender, EventArgs e)  {    if (!Page.IsPostBack)    {      Reply.Attributes.Add("src", "ShowEmailDetails.aspx");    }  }</script><html xmlns="http://www.w3.org/1999/xhtml"><head id="Head1" runat="server">  <title></title></head><body>  <form runat="server" id="form1">  <iframe id="Reply" width="100%" runat="server" scrolling="yes"></iframe>  <asp:Button ID="Button1" runat="server" onclick="ShowReply" Text="改变" />  </form></body></html>

本来javascript可以轻松解决的问题,非要回发到后台,由asp.net来折腾
[解决办法]
window.mainFrm.location = urlStr;  //兼容IE FF
