1.有些时候用到模式弹出窗体，传递参数。根据应用不同，有的需要在弹出框关闭时刷新父页面， 有的不允许刷新父页面。
在这里实现的方式，主要是判断模式窗体返回值，可以直接把值填充到父页面控件中（不刷新），也可以让页面刷新取子页面里的Session值
下面用一个例子说明，有两个页面Default.aspx 和 InputMessage.aspx ,贴代码：
Default.aspx
View Code
Default.aspx.cs
View Code
using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { Label1.Text = "未登录"; if (Session["userid"] != null && Session["username"] != null) { Label1.Text ="<font color='red'>用户编号:"+ Session["userid"].ToString().Trim() + " 用户名:" + Session["username"].ToString()+"</font>"; } } protected void Button1_Click(object sender, EventArgs e) { ScriptManager.RegisterStartupScript(this.Page, this.GetType(), "msg", "var r=window.showModalDialog('inputMessage.aspx',{'name':'张三丰','age':88},'dialogWidth=16; dialogHeight=9;scroll=no; status=no;center=yes'); if (r == undefined) window.location=location;", true); } }
InputMessage.aspx

InputMessage.aspx.cs
View Code
using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; public partial class InputMessage : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { } protected void Button2_Click(object sender, EventArgs e) { string userID = ""; string userName = ""; //验证登录 //登录失败-- 继续 //登录成功-- 保存Session，更新主页面显示用户信息 Session.Add("userid", "111"); Session.Add("username", "小王"); Response.Write("<script language='javascript'>"); Response.Write("window.close()"); Response.Write("</script>"); } }
