关于模式窗体关闭后刷新主页面的问题

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

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);

    }
}
