asp.net页面弹出对话框

一、Response.Write的方式
            
           Response.Write("<script language='javascript'>window.dialogArguments.loginInfo.location.reload();window.close(this);</script>");

           但会影响页面的样式控制；

二、Page.RegisterStartupScript方法

            Page.RegisterStartupScript("", "<script language=javascript>alert('你的没有登录！请登录！！');window.showModalDialog('LoginForm.aspx',parent,'dialogWidth:400px;dialogHeight:300px;center:yes;status:no;scroll:yes;help:no;');</script>");

           Page.RegisterStartupScript("message", "<script language='javascript' defer>alert('" + msg.ToString() + "');</script>");

            
            /// 显示消息提示对话框，并进行页面跳转
        /// </summary>
        /// <param name="page">当前页面指针，一般为this</param>
        /// <param name="msg">提示信息</param>
        /// <param name="url">跳转的目标URL</param>
        public static void ShowAndRedirect(System.Web.UI.Page page, string msg, string url)
        {
            StringBuilder Builder = new StringBuilder();
            Builder.Append("<script language='javascript' defer>");
            Builder.AppendFormat("alert('{0}');", msg);
            Builder.AppendFormat("top.location.href='{0}'", url);
            Builder.Append("</script>");
            Page.RegisterStartupScript("message", Builder.ToString());

        }


         Page.RegisterStartupScript("","<script>if(confirm(＇注册成功,请登陆!＇)){window.open(＇index.aspx＇,＇_self＇);}</script>");

         RegisterClientScriptBlock("","<script>alert(＇所要弹出的提示信息＇);</script>");
