我要求在移动下一页时登录用户并在弹出窗口中显示登录消息。我的登录是在母版页上..

//登录页面上的代码

I am asking for login to user while moving next page and showing message for login on popup. my login is on master page..
//code on login page

if (!string.IsNullOrEmpty(Request.QueryString["ReturnUrl"]))
        {
       
            //Response.Write(retrnurl);
            string retrnurl = Request.QueryString["ReturnUrl"].ToString();
            retrnurl = "product_title.aspx";
            Response.Redirect(retrnurl,true);

        }

推荐答案

相反你可以写这样的



Request.UrlReferrer返回上一页url。将其保存在视图状态。

Instead u can write like this

Request.UrlReferrer returns the previous page url.Save it in view state.

Dim str As String = Convert.ToString(Request.UrlReferrer)
           ViewState("PreviousPage") = str

WHENEEVER你想回去

WHENEEVER U WANT TO Go Back

Dim str As String = Convert.ToString(ViewState("PreviousPage"))
        Response.Redirect(str)
