使用会话ASP.Net传递值 [英] Passing value using session ASP.Net

问题描述

我对ASP.net相当陌生.我有一个父页面，可以在其中调用弹出窗口.在弹出窗口中，您可以浏览文件夹路径，然后单击确定"按钮将其传递回父页面，在该父页面中，文件夹路径在文本框中显示.我正在尝试使用Session，但无法弄清楚如何将其发布回父页面.这是来自父级的Page_load的代码

Hi,

I am quite new with ASP.net. I have a parent page where it can call a pop-up window. At the pop-up window you can browse for folder path, and click OK button to pass it back to the parent page where the folder path is displayed in a text box. I am trying to use Session but I cannot figure out how to post it back to the parent page. Here is the code from the Page_load of the parent

protected void Page_Load(object sender, EventArgs e)
        {

            if (!IsPostBack)
            {
                'this.txtRaw.Text = ADSclass.filePath.ToString();
            }
        }

这是弹出窗口中的代码

this is the code from the pop-up window

protected void _selectButton_Click(object sender, EventArgs e)
        {
          Session["path"] = this._browseTextBox.Text.ToString();
          ADSclass.filePath = this._browseTextBox.Text.ToString();//this is a public variable that I declared in a class
        }

任何帮助都可以:)

Any help will do :)

推荐答案

为什么可以在使用新窗口的返回值直接使用Session时使用Session.
