如何将子aspx的字符串值传递给父aspx文本框 [英] how to pass string value of child aspx to the parent aspx text box

问题描述

您好我将子aspx页面与父aspx页面链接。当我点击父aspx页面中的按钮时，子aspx页面打开。当我单击子aspx页面中的确定按钮时，它已被关闭没有问题，现在我想将子字符串值从子aspx页面（代码隐藏）传递到父aspx页面文本框



怎么可能？

解决方案

父页面.aspx

 < span class =code-keyword> protected   void  btn_Click（ object  sender，ImageClickEventArgs e ）
 {

 session [value] = value.tosting（）; 
} 

child page.aspx

 string empid = ; 

 受保护  void  Page_Load（ object  sender，EventArgs e）
 {
  if （会话[  value]。ToString（）！=  ）
 {
 empid =会话[  value]。ToString（）; 
 
 label.text = empid.tostring（）; 
} 

} 

您好，试试这个代码..

基于javascript的工作....

session["value"]=value.tosting();
}

child page.aspx

string empid="";

protected void Page_Load(object sender, EventArgs e)
   {
       if (Session["value"].ToString() != "")
       {
           empid = Session["value"].ToString();

label.text=empid.tostring();
       }

}
