无法将Page A TextBox1中的值传递给Page B TextBox2 [英] Unable to pass the value in Page A TextBox1 to Page B TextBox2

问题描述

我正在尝试通过点击页面A上的按钮将我的网页A，textBox1中的内容传递到网页B，textBox2，但未能这样做。



我的代码如下：



Page A



TextBox

< pre lang =xml> < td class = auto-style4 >
< asp：TextBox ID = < span class =code-keyword> TextBox1 runat = server 高度 = 179px < span class =code-attribute> TextMode = MultiLine 宽度 = 282px > < / asp：TextBox >
< / td >

按钮

< asp：按钮ID =Button1Pasterunat =serverPostBackUrl =〜/ PageB.aspx Font-Bold =TrueForeColor =BlackHeight =41pxText =将内容提交到页面BWidth =195pxOnClick =Button1Paste_Click/> 

  protected   void  Button1Paste_Click（ object  sender，EventArgs e）
 {
 
} 

Page B

 <   asp：TextBox     ID   =  TextBox2    runat   =  server   高度  =  150px    TextMode   =  MultiLine   宽度  =  240px >  <   / asp：TextBox  >  

 受保护  void  Page_Load（ object  sender，EventArgs e）
 {
 
 TextBox2 =（TextBox）（PreviousPage.FindControl （  PageA））; 
 
} 

页面A中的内容未能传递给页面B，任何人都可以帮助建议解决这个问题的方法？谢谢！
