重金求解
问题：Page页面上有二个Button，一个Panel。其中Button1点击的时候，自动在Panel里添加5个文本框。在生成的5个文本框中输入数值后。 点击另外一个Button时候，弹出刚才输入文本框的值。



[解决办法]
protected void btn1_Click(object sender, EventArgs e)
{
for(int i=0;i<5;i++)
{
TextBox txt = new TextBox();
txt.ID = "txt_" + i.ToString();
Panel1.Controls.Add(txt);
}
}

protected void btn2_Click(object sender, EventArgs e)
{
for(int i=0;i<5;i++)
{
TextBox txt=Panel1.FindControl("txt_" + i.ToString()) as TextBox;
if(txt!=null)
{}
}
}

ClientScript.RegisterStartupScript(this.GetType(), "", "<script language='javascript' defer>alert('" +txt.Text + "');</script>");

因为动态生成的textbox在重新点击按钮后会消失，所以在页面上放置HiddenField1来保存textbox的值

HTML code

        <asp:Button ID="Button1" runat="server" Text="Button" OnClick="Button1_Click" />        <asp:Panel ID="Panel1" runat="server" Height="50px" Width="125px">            </asp:Panel>        <asp:HiddenField ID="HiddenField1" runat="server" />        <asp:Button ID="Button2" runat="server" Text="Button" OnClick="Button2_Click" OnClientClick="saveValue();" /><script>function saveValue(){    var obj=document.getElementById("Panel1").getElementsByTagName("input");    for(var i=0;i<obj.length;i++)   {       if(obj.type="text")                document.getElementById("HiddenField1").value+=obj[i].value+",";   }     alert(document.getElementById("HiddenField1").value)}</script>

我也来凑个热闹,企图获得重金!!
生成一个TextBox,多个依次类推,放一个Hidden1,中间变量

页面html
<asp:Button ID="Button1" runat="server" onclick="Button1_Click" Text="Button" />
<asp:Button ID="Button2" runat="server" onclick="Button2_Click" Text="Button"  OnClientClick="test()" />
<asp:Panel ID="Panel1" runat="server">
</asp:Panel>
<input id="Hidden1" type="hidden"  runat="server" />

js:
<script type="text/javascript">
   function test() {
      document.getElementById("Hidden1").value = document.getElementById("myT1").value;
      }
</script>

c#
   protected void Button1_Click(object sender, EventArgs e)
   {
       this.sText();//动态生成TextBox
   }
   protected void Button2_Click(object sender, EventArgs e)
   {
       ViewState["t1"] = Hidden1.Value.ToString();//获得中间变量
       this.sText();//动态生成TextBox
       ((TextBox)Panel1.FindControl("myT1")).Text = ViewState["t1"].ToString();//赋值
   }

   private void sText()
   {
       TextBox myT1 = new TextBox();
       myT1.ID = "myT1";
       Panel1.Controls.Add(myT1);
   }

探讨

protected void btn1_Click(object sender, EventArgs e) 
 
{
for(int i=0;i <5;i++)
{
TextBox txt = new TextBox();
txt.ID = "txt_" + i.ToString();
Panel1.Controls.Add(txt);
}
}

protected void btn2_Click(object sender, EventArgs e)
{
for(int i=0;i <5;i++)
{
TextBox txt=Panel1.FindControl("txt_" + i.ToString()) as TextBox;
if(txt!=null)
  {}
}
}

引用:
protected void btn1_Click(object sender, EventArgs e)  
{  
for(int i=0;i <5;i++)  
{  
TextBox txt = new TextBox();  
txt.ID = "txt_" + i.ToString();  
Panel1.Controls.Add(txt);  
}  
}  

protected void btn2_Click(object sender, EventArgs e)  
{  
for(int i=0;i <5;i++)  
{  
TextBox txt=Panel1.FindControl("txt_" + i.ToString()) as TextBox;  
if(txt!=null)  
 {}  
}  
}  



修改：  

for(int i=0;i <5;i++)  
{  
TextBox txt=Panel1.FindControl("txt_" + i.ToString()) as TextBox;  
if(txt!=null)  
{  
txt.Text=HiddenField1.Value();//这里是五个隐藏组件，我代表性的写了一个。  
}  
}

4楼应该是对的,因为控件不是在page_load里产生的,所以要注意一个回传的问题.
[解决办法]
 <asp:Panel ID="pnlTest" runat="server">
       <input type="button" id="btnShowButtons" value="显示按钮" onclick="btnShowButtons_Click()" />
       <asp:Button ID="btnShowValues" runat="server" Text="显示文本框值" />
       <div id="ContainerForTXT" style="display:none">
           <asp:TextBox ID="txt1" runat="server" /><br />
           <asp:TextBox ID="txt2" runat="server" /><br />
           <asp:TextBox ID="txt3" runat="server" /><br />
           <asp:TextBox ID="txt4" runat="server" /><br />
           <asp:TextBox ID="txt5" runat="server" />
       </div>   
   </asp:Panel>
   <script>
       function btnShowButtons_Click()
       {
           document.getElementById("ContainerForTXT").style.display="block"
       }
   </script>
5个文本框不是动态的增加的，那最好控制<div>是否隐藏，至于取值弹出显示不难了吧？
