C#中的Datalist控件遍历问题

aspx页面中有以下控件：
<asp:TextBox ID="MyBox1" runat="server"></asp:TextBox>
<asp:TextBox ID="MyBox2" runat="server"></asp:TextBox>
<asp:Label ID="Label1" runat="server" Text="Label1"></asp:Label>
<asp:Label ID="Label2" runat="server" Text="Label2"></asp:Label>
<asp:DropDownList ID="DropDownList1" runat="server" Width="100">
<asp:ListItem Value="0">小学</asp:ListItem>
<asp:ListItem Value="1">中学</asp:ListItem>
<asp:ListItem Value="2">大学</asp:ListItem>
</asp:DropDownList>
<asp:DataList ID="dlNews" runat="server" Width="100%">
<ItemTemplate>
<div id="Div1" class="more_line1" runat="server" >联 系 人：<asp:TextBox ID="MyBox5"

runat="server" Text='<%#DataBinder.Eval(Container.DataItem, "username")%>'></asp:TextBox></div>
<div id="Div2" class="more_line1" runat="server" >公司名称：<asp:TextBox ID="MyBox6"

runat="server" Text='<%# DataBinder.Eval(Container.DataItem,"useradd")%>'></asp:TextBox></div>
</ItemTemplate>
</asp:DataList>
通过下面的代码实现了对TextBox，Label，DropDownList中的text或value值的保存。
Session["Allcontrolvalue"] = null;
foreach (Control c in Page.Controls)
{
foreach (Control childc in c.Controls)
{
if (childc.ClientID.IndexOf("MyBox") != -1)
{
if (((TextBox)childc).Text!="")
{ Session["Allcontrolvalue"] = Session["Allcontrolvalue"] + ((TextBox)

childc).Text + ","; }
else
{ Session["Allcontrolvalue"] = Session["Allcontrolvalue"] + "这个为空" + ",";

}

}
if (childc.ClientID.IndexOf("Label") != -1)
{

Session["Allcontrolvalue"] = Session["Allcontrolvalue"] + "标签的值" + ",";
}
if (childc.ClientID.IndexOf("MyButton") != -1)
{
Session["Allcontrolvalue"] = Session["Allcontrolvalue"] + "我的按钮" + ",";
}
if (childc.ClientID.IndexOf("DropDownList") != -1)
{

if (((DropDownList)childc).SelectedValue!=null)
{Session["Allcontrolvalue"] = Session["Allcontrolvalue"] + ((DropDownList)

childc).SelectedItem.Value + ",";}
}
}
}
那么在这段代码中，填写怎样的代码，能实现对DataList中的TextBox的text赋值给Session

["Allcontrolvalue"]？？

Answer 1

foreach(DataItem item in dlNews.Items)
{
TextBox MyBox5=item.FindControl("MyBox5") as TextBox;
Session["Allcontrolvalue"]=Session["Allcontrolvalue"].ToString()+MyBox5.Text;
}

手写的基本就是这个思路。

Answer 2

Session["Allcontrolvalue"] =((TextBox)childc).Text

这样就是对session赋值
