获取绑定在Repeater中TextBox的值

Question

我在练习用Repeater控件做留言本，所有的空间都是绑定在Repeater里边的。留言本有留言和回复功能，我想在点击确认回复的时候把TextBox的值写入数据库，但现在我不知道如何获取TextBox中的值，望大虾解决。<asp:Repeater ID="Repeater1" runat="server" OnItemCommand="Repeater1_ItemCommand">
        <ItemTemplate>
        <table border=0  cellspacing=0>
            <tr style="color:White;background-color:Green;">
                <td>标题:<%#DataBinder.Eval(Container.DataItem,"cardTit")%> &nbsp&nbsp&nbsp&nbsp&nbsp
                发表时间:<%#DataBinder.Eval(Container.DataItem,"sendTime")%>&nbsp&nbsp&nbsp&nbsp&nbsp
                <asp:LinkButton ID=lbtnSend Text="回复" CommandName="showtext" runat=server></asp:LinkButton>
               </td>
            </tr>
           <tr>
                <td><%#DataBinder.Eval(Container.DataItem,"cardCon")%></td>
           </tr> 
           <tr>              
                <td align=center><asp:TextBox ID="txthuifu" runat=server TextMode=multiline Width="385px" Height="194px" Visible=false></asp:TextBox></td> 
           </tr>  
           <tr>
                <td align=center>
                <asp:LinkButton ID="lbtnhuifu" runat=server Text="提交回复" CommandName="submit" Visible=false OnClick=LinkButton1_Click1></asp:LinkButton>&nbsp&nbsp&nbsp
                <asp:LinkButton ID="lbtnquxiao" runat=server Text="取消回复"  CommandName="qx" Visible=false></asp:LinkButton>
                </td>
           </tr> 
         </table>   
        </ItemTemplate>
        </asp:Repeater>
怎么在后台代码的 protected void Repeater1_ItemCommand(object source, RepeaterCommandEventArgs e)
{
}事件中获取TextBox中的值

Answer 1

{
    TextBox tb = e.Item.FindControl("txthuifu") as TextBox;
    if(tb != null)
    {
        string str = tb.Text;
    }
}

//获取文本框中的值string huifu = ((TextBox)e.Item.FindControls("txthuifu")).Text;
