无法获取repeater中的值
aspx中
<ItemTemplate>
<tr   bgcolor= "#ffcc66 ">
<td> <%#   DataBinder.Eval(Container,   "DataItem.CustNo ")   %>
<p> <asp:TextBox   ID= "txt "   Runat=server> </asp:TextBox>
<asp:RadioButton   ID= "Radiobutton1 "   Runat= "server "   GroupName= "ff "> </asp:RadioButton> <%#   DataBinder.Eval(Container,   "DataItem.company ")   %>
<p> <asp:RadioButton   ID= "Radiobutton2 "   Runat= "server "   GroupName= "ff "> </asp:RadioButton> <%#   DataBinder.Eval(Container,   "DataItem.City ")   %>
</td>
</tr>
</ItemTemplate>

cs中button的click事件
StringBuilder   builder1=new   StringBuilder();
foreach(RepeaterItem   item1   in   Repeater1.Items)
{
        RadioButton   ck=(RadioButton)item1.FindControl( "Radiobutton1 ");
        if   (ck.Checked) builder1.Append( "A ");
        else
builder1.Append( "B ");
        builder1.Append(((TextBox)item1.FindControl( "txt ")).Text);
}
Response.Write(builder1.ToString());


问题:为什么ck.Checked永远都为false,而且textbox里的值也取不到。
实在找不出错在哪里,请大侠帮看看!
可以通过(RadioButton)item1.FindControl( "Radiobutton1 ")).Checked=true;正常赋值,但就是取不到


------解决方案--------------------
你在Page_Load加载的时候是否进行了IsPostBack的判断?
------解决方案--------------------
IsPostBack
为什么最近那么多人犯此类错误, 回家好好做功课去, 呵呵.
------解决方案--------------------
!IsPostBack
