repeater中用placeholder控制列隐藏，如何获取placeholder中的控件？

Question

<asp:Repeater ID="rpt_data" runat="server" OnItemDataBound="rpt_onDataBound">
<ItemTemplate>
....
<asp:PlaceHolder runat="server" ID="PlaceHolder1">
                        <td align="center"><asp:Literal ID="ltr_status" runat="server" Text="<%#Eval("status")%>"></asp:Literal></td>
                    </asp:PlaceHolder>
                </tr>
            </ItemTemplate>cs文件中：    protected void rpt_onDataBound(object sender, RepeaterItemEventArgs e)
    {
        if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem || e.Item.ItemType == ListItemType.Header)
        {
                Control c = e.Item.FindControl("PlaceHolder1");
                if (c != null)
                {
                    PlaceHolder p = (PlaceHolder)c;
                    Literal ltr_status = (Literal)e.Item.FindControl("ltr_status");
                    .....
                }
        }
    }Literal ltr_status = (Literal)e.Item.FindControl("ltr_status");
获取不到控件，用p.FindControl("ltr_status");同样返回null，未将对象设置到对象

Answer 1

if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem || e.Item.ItemType == ListItemType.Header)
        {
                Control c = e.Item.FindControl("PlaceHolder1");
                if (c != null)
                {
                    PlaceHolder p = (PlaceHolder)c;
                    foreach(Control c in p.Controls)
                    {
                     if(c is Litera){}
                    }
                }
        }

Answer 2

Header模板里面有 PlaceHolder1吗？？？

Answer 3

if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)

Answer 4

第一个错误是:
Text="<%#Eval("status")%>">
应该是单引号:
Text='<%#Eval("status")%>'>第二个错误,Literal应该在PlaceHolder中找            PlaceHolder p = (PlaceHolder)e.Item.FindControl("PlaceHolder1");
            Literal L = (Literal)p.FindControl("ltr_status");
            string a=L.Text;

Answer 5

asp:Literal不要用空上.
使用asp:label试试.

Answer 6

Literal在PlaceHolder中找也没找到，用wuyq11(人生如梦) 的方法搞定了，结贴
