如何控制Repeater里面的项目？

Question

<table style="width: 850px" class="Tbl_solid" style="background-color: white;" border="0"
                cellspacing="0" cellpadding="0" >
                <asp:Repeater ID="rptList" runat="server">

                            </td>
                        </tr>
                    </ItemTemplate>
                    <FooterTemplate>
                    </FooterTemplate>
                </asp:Repeater>
            </table>

代码大约是这样，我想从后台控制table的某几列的显示和隐藏，但是Repeater里的td的id后台获取不到

Answer 1

添加OnItemDataBound事件获取td进行显示隐藏

 <asp:Repeater ID="rptList" runat="server" OnItemDataBound="TdOp">

    protected void TdOp(object sender, RepeaterItemEventArgs e)
    {
        HtmlTableCell c = e.Item.FindControl("td_KENSYU_MEI_KJ") as HtmlTableCell;
        Response.Write(c == null);
        if (c != null /*&& 你的条件*/) c.Visible = true;
        //....其他的td
    }
