Repeater 能不能第一条显示图片，其他的不显示图片

如下:
      <asp:Repeater ID="xcztRepeater" runat="server" EnableViewState="false" OnItemCommand="xcztRepeater_ItemCommand">
       <ItemTemplate>
        <table width="200" height="275" border="0" cellpadding="0" cellspacing="0">
          <tr>
            <td style="height: 90px"><div align="center"><img src='<%# DataBinder.Eval(Container.DataItem, "pic").ToString().Trim()%>' width="186" height="72"></div></td>
          </tr>
          <tr>
            <td height="5"></td>
          </tr>
          <tr>
            <td height="180" valign="top">
            <table width="200" border="0" cellspacing="0" cellpadding="0">
              <tr>
                <td width="20" height="20"><div align="center" class="b1">·</div></td>
                <td width="180" height="20"><span class="kuan_01"><a href="nrjs.aspx?id=<%# DataBinder.Eval(Container.DataItem, "info_id").ToString().Trim()%>" target="_blank"><%# len.GetLen(DataBinder.Eval(Container.DataItem,"title").ToString().Trim(),13) %></a></span></td>
              </tr>      
            </table>
            </td>
          </tr>
        </table>
      </ItemTemplate>  
       </asp:Repeater> 第一条的时候显示:
     <table width="200" height="275" border="0" cellpadding="0" cellspacing="0">
          <tr>
            <td style="height: 90px"><div align="center"><img src='<%# DataBinder.Eval(Container.DataItem, "pic").ToString().Trim()%>' width="186" height="72"></div></td>
          </tr>
          <tr>
            <td height="5"></td>
          </tr>
          <tr>
            <td height="180" valign="top">
            <table width="200" border="0" cellspacing="0" cellpadding="0">
              <tr>
                <td width="20" height="20"><div align="center" class="b1">·</div></td>
                <td width="180" height="20"><span class="kuan_01"><a href="nrjs.aspx?id=<%# DataBinder.Eval(Container.DataItem, "info_id").ToString().Trim()%>" target="_blank"><%# len.GetLen(DataBinder.Eval(Container.DataItem,"title").ToString().Trim(),13) %></a></span></td>
              </tr>      
其它条循环这部分:
              <tr>
                <td width="20" height="20"><div align="center" class="b1">·</div></td>
                <td width="180" height="20"><span class="kuan_01"><a href="nrjs.aspx?id=<%# DataBinder.Eval(Container.DataItem, "info_id").ToString().Trim()%>" target="_blank"><%# len.GetLen(DataBinder.Eval(Container.DataItem,"title").ToString().Trim(),13) %></a></span></td>
              </tr>

  1.   

    <%# ((RepeaterItem)Container).ItemIndex == 0?"<img ...":"其他"%>
      

  2.   

    就是根据((RepeaterItem)Container).ItemIndex是否 等于0来输出不同的html
      

  3.   

    protected void Repeater1_ItemDataBound(object sender, RepeaterItemEventArgs e)
    {
        Image img;
        if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
        {
            if (e.Item.ItemIndex == 0)
            {
                img = (Image)e.Item.FindControl("Image1");
                img.Visible = false;
            }
        }
    }
