前台:<table width="500px">

<table width="500px">

<td width="10" align="left" valign="middle">
<img src="../Images/home0_134.gif" width="7" height="28" />
</td>
<td align="left" valign="middle">
<span class="STYLE8">奥迪</span>

<td width="0" align="right" valign="middle">

<td align="center" style="width: 495px">
<asp:DataList ID="DataList12" runat="server" RepeatColumns="3">
<ItemTemplate>
<a href="TopFull.aspx?NewsId=<%# Eval("NewsId") %>"><%# Eval("Title").ToString()%></a>
</ItemTemplate>
</asp:DataList>

后台:
string sqltext1 = "select Top 6 NewsId,Title from Auto_News where CategorieId=31 and Mark like '%东风本田%' order by NewsDate desc";
DataTable dt1 = SqlHelper.ExecuteDataTable(CommandType.Text,sqltext1,null);
this.DataList12.DataSource = dt1;
this.DataList12.DataBind();
SQL语句没错,数据有返回,程序没错,就是不显示,求高人指点
