或datalist控件绑定数据,设置两行,更简单
<asp:DataList ID="BizSupply" runat="server" RepeatColumns="2" Width="95%" Height="268">
<ItemTemplate>
<uc1:bizsupply id="BizSupply1" runat="server" ShowType="2" InfoCount="10" DemandTag="[求购]"></uc1:bizsupply>
</ItemTemplate>
<ItemStyle HorizontalAlign="Left" />
</asp:DataList>前台这样写就不显示了~!
<uc1:bizsupply id="BizSupply1" runat="server" ShowType="2" InfoCount="10" DemandTag="[求购]"></uc1:bizsupply>
这样是显示的.不过只有一列,我想显示两列
