前台
<asp:DataList id="DLTNews" runat="server" Width="185">
<ItemStyle Height="25px"></ItemStyle>
<ItemTemplate>
<a href=‘’../Bulletin/show.aspx?id=<%# DataBinder.Eval(Container.DataItem,"dc_id") %>‘’ target=_blank>
<%=_strLineTitle%><%# DataBinder.Eval(Container.DataItem,"vc_Title") %>
<font class="zt6">
<%# Convert.ToDateTime(DataBinder.Eval(Container.DataItem,"dt_Date")).ToString("[yyyy年MM月dd日]") %>
</font></a>
</ItemTemplate>
</asp:DataList>
调用:
<uc1:Bull id="Bull1" runat="server" IMID="278" IPageSize="5" ILineTitle="<font color=red>◇</font>" IBackColor="#ff0000">
该例子主要演示了web自定义组件的属性定义、负值和使用。
