三元运算符 在数据绑定中的使用

在使用 datalist 等控件绑定前台数据的时候，有时希望一行只显示定长字符，多出来的部分以省略号代替，我使用三元运算符来做：

<asp:DataList id="DataList1" runat="server" RepeatColumns="5" Width="616px">
                            <ItemTemplate>
                                <table border="0" cellpadding="2" cellspacing="0" align="center" width="100%" height="100%">
                                    <tr>
                                        <td align="center">
                                            <div style="height:10%;width:10%">
                                                <%# DataBinder.Eval(Container.DataItem,"picexplanation").ToString().Length>10?DataBinder.Eval(Container.DataItem,"picexplanation").ToString().Substring(0,10)+"":DataBinder.Eval(Container.DataItem,"picexplanation")%>
                                            </div>
                                        </td>
                                    </tr>
                                    <tr>
                                        <td align="center">
                                            <div style="height:90%;width:90%">
                                                <a href='viewphoto.aspx?imgurl=<%# DataBinder.Eval(Container.DataItem,"primitivepic")%>' target="_blank">
                                                    <IMG height=88 src='../../../../../../upload_pic/userpic_small/<%# DataBinder.Eval(Container.DataItem,"primitivepic")%>' width=88 border=0></a></div>
                                        </td>
                                    </tr>
                                </table>
                            </ItemTemplate>
                        </asp:DataList>

用 Substring(x,x)定你需要显示的长度，而且表格高度都是固定的，这样在首页显示起来比较美观，不至于因为数据过长而导致变形，其实使用 div+css可以做的更好些，但是俺还没有学好那个东西，呵呵。大家有好的办法多多讨论，共同进步
