GridView使用技巧之：如何只绑定特定长度的文本？

 <asp:TemplateField HeaderText="规则标题">
                        <ItemStyle HorizontalAlign="Left" VerticalAlign="Middle" CssClass="grid1" Height="20px" />
                        <ItemTemplate>
                            <asp:HyperLink ID="HyperLink1" runat="server" NavigateUrl='<%# Eval("HtmlPath") %>' ToolTip='<%...# Eval("RuleTitle")%>'
                                Text='<%# Eval("RuleTitle").ToString().Length>16?Eval("RuleTitle").ToString().Substring(0,16)+"...":Eval("RuleTitle") %>' Font-Bold="True"></asp:HyperLink>
                        </ItemTemplate>
                    </asp:TemplateField>
