Gridview控件中字符串的截取【转】

在GridView控件里，比如说新闻标题过长，需要对字符串进行规定的截取，并用"..."补在后面，经常要用到。    

 

 1 <asp:GridView ID="GridView1"  runat="server" Width="96%" CellPadding="4" ForeColor="#333333" AutoGenerateColumns="False" OnSelectedIndexChanged="GridView1_SelectedIndexChanged" ShowHeader="False" GridLines="None">
 2                             <FooterStyle BackColor="#507CD1" Font-Bold="True" ForeColor="White" />
 3         <Columns>
 4             <asp:TemplateField>
 5                 <ItemTemplate>
 6                    &nbsp;&nbsp;&nbsp;·
 7                 </ItemTemplate>
 8                 <HeaderStyle Width="10%" />
 9                 <ItemStyle Width="10%" />
10             </asp:TemplateField>
11             <asp:TemplateField>
12                 <ItemTemplate>
13                    <asp:HyperLink ID="HyperLink1" runat="server" Target="_blank" Text='<%# Eval( "n_title ").ToString().Length> 16?(Eval( "n_title ").ToString().Substring(0,16)+ " "):Eval( "n_title ") %>' NavigateUrl='<%# DataBinder.Eval(Container,"DataItem.n_id","showNews.aspx?n_id={0}") %>' ></asp:HyperLink>
14                 </ItemTemplate>
15                 <HeaderStyle Width="70%" />
16                 <ItemStyle Width="70%" />
17             </asp:TemplateField>
18             <asp:BoundField DataField="n_intime" DataFormatString="『{0:MM.dd}』" HtmlEncode="False" >
19                 <HeaderStyle Width="20%" />
20                 <ItemStyle Width="20%" />
21             </asp:BoundField>
22         </Columns>
23         </asp:GridView>
