在GridView中，設置字符超出單元格部分的內容用“...”表示，代碼如下：

<asp:TemplateField HeaderText="用途" SortExpression="USE_FOR">
           <ItemTemplate>
                      <div style="width: 100px; overflow: hidden; text-overflow: ellipsis; white-space: nowrap; text-decoration: none" title='<%# Eval("USE_FOR")%>'>
                               <asp:Label ID="lblUSE_FOR" runat="server" Text='<%# Bind("USE_FOR")%>'></asp:Label>
                       </div>
           </ItemTemplate>
 </asp:TemplateField>
