如果字数过长就显示 "...."

Question

<asp:Repeater ID="RepeaterList" runat="server">
                        <ItemTemplate>
                            <table width="410" border="0" align="center" cellpadding="0" cellspacing="0">
                                <tr>
                                    <td width="380" id="q_title">
                                        <strong>◆ <a href="QuestionDetail.aspx?questionid=<%#Eval("question_id")%>&gid=<%#Eval("category_group_id")%>">
                                            <%#Eval("question_title") %></strong> </a>
                                    </td>
                                </tr>
                                <tr>
                                    <td id="q_content">
                                        <br /><strong>
                                            <asp:Label ID="lblQuestion_content" runat="server" Text="答案:"></asp:Label></strong><asp:Label ID="lblContent" truncateToFit="true" maxWidth="25" runat="server" ForeColor="Gray" Text='<%#Eval("answer_content") %>'></asp:Label>
                                    </td>
                                </tr>
                                <tr>
                                    <td width="375">
                                        <hr />
                                    </td>
                                </tr>
                            </table>
                        </ItemTemplate>
                    </asp:Repeater>我的repeater绑定table了，一个问题和一个答案显示如下：
◆ 为什么问题这么多 
答案:没有最好，但求更好！
————————————
◆ 为什么  
答案:为什么的答案  
————————————
◆ 为什么1 
答案:为什么1的答案  
....加入有一个问题的答案 结果N长...他也会全部显示出来这样影响美观加入答案字数到了20个就显示20个，后面就显示...效果如下：
ssfdadfsdfs...

Answer 1

 protected string CutString(string str, int len, string word)
        {
            if (str == null || str.Trim() == "")
            {
                return "";
            }
            if (str.Length < len)
            {
                return str;
            }
            StringBuilder sb = new StringBuilder();//新字符串
            sb.Append(str.Substring(0, len));
            if (word.Trim() != "")
            {
                sb.Append(word);
            }
            return sb.ToString();
        }

Answer 2

StringBuilder 是社么意思啊？是不是需要引用什么？ Using之类的...？

Answer 3

1.table-layout:fixed;/* 只有定义了表格的布局算法为fixed，下面td的定义才能起作用。 */   
2.word-break:keep-all;/* 不换行 */   
3.white-space:nowrap;/* 不换行 */   
4.overflow:hidden;/* 内容超出宽度时隐藏超出部分的内容 */   
5.text-overflow:ellipsis;/* 当对象内文本溢出时显示省略标记(...) ；需与overflow:hidden;一起使用。*/  其实没必要一定要20个字就省略 你只要把一个DIV的宽度写死  然后加上 上面的样式。就OK。

Answer 4

text-overflow:ellipsis;word-break:keep-all;word-warp:warp;white-space:nowrap;

Answer 5

public string CutStr(string str)
    {
        if (str.Length > 20)
        {
            return str.Substring(0, 20) + "....";
        }
        else
        {
            return str;
        }
    }<%# CutStr(Eval("question_title").ToString()) %>

Answer 6

        protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
        {
            if (e.Row.RowType == DataControlRowType.DataRow)
            {
                e.Row.Cells[2].ToolTip = e.Row.Cells[2].Text;
                if (e.Row.Cells[2].Text.Length > 50)
                {
                    e.Row.Cells[2].Text = e.Row.Cells[2].Text.Substring(0, 49) + "... ";
                }
            }
        }以前写gridview时用的,稍微改下应该就行了

Answer 7

    <%#Eval("dis_content").ToString().Length>25?((Eval("dis_content")).ToString().Substring(0,25))+"…":
                                                     ((Eval("dis_content")).ToString())   
                                                      
                                                                                %>

Answer 8

其实有这一段就可以了 上面是复制的- -!!overflow:hidden;text-overflow:ellipsis 

Answer 9

td里面加个div标签，div里面加style="width:100px; overflow:hidden; text-overflow:ellipsis; white-space:nowrap;"具体的宽度自己调

Answer 10

<td id="q_content" style="text-overflow:ellipsis;word-break:keep-all;word-warp:warp;white-space:nowrap;">你的内容</td>
