FreeTextBox 黏贴时保存失败

  我在aspx 页面里放了一个  FreeTextBox ，如果手输内容时，保存行，如果是复制在别处黏贴的，无缘无故多了很多空格，保存时则失败

  aspx 文件上

  <div style="margin:10px; width:810px; height:240px;">
                            <FTB:FreeTextBox ID="txtCon" runat="server" Width="800" Height="220"></FTB:FreeTextBox>
                        </div>

  cs 代码
    protected void btnSend_Click(object sender, EventArgs e)
    {
        Msg m = new Msg();   // 一个类，用于进行消息的操作

        m.MsgTitle = this.txtTitle.Text;
        m.MsgBody  = this.txtCon.Text;
        m.Sender   = Convert.ToInt32(Session["uid"]);
        m.Receive  = Convert.ToInt32(this.dblcSender.SelectedValue);
        m.RegDate  = Convert.ToDateTime(DateTime.Now.ToShortDateString());

        m.FN1 = null; m.FN2 = null; m.FN3 = null;
        m.FNURL1 = null; m.FNURL2 = null; m.FNURL3 = null;

        if (this.file_1.PostedFile.FileName.Length > 0)
        {
            string fn1 = this.file_1.PostedFile.FileName;
            long fname1 = DateTime.Now.Ticks + 4L;

            m.FN1 = fn1.Substring(fn1.LastIndexOf("\\") + 1);
            m.FNURL1 = "../upload/" + fname1.ToString() + fn1.Substring(fn1.LastIndexOf("."));
            this.file_1.PostedFile.SaveAs(Server.MapPath("../upload") + "\\" + fname1.ToString() + fn1.Substring(fn1.LastIndexOf(".")));
        }

        if (this.file_2.PostedFile.FileName.Length > 0)
        {
            string fn2 = this.file_2.PostedFile.FileName;
            long fname2 = DateTime.Now.Ticks + 5L;

            m.FN2 = fn2.Substring(fn2.LastIndexOf("\\") + 1);
            m.FNURL2 = "../upload/" + fname2.ToString() + fn2.Substring(fn2.LastIndexOf("."));
            this.file_2.PostedFile.SaveAs(Server.MapPath("../upload") + "\\" + fname2.ToString() + fn2.Substring(fn2.LastIndexOf(".")));
        }

        if (this.file_3.PostedFile.FileName.Length > 0)
        {
            string fn3 = this.file_3.PostedFile.FileName;
            long fname3 = DateTime.Now.Ticks + 6L;

            m.FN3 = fn3.Substring(fn3.LastIndexOf("\\") + 1);
            m.FNURL3 = "../upload/" + fname3.ToString() + fn3.Substring(fn3.LastIndexOf("."));
            this.file_3.PostedFile.SaveAs(Server.MapPath("../upload") + "\\" + fname3.ToString() + fn3.Substring(fn3.LastIndexOf(".")));
        }

        if (mbc.saveMsg(m) == 0)
        {
            Response.Write(sbc.alertMsg("保存成功!"));
            Response.Write(sbc.execScript("window.location.href='message.aspx'"));
        }
        else
        {
            Response.Write(sbc.alertMsg("保存失败!"));
        }
    } --------------------编程问答--------------------   我怀疑和cs 代码没有关系，可能是 FreeTextBox 的问题，是不是要对  FreeTextBox 做一些配置啊
--------------------编程问答-------------------- 一般性的粘贴应该是没什么问题的．，．
　如果你的内容是从Word文档里面复制的话，那就有问题．，．
Word本身也是自带有代码的,...

补充：.NET技术 ,  ASP.NET
