大侠们，求求你们了，帮忙详细说一下gridview控件中显示文本的换行方法，不胜感激！

我用一个freetextbox 写一文章  然后提交到数据库  用gridview控件显示出来
可是都是html格式
我参照csdn里面的帖子用了很多的方法搞了四五天还是没能搞定  请大侠给一个详细的处理方法 多谢！！！！
freetextbox中的内容：
 string   xx="2002-03-28";   
 DataTime   dt=System.Convert.ToDateTime(xx);
gridview中显示内容：
string &nbsp; xx="2002-03-28"; &nbsp; <BR>&nbsp; DataTime &nbsp; dt=System.Convert.ToDateTime(xx); 代码：
dataconn.gerconnect();
         
         //string mysql = "insert into t_forum (fchrForumID,fchrForumCaption,fchrFatherID,fchrForumDetail,fchrOperatorID,fbitNoUsed,fdtmDate) values (" + basicInformation.getReBackNum(int.Parse(DetailsView1.Rows[0].Cells[1].Text)).ToString() + ",'" + TextBox3.Text + "', '" + DetailsView1.Rows[0].Cells[1].Text + "','" + TextBox2.Text + "','" + Session["getInID"].ToString() + "',' ','2006-11-08')";
         //string mysql = string.Format("insert into t_forum (fchrForumID,fchrForumCaption,fchrFatherID,fchrForumDetail,fchrOperatorID,fdtmDate,fbitNoUsed) values('{0}','{1}','{2}','{3}','{4}','{5}','{6}')",
         //                           basicInformation.getReBackNum(DetailsView1.Rows[0].Cells[1].Text).ToString(), TextBox3.Text, DetailsView1.Rows[0].Cells[1].Text, TextBox2.Text, Session["getInID"].ToString(), DateTime.Now, ' ');
         string mysql = string.Format("insert into t_forum (fchrForumID,fchrForumCaption,fchrFatherID,fchrForumDetail,fchrOperatorID,fdtmDate) values(@fchrForumID,@fchrForumCaption,@fchrFatherID,@fchrForumDetail,@fchrOperatorID,@fdtmDate)");
         SqlCommand cm = new SqlCommand(mysql, dataconn.connectionsql);
         cm.Parameters.Add("@fchrForumID", SqlDbType.VarChar,50);
         cm.Parameters.Add("@fchrForumCaption", SqlDbType.VarChar, 100);
         cm.Parameters.Add("@fchrFatherID", SqlDbType.VarChar, 50);
         cm.Parameters.Add("@fchrForumDetail", SqlDbType.VarChar, 5000);
         cm.Parameters.Add("@fchrOperatorID", SqlDbType.VarChar, 50);
         cm.Parameters.Add("@fdtmDate", SqlDbType.VarChar,50);
         //cm.Parameters.Add("@fbitNoUsed", SqlDbType.Bit);         cm.Parameters[0].Value=basicInformation.getReBackNum(DetailsView1.Rows[0].Cells[1].Text).ToString();
         cm.Parameters[1].Value = TextBox3.Text;
         cm.Parameters[2].Value = DetailsView1.Rows[0].Cells[1].Text;
         cm.Parameters[3].Value = TextBox2.Text;
         cm.Parameters[4].Value = Session["getInID"].ToString();
         cm.Parameters[5].Value = basicInformation.getTime();
          //cm.Parameters[6].Value = "  ";        
        
        
        //SqlCommand mycmd = new SqlCommand(mysql, dataconn.connectionsql);
         cm.ExecuteNonQuery();
         basicInformation.getUserPark(Session["getInID"].ToString(),4);
         dataconn.disconnect();请大家多多帮忙，不胜感激！！！1
