How to limit the text and display full text with Read More button in grid view

我尝试过：

What I have tried:

DataTable table=new DataTable();
           //GridView1.DataSource = table;
           string str2 = "select id,title,description from tbl_event order by id desc";
           obj.ds = obj.ret_ds(str2);
           GridView1.DataSource = obj.ds;
           GridView1.DataBind();
           int i = 0;
           foreach (DataRow row in table.Rows)
           {
               string x = row["description"].ToString();
               if (x.Length > 10)
               {
                   GridView1.Rows[i].Cells[0].Text = x.Substring(0, 10) + "<a href=EventDetail.aspx>Read More </a>";
               }
               i++;
               if (i >= table.Rows.Count)
               {
                   return;
               }
           }

但这段代码不起作用。

But this code is not working.

推荐答案

好吧，你必须添加TemplateFiled（gridview的另一列）。有关详细信息，请参阅：

Well, you have to add TemplateFiled (another column of gridview). For farther details, please, see:
