1.首先拖一个ＧridView到窗体，并选择数据源，然后配属性Colums如下图：

2.对它事件写代码如下：

 protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)     {         GridView _gridView = (GridView)sender;         int _selectedIndex = int.Parse(e.CommandArgument.ToString());         string _commandName = e.CommandName;         if (_commandName == "DownLoad")         {             if (_gridView.SelectedIndex > -1)             {                 _gridView.SelectedRow.ForeColor = System.Drawing.Color.Black;             }             _gridView.SelectedIndex = _selectedIndex;             _gridView.SelectedRow.ForeColor = System.Drawing.Color.Red;         }

    }     protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)     {         if (e.Row.RowType == DataControlRowType.DataRow)         {             LinkButton _singleClickButton = (LinkButton)e.Row.Cells[0].Controls[0];             string _jsSingle = ClientScript.GetPostBackClientHyperlink(_singleClickButton, "");             e.Row.Attributes["Onclick"] = _jsSingle;

        }     }

3.重写  Render(HtmlTextWriter writer) protected override void Render(HtmlTextWriter writer)     {         // The client scripts for GridView1 were created in GridView1_RowDataBound         foreach (GridViewRow r in GridView1.Rows)         {             if (r.RowType == DataControlRowType.DataRow)             {                 Page.ClientScript.RegisterForEventValidation(r.UniqueID + "$ctl00");                 Page.ClientScript.RegisterForEventValidation(r.UniqueID + "$ctl01");                 Page.ClientScript.RegisterForEventValidation(r.UniqueID + "$ctl02");             }         }

        base.Render(writer);     }
