单击GridView的某一行 根据此行id得到这行的所有信息

1.在源的第一行<%@ Page ....%>中添加 EnableEventValidation="false"
2.注意项：若根据id得到点击行的详细信息 则id必须存在GridView中，用隐藏控件接收id的值 如图

3.在GridView1_RowDataBound事件中写入行的onclick事件
 protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
    {
        if (e.Row.RowType == DataControlRowType.DataRow)
        {
            e.Row.Cells[3].Text = e.Row.Cells[3].Text.ToString().Substring(0, 8) + "......";
            ((LinkButton)e.Row.Cells[6].Controls[0]).Attributes.Add("onclick", "return confirm('是否要删除此

行？')");
            e.Row.Attributes["OnClick"] =ClientScript.GetPostBackEventReference(e.Row.Parent.Parent, "Select$" +

e.Row.RowIndex);
            //e.Row.Attributes.Add("onclick", "t=this.style.backgroundColor;this.style.backgroundColor='#ebebce'");
            //e.Row.Attributes.Add("onMouseOut", "this.style.backgroundColor=t");
            //e.Row.Attributes.CssStyle.Add("cursor", "hand");

        }
    }
4.在GridView1_SelectedIndexChanged中写点击行的代码
  protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
    {
        GridView grv = (GridView)sender;
        if (grv.SelectedRow.RowType == DataControlRowType.DataRow)
        {
            if (grv.SelectedIndex != -1)
            {
                int id =Convert.ToInt32(((HiddenField)grv.Rows[grv.SelectedIndex].FindControl("idd")).Value.ToString());
                DataSet ds = op.SelectInfo("招聘信息", id);
                DataTable dt = ds.Tables[0];
                TextBox1.Text = dt.Rows[0][0].ToString();
            }
        }
    }
