asp.net中GridView编辑,更新,合计用法示例

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    GridViewRow gr = e.Row;
    if (gr.RowType == DataControlRowType.DataRow)
    {
      HiddenField hdnysYear = (HiddenField)e.Row.FindControl("hdnysYear");

      HiddenField hdnChildFlag = (HiddenField)e.Row.FindControl("hdnChildFlag");
      HyperLink hy = (HyperLink)e.Row.FindControl("Hyp_gsName");
      if (hdnChildFlag.Value!="1")
      {
      //设置连接地址\参数
        hy.NavigateUrl = "ys_edit_right.aspx&＃63;gsHkrno=" + hdngsHkrno.Value + "&sysObjNo=" + sysObjNo + "&ysYear=" + hdnysYear.Value;
        hy.Font.Underline = true;
        hy.ForeColor = System.Drawing.Color.Blue;
