方法一：

protected void gv_RowCommand(object sender, GridViewCommandEventArgs e)
    {       
        if (e.CommandName == "Insert")
        {
            if (gv.Rows.Count > 0)
            {
                try
                {
                    string thing = ((TextBox)gv.FooterRow.FindControl("txtFthings")).Text;
                    int result = dam.InsertwGCDSJ(thing, Convert.ToInt32(this.DropDownList1.SelectedValue), 0);
                    if (result > 0)
                    {
                        this.gv.FooterRow.Visible = false;
                        BindData();
                    }
                    else
                    { message_Show("添加失败!"); }

}
                catch { }
            }
            else

                Table gvTable = ((Table)gv.Controls[0]);
                string netThing = ((TextBox)gvTable.Rows[0].FindControl("txtNewThing")).Text;
