public void gridview_rowcomman(object sender,EventAge e)
{
        GridView grid = (GridView)e.CommandSource;
        Label lblFID = (Label)grid.Rows[Convert.ToInt32(e.CommandArgument)].Cells[0].FindControl("lblFID");
        CheckBox check = (CheckBox)grid.Rows[Convert.ToInt32(e.CommandArgument)].Cells[0].FindControl("chkFID");
        if (e.CommandName == "delComman")
        {
            bool flag = false;
            if (check.Checked == true)
            {
                StringBuilder sb = new StringBuilder();
                sb.Remove(0, sb.Length);
                sb.Append(sb.AppendFormat("delete from cf_sys_dic where fid='{0}'", lblFID.Text.Trim()));
                flag = rc.PExcute(sb.ToString());

                if (!flag)
                    ScriptManager.RegisterStartupScript(this, this.GetType(), "delTopic", "alert('对不起删除失败！');", true);
                else
