两个一维数组处理要删除的资料：可以扩展为一个二维数组。
string[] ms_CheckDataPK_Group = ms_CheckDataPK.Split(';');
if (ms_CheckDataPK_Group.Length != 0)
{
                for (int i = 0; i < ms_CheckDataPK_Group.Length; i++)
                {
                    string[] mo_PM048TB_Data = ms_CheckDataPK_Group[i].Split(',');
                    mo_PM048TB.TASK_CODE = mo_PM048TB_Data[0].Trim().ToString();
                    if (!mo_PM048TB_Data[1].Trim().ToString().Equals(""))
                        mo_PM048TB.LOG_DATE = Convert.ToDateTime(mo_PM048TB_Data[1].Trim().ToString());
                    mo_PM048TB.USER_CODE = mo_PM048TB_Data[2].Trim().ToString();
                    mo_PM048TB.TASK_KIND = mo_PM048TB_Data[3].Trim().ToString();
                    mo_BLLPM048TB.Delete(mo_PM048TB);
                }
}

AJAX的使用函数：
        private void Query(string s_aUserCode)
        {

            PMUC01 o_PMUC01 = new PMUC01();
            DataSet o_ds = new DataSet();
            string s_UserName = string.Empty;
            try
            {
                o_ds = o_PMUC01.Query(Request["UserCode"].ToString());

                if (o_ds != null && o_ds.Tables[0].Rows.Count > 0)
                {
                    s_UserName = o_ds.Tables[0].Rows[0]["USER_CHNAME"].ToString();
                }
                else
                {
                    s_UserName = "";
                }
                Response.Clear();
                Response.Write(s_UserName);
                Response.Flush();
                Response.Close();
            }
            catch (Exception ex)
            {
                ex.Message.ToString();
            }
        }
//Ajax的JS：
function GetNameById(obj)
{
    LeachInputChinese();
    var userCode=obj.value;
    if(userCode=="")
    {
        return true;
    }
    else
    {
        var reqURL = 'PMTM02Q.aspx?UserCode=' + userCode;
        var oHttpReq = GetXmlHttpRequest();
        oHttpReq.open("POST",reqURL,false);
        oHttpReq.send("");
        var result = oHttpReq.responseText;
        document.getElementById("ctl00_cphPage_txtUSER_CHNAME").value=result;
    }
}

导出Excel的代码：
private bool ExportExcel()
{
            try
            {

                Response.ClearContent();
                Response.Charset = "UTF8";
                Response.AddHeader("content-disposition", "attachment; filename=PMTM02.xls");
                Response.ContentType = "application/excel";
                Response.ContentEncoding = System.Text.Encoding.UTF7;
                StringWriter o_sw = new StringWriter();
                HtmlTextWriter o_htw = new HtmlTextWriter(o_sw);
                GridView o_GridView = new GridView();
                o_GridView = this.grvQuery;
                o_GridView.RowDataBound += new GridViewRowEventHandler(o_GridView_RowDataBound);
                o_GridView.DataSource = (DataTable)ViewState["DT"];
                o_GridView.AllowPaging = false;
                o_GridView.DataBind();
                o_GridView.RenderControl(o_htw);
                Response.Write(o_sw.ToString());
                Response.End();
                return true;
            }
            catch (Exception ex)
            {
                ex.Message.ToString();
                return false;
            }
}
override一个事件，导出Excel所需的:
#region VerifyRenderingInServerForm
        /// <summary>
        /// VerifyRenderingInServerForm
        /// </summary>
        /// <param name="control"></param>
        public override void VerifyRenderingInServerForm(Control control)
        {
            //
        }
#endregion

加入EnableEventValidation="false"  :
例：<%@ Page Language="C#" MasterPageFile="~/MasterPage.master" AutoEventWireup="true"
    CodeFile="PMTM02Q.aspx.cs" EnableEventValidation="false"

设置Grv的某列显示为隐藏：
        protected void o_GridView_RowDataBound(object sender, GridViewRowEventArgs e)
        {
            e.Row.Cells[0].Visible = false;
            e.Row.Cells[1].Visible = false;
        }

ArrayList的使用:
ArrayList a_Authority = ((Auth)Session["AUTH"]).chkAuthority("PMTM02Q");
for (int i = 0; i < a_Authority.Count; i++)
{
                if (a_Authority[i].ToString().Equals(Authority.SELECT.ToString()))
                    this.ibtQuery.Visible = false;
}

Server,Context:
            this.Context.Items.Add("FromPage", "PMTM02Q");
            Server.Transfer("PMTM02M.aspx");

查找CheckBox的控件：
CheckBox o_CheckData = new CheckBox();
o_CheckData = (CheckBox)grvQuery.Rows[i_Check].FindControl("chkHit");

删除事件：并接要删除的资料，删除动作，删除后再查询
            for (int i_Check = 0; i_Check < grvQuery.Rows.Count; i_Check++)
            {
                CheckBox o_CheckData = new CheckBox();
                o_CheckData = (CheckBox)grvQuery.Rows[i_Check].FindControl("chkHit");
                if (o_CheckData.Checked)
                {
                    ms_CheckDataPK += ((Label)grvQuery.Rows[i_Check].Cells[4].FindControl("lblTASK_CODE")).Text.Trim() + ","
                        + ((Label)grvQuery.Rows[i_Check].Cells[10].FindControl("lblLOG_DATE")).Text.Trim() + ","
                        + ((Label)grvQuery.Rows[i_Check].Cells[15].FindControl("lblUSER_CODE")).Text.Trim() + ","
                        + ((Label)grvQuery.Rows[i_Check].Cells[16].FindControl("lblTASK_KIND")).Text.Trim() + ";";//TxRefNo 2 3 4 15
                }
            }
            ms_CheckDataPK = ms_CheckDataPK.Substring(0, ms_CheckDataPK.Length - 1);
            if (isDelete(ms_CheckDataPK))
            {
                AlertMessage1.AddOkMsg(Resources.WebResource.S018);
            }
            else
            {
                AlertMessage1.AddOkMsg(Resources.WebResource.S019);
            }
            //
            Query(false);

grvQuery_RowCommand的事件：
if (e.CommandName == "imgbtn")
{
ImageButton imgIndex = (ImageButton)(e.CommandSource);
mo_PM048TB.TASK_CODE = ((Label)imgIndex.FindControl("lblTASK_CODE")).Text.Trim();
this.Context.Items.Add("Action", "UPD");
this.Server.Transfer("PMTM02M.aspx");
}

PMTM02M:
更新事件：
private Boolean isUpdate(Model.PM048TB mo_PM048TB)
{
            try
            {
                mo_BLLPM048TB.Update(mo_PM048TB);
                return true;
            }
            catch
            {
                return false;
            }

}

遍历rdiobuttonlist内的Items：
if (ViewState["Action"].ToString().Equals("UPD") && (!ViewState["RadioPROGR_CODE"].Equals("")))
{
                    for (int i = 0; i < rdolstPROGR_CODE.Items.Count; i++)
                    {
                        if (rdolstPROGR_CODE.Items[i].Text.Trim().ToUpper().Equals(ViewState["RadioPROGR_CODE"].ToString().Trim().ToUpper()))
                            rdolstPROGR_CODE.Items[i].Selected = true;
                    }
}

保存事件：

局部对象的声明：
