.net 自用代码大全天天收藏(C#版)_01

PMTM01:
RowCommand事件:
if (e.CommandName == "imgbtn")
{
ImageButton img = (ImageButton)(e.CommandSource);
string sTemp = ((Label)(img.FindControl("lblID"))).Text;
...
}
增加一个Session
Session.Add("PM01Q", this.ViewState["01"]);
//偉递修改ＩＤ
string sTemp = ((Label)(img.FindControl("lblID"))).Text;
Response.Redirect("PMTM01M.aspx?s_PROGR_CODE_01Q=" + sTemp + "", true);
//得到上一個頁面偉過來的修改ＩＤ
if (Request.QueryString["s_PROGR_CODE_01Q"] != null)
{
s_PROGR_CODE = Request.QueryString["s_PROGR_CODE_01Q"].ToString().Trim();//得到上一個頁面偉過來的修改ＩＤ
}

使用AlertMessage1控件:
this.AlertMessage1.AddOkMsg(Resources.WebResource.X012);//修改成功

后台注册控件的onblur事件:
txtSDPLAN_HOUR.Attributes.Add("onblur", "if(ctl00_cphPage_txtSDPLAN_HOUR.value==''){}else if(!isNumeric(ctl00_cphPage_txtSDPLAN_HOUR.value )){ AddMsg(getMsg('J00023'));}");

//添加一個全部的選項 在第一项位置:
drpPROGR_KIND.Items.Insert(0, new ListItem("", "0"));
//設置選中項，下標從0開始
drpPROGR_KIND.Items[i_ItemIndex].Selected = true;

***一种不错的写法:
通过GetModel()返回一个已经装载好的对象.
private Boolean isUpdate()
{
com.thoughtchina.pms.BLL.PM045TB o_PM045TB = new com.thoughtchina.pms.BLL.PM045TB();
com.thoughtchina.pms.Model.PM045TB o_Model = GetModel();
try
{
o_PM045TB.Update(o_Model);
return true;
}
catch
{
return false;
}
}

转换日期格式:
Convert.ToDateTime(o_DA.Rows[0]["SDEXEC_END"].ToString()).ToString("yyyy/MM/dd")

给GRV中的控件注册JS事件:
if (this.PMSGRID1.Rows.Count != 0)
{
((CheckBox)(PMSGRID1.HeaderRow.Cells[0].Controls[1])).Attributes.Add("onclick", "fun_SelectAllCheck(this);");
}

Equals的前后比较内容:
!"".Equals(s_ItemName)

Context:
o_Model = (com.thoughtchina.pms.Model.PM045TB)this.Context.Items["04"];
this.Context.Items.Add("04",(com.thoughtchina.pms.Model.PM045TB)o_Model45);

txtBIRTHDAY.Value = o_PM.SDPLAN_START == new DateTime() ? "" : o_PM.SDPLAN_START.ToString("yyyy/MM/dd");

PMTM01的循环删除:
or (int i = 0; i < PMSGRID1.Rows.Count; i++)
{
GridViewRow row = PMSGRID1.Rows[i];
bool isChecked = ((CheckBox)row.FindControl("chkSelect")).Checked;
if (isChecked)
{
string strSelect = ((Label)row.FindControl("lblID")).Text.ToString().Trim();
//組合SQL語句//執行
o_PM045TB.Delete(ms_ProjectCode, strSelect);
}
}

使用StringWriter 输出Excel:(数据为字符串并接)
StringWriter o_SW = new StringWriter();
string s_Str = string.Empty;
s_Str = "QMS版本：060330 ";
o_SW.WriteLine(s_Str);
o_SW.Close();
Response.Clear();
Response.ClearHeaders();
Response.AddHeader("Content-Disposition", "attachment; filename=PMTM01.xls");
Response.ContentType = "application/ms-excel";
Response.ContentEncoding = System.Text.Encoding.GetEncoding("BIG5");
Response.Write(o_SW);
Response.End();

服务器下拉框的绑定与运用代码:
drpPROGR_KIND.Items.Clear();//清空下拉框的內容
drpPROGR_KIND.DataSource = o_DS.Tables[0];//綁定結果集
drpPROGR_KIND.DataTextField = "ENTRY_VALUE";//顯示的字段
drpPROGR_KIND.DataValueField = "ENTRY_KEY";//綁定VALUE值
drpPROGR_KIND.DataBind();
drpPROGR_KIND.Items.Insert(0, new ListItem("", "0"));//添加一個全部的選項
drpPROGR_KIND.Items[i_ItemIndex].Selected = true;//設置第一項為選中項，下標從0開始

RowDataBound事件:
if (e.Row.RowIndex > -1)
{
if (e.Row.Cells[30].Text.Length > 8)
{
e.Row.Cells[30].Attributes.Add("title", e.Row.Cells[30].Text);
e.Row.Cells[30].Text = e.Row.Cells[30].Text.Substring(0, 8).ToString() + "...";
}
}
表头:
if (e.Row.RowIndex == 0)
{
((CheckBox)(PMSGRID1.HeaderRow.Cells[0].Controls[1])).Attributes.Add("onclick", "fun_SelectAllCheck(this);");
}
