决定一个人富有的三个条件,一是出身,二是运气,三是努力
If you can dream it,you can do it! Nothing Impossible~

1.//弹出对话框.点击转向指定页面
Response.Write(<script>window.alert('该会员没有提交申请,请重新提交!') </script>);
Response.Write(<script>window.location='http://www.51aspx.com/bizpulic/upmeb.aspx' </script>);

2.//弹出对话框
Response.Write(<script language='javascript'>alert('产品添加成功!') </script >);


3.//删除文件
string filename =20059595157517.jpg;
pub.util.DeleteFile(HttpContext.Current.Server.MapPath(../file/) +filename);

4.//绑定下拉列表框datalist
System.Data.DataView dv=conn.Exec_ex(select -1 as code,'请选择经营模式'
as content from dealin union select code,content from dealin;);
this.dealincode.DataSource=dv;
this.dealincode.DataTextField=content;
this.dealincode.DataValueField=code;   
this.dealincode.DataBind();
this.dealincode.Items.FindByValue(dv[0][dealincode].ToString()).Selected=true;

5.//时间去秒显示
<%# System.DateTime.Parse(DataBinder.Eval (Container.DataItem,begtime).ToString()).ToShortDateString()%>

6.//标题带链接
<%# <a class=\12c\ target=\_blank\href=\http://www.51aspx/CV/_DataBinder.Eval
(Container.DataItem,procode)+.html \>
DataBinder.Eval(Container.DataItem,proname&quot;) </a>%>

7.//修改转向
<%# <A href=\&quot;editpushpro.aspx?id=+DataBinder.Eval
(Container.DataItem,code)>修改 
</A>%>

8.//弹出确定按钮
<%# &quot; <A id=\btnDelete\ onclick=\return confirm('你是否
确定删除这条记录吗?');\ href=\pushproduct.aspx?
dl=DataBinder.Eval(Container.DataItem,code)
>删除</A>%>

9.//输出数据格式化 "{0:F2}" 是格式 F2表示小数点后剩两位
<%# DataBinder.Eval(Container, DataItem.PriceMoney,{0:F2} ) %>

10.//提取动态网页内容
Uri uri = new Uri(http://www.51aspx.com/);
  WebRequest req = WebRequest.Create(uri);
  WebResponse resp = req.GetResponse();
  Stream str = resp.GetResponseStream();
  StreamReader sr = new StreamReader(str,System.Text.Encoding.Default);
  string t = sr.ReadToEnd();
  this.Response.Write(t.ToString());

11.//获取" . "后面的字符
i.ToString().Trim().Substring(i.ToString().Trim().LastIndexOf(.) +1).ToLower().Trim()


12. 打开新的窗口并传送参数:
  传送参数:
response.write(<script>window.open(’*.aspx?
id=+this.DropDownList1.SelectIndex+ id1=+...+’)<
/script>)

接收参数:
string a = Request.QueryString(id);
string b = Request.QueryString(id1);


12.为按钮添加对话框
Button1.Attributes.Add(onclick,return confirm(’确认?’) );
button.attributes.add(onclick,if(confirm(’are you sure...? ’)){return true;}else{return false;})

13.删除表格选定记录
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex];
string deleteCmd = ”Delete from Employee where emp_id =  + intEmpID.ToString() +“

14.删除表格记录警告
private void DataGrid_ItemCreated(Object sender,DataGridItemEventArgs e)
{
  switch(e.Item.ItemType)
  {
  case ListItemType.Item :
  case ListItemType.AlternatingItem :
  case ListItemType.EditItem:
  TableCell myTableCell;
  myTableCell = e.Item.Cells[14];
  LinkButton myDeleteButton ;
  myDeleteButton = (LinkButton)myTableCell.Controls[0];
  myDeleteButton.Attributes.Add(onclick,return confirm(’您是否确定要删除这条信息’););
  break;
  default:
  break;
  }
}

15.点击表格行链接另一页
private void grdCustomer_ItemDataBound(object sender,
System.Web.UI.WebControls.DataGridItemEventArgs e)
{
  //点击表格打开
  if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem)
  e.Item.Attributes.Add(&quot;onclick&quot;,&quot;window.open(’Default.aspx?id=+ e.Item.Cells[0].Text + ’););
}


双击表格连接到另一页
  在itemDataBind事件中
if(e.Item.ItemType == ListItemType.Item || e.Item.ItemType ==
ListItemType.AlternatingItem)
{
  string orderItemID =e.item.cells[1].Text;
  e.item.Attributes.Add(ondblclick, location.href=’../ShippedGrid.aspx?id= + orderItemID + ‘);
}

双击表格打开新一页
if(e.Item.ItemType == ListItemType.Item || e.Item.ItemType ==
ListItemType.AlternatingItem)
{
  string orderItemID =e.item.cells[1].Text;
  e.item.Attributes.Add(ondblclick, open (’../ShippedGrid.aspx?id=+ orderItemID + ’));
}

16.表格超连接列传递参数
<asp:HyperLinkColumn Target=_blank headertext=ID号 DataTextField=id NavigateUrl=aaa.aspx?id=’
  <%# DataBinder.Eval(Container.DataItem, 数据字段1)%>’ &amp;
name=’<%# DataBinder.Eval(Container.DataItem, 数据字段2)%>’ / >


17.表格点击改变颜色
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem)
{
  e.Item.Attributes.Add (onclick,this.style.backgroundColor=’#99cc00’;
    this.style.color=’buttontext’;this.style.cursor=’default’;);
}

写在DataGrid的_ItemDataBound里
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem)
{
e.Item.Attributes.Add(onmouseover,this.style.backgroundColor=’#99cc00’;
  this.style.color=’buttontext’;this.style.cursor=’default’;);
e.Item.Attributes.Add(onmouseout,this.style.backgroundColor= ’’;this.style.color=’’;);
}

18.关于日期格式
  日期格式设定
DataFormatString="{0:yyyy-MM-dd}"
  我觉得应该在itembound事件中
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd"))


19.获取错误信息并到指定页面
不要使用Response.Redirect,而应该使用Server.Transfer

e.g


// in global.asax
protected void Application_Error(Object sender, EventArgs e)


     if (Server.GetLastError() is HttpUnhandledException) 
     Server.Transfer(MyErrorPage.aspx); 
     //其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :)
}
Redirect会导致post-back的产生从而丢失了错误信息,所以页面导向应该直接在服
务器端执行,这样就可以在错误处理页面得到出错信息并进行相应的处理


20.清空Cookie
Cookie.Expires=[DateTime];
Response.Cookies(UserName&quot;).Expires = 0
