ASP.NET 常用语句代码

1. 打开新的窗口并传送参数:

传送参数:

  response.write( "" )

  接收参数:

  
string a = Request.QueryString( " id " );

  
string b = Request.QueryString( " id1 " );

         2.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;} " )

   3.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()

         4.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;

  }

   }

    5.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( " onclick " , " 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 + " ’) " );

  }

 

  6.表格超连接列传递参数

& name = ’’ />

  7.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=’’; " );

  }

    8.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 " ))


    9.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

  10.清空Cookie

Cookie.Expires = [DateTime];

   Response.Cookies( " UserName " ).Expires = 0

 

  11.自定义异常处理

// 自定义异常处理类
using System;
using System.Diagnostics;

namespace MyAppException
{
 
/// <summary>
 
/// 从系统异常类ApplicationException继承的应用程序异常处理类。
 
/// 自动将异常内容记录到Windows NT / 2000的应用程序日志

  }
 }

}

 

  12.Panel 横向滚动,纵向自动扩展

<asp:panel style = " overflow-x:scroll;overflow-y:auto; " >< / asp:panel>

  13.回车转换成Tab

onkeydown = " if(event.keyCode==13) event.keyCode=9 "

        14.DataGrid超级连接列

DataNavigateUrlField = " 字段名 " DataNavigateUrlFormatString = " http://xx/inc/delete.aspx?ID={0} "

  15.DataGrid行随鼠标变色

private void DGzf_ItemDataBound( object sender, System.Web.UI.WebControls.DataGridItemEventArgs e)

   {

  
if (e.Item.ItemType! = ListItemType.Header)

   {

  e.Item.Attributes.Add( " onmouseout " , " this.style.backgroundColor=\""+e.Item.Style[ " BACKGROUND - COLOR " ]+ " \ "" );

  e.Item.Attributes.Add( " onmouseover " , " this.style.backgroundColor=\""+ " #EFF3F7 " + " \ "" );

  }

  }

         16.模板列

<ASP:TEMPLATECOLUMN visible = " False " sortexpression = " demo " headertext = " ID "
<ITEMTEMPLATE>
<ASP:LABEL text = ’<%# DataBinder.Eval(Container.DataItem, " ArticleID " )%>’ runat = " server " width = " 80% " id = " lblColumn " /
/ ITEMTEMPLATE>
/ ASP:TEMPLATECOLUMN>

<ASP:TEMPLATECOLUMN headertext = " 选中 "
<HEADERSTYLE wrap = " False " horizontalalign = " Center " >< / HEADERSTYLE>
<ITEMTEMPLATE>
<ASP:CHECKBOX id = " chkExport " runat = " server " /
/ ITEMTEMPLATE>
<EDITITEMTEMPLATE>
<ASP:CHECKBOX id = " chkExportON " runat = " server " enabled = " true " /
/ EDITITEMTEMPLATE>
/ ASP:TEMPLATECOLUMN>
   后台代码

protected void CheckAll_CheckedChanged( object sender, System.EventArgs e)
{
 
// 改变列的选定,实现全选或 全不选。
 CheckBox chkExport ;
 
if ( CheckAll.Checked)
  {
  foreach(DataGridItem oDataGridItem in MyDataGrid.Items)
  {
    chkExport = (CheckBox)oDataGridItem.FindControl( " chkExport " );
   chkExport.Checked = true ;
  }
 }
 
else
 {
  foreach(DataGridItem oDataGridItem in MyDataGrid.Items)
   {
   chkExport = (CheckBox)oDataGridItem.FindControl( " chkExport " );
   chkExport.Checked = false ;
  }
 }
}

 

  17.数字格式化

【的结果是500. 0000 ,怎样格式化为500. 00 ?】


  
int i = 123456 ;

  
string s = i.ToString( " ###,###.00 " );

     18.日期格式化

【格式化日期】

  取出来,一般是 object((DateTime)objectFromDB).ToString( " yyyy-MM-dd " );

  【日期的验证表达式】

  A.以下正确的输入格式: [ 2004 - 2 - 29 ], [ 2004 - 02 - 29 10 : 29 : 39 pm], [ 2004 / 12 / 31 ]

  
^ (( \ d{ 2 }(([ 02468 ][ 048 ])|([ 13579 ][ 26 ]))[ \-\/\ s]?(((( 0 ?[ 13578 ])|( 1 [ 02 ]))[ \-\/\ s]?(( 0 ?[ 1 - 9 ])|([ 1 - 2 ][ 0 - 9 ])|( 3 [ 01 ])))|((( 0 ?[ 469 ])|( 11 ))[ \-\/\ s]?(( 0 ?[ 1 - 9 ])|([ 1 - 2 ][ 0 - 9 ])|( 30 )))|( 0 ? 2 [ \-\/\ s]?(( 0 ?[ 1 - 9 ])|([ 1 - 2 ][ 0 - 9 ])))))|( \ d{ 2 }(([ 02468 ][ 1235679 ])|([ 13579 ][ 01345789 ]))[ \-\/\ s]?(((( 0 ?[ 13578 ])|( 1 [ 02 ]))[ \-\/\ s]?(( 0 ?[ 1 - 9 ])|([ 1 - 2 ][ 0 - 9 ])|( 3 [ 01 ])))|((( 0 ?[ 469 ])|( 11 ))[ \-\/\ s]?(( 0 ?[ 1 - 9 ])|([ 1 - 2 ][ 0 - 9 ])|( 30 )))|( 0 ? 2 [ \-\/\ s]?(( 0 ?[ 1 - 9 ])|( 1 [ 0 - 9 ])|( 2 [ 0 - 8 ]))))))( \ s((( 0 ?[ 1 - 9 ])|( 1 [ 0 - 2 ])) \ :([ 0 - 5 ][ 0 - 9 ])(( \ s)|( \ :([ 0 - 5 ][ 0 - 9 ]) \ s))([AM|PM|am|pm]{ 2 , 2 })))?$

  B.以下正确的输入格式:[ 0001 - 12 - 31 ], [ 9999 09 30 ], [ 2002 / 03 / 03 ]

  
^\ d{ 4 }[ \-\/\ s]?(((( 0 [ 13578 ])|( 1 [ 02 ]))[ \-\/\ s]?(([ 0 - 2 ][ 0 - 9 ])|( 3 [ 01 ])))|((( 0 [ 469 ])|( 11 ))[ \-\/\ s]?(([ 0 - 2 ][ 0 - 9 ])|( 30 )))|( 02 [ \-\/\ s]?[ 0 - 2 ][ 0 - 9 ]))$

  【大小写转换】

   HttpUtility.HtmlEncode( string );

  HttpUtility.HtmlDecode( string )

  19.如何设定全局变量

Global.asax中

   Application_Start()事件中

  添加Application[属性名] = xxx;

  就是你的全局变量

    20.怎样作到HyperLinkColumn生成的连接后,点击连接,打开新窗口?

HyperLinkColumn有个属性Target,将器值设置 成 " _blank " 即可.(Target = " _blank " )

   【ASPNETMENU】点击菜单项弹出新窗口

  在你的menuData.xml文件的菜单项中加入URLTarget = " _blank " ,如:

<?xml version = " 1.0 " encoding = " GB2312 " ?>
<MenuData ImagesBaseURL = " images/ "
<MenuGroup>
<MenuItem Label = " 内参信息 " URL = " Infomation.aspx "
<MenuGroup ID = " BBC "
<MenuItem Label = " 公告信息 " URL = " Infomation.aspx " URLTarget = " _blank " LeftIcon = " file.gif " /
<MenuItem Label = " 编制信息简报 " URL = " NewInfo.aspx " LeftIcon = " file.gif " /
......
  最好将你的aspnetmenu升级到1.2版

 

  21.读取DataGrid控件TextBox值

foreach(DataGrid dgi in yourDataGrid.Items)
{
 TextBox tb = (TextBox)dgi.FindControl( " yourTextBoxId " );
  tb.Text....

    23.在DataGrid中有3个模板列包含Textbox分别为 DG_ShuLiang (数量) DG_DanJian(单价) DG_JinE(金额)分别在5.6.7列,要求在录入数量及单价的时候自动算出金额即:数量*单价=金额还要求录入时限制为 数值型.我如何用客户端脚本实现这个功能?

〖思归〗

<asp:TemplateColumn HeaderText = " 数量 "
<ItemTemplate>
<asp:TextBox id = " ShuLiang " runat = ’server’ Text = ’<%# DataBinder.Eval(Container.DataItem, " DG_ShuLiang " )%>’
onkeyup = " javascript:DoCal() "
/

<asp:RegularExpressionValidator id = " revS " runat = " server " ControlToValidate = " ShuLiang " ErrorMessage = " must be integer " ValidationExpression = " ^\d+$ " /
/ ItemTemplate>
/ asp:TemplateColumn>

<asp:TemplateColumn HeaderText = " 单价 "
<ItemTemplate>
<asp:TextBox id = " DanJian " runat = ’server’ Text = ’<%# DataBinder.Eval(Container.DataItem, " DG_DanJian " )%>’
onkeyup = " javascript:DoCal() "
/

<asp:RegularExpressionValidator id = " revS2 " runat = " server " ControlToValidate = " DanJian " ErrorMessage = " must be numeric " ValidationExpression = " ^\d+(\.\d*)?$ " /

/ ItemTemplate>
/ asp:TemplateColumn>

<asp:TemplateColumn HeaderText = " 金额 "
<ItemTemplate>
<asp:TextBox id = " JinE " runat = ’server’ Text = ’<%# DataBinder.Eval(Container.DataItem, " DG_JinE " )%>’ /
/ ItemTemplate>
/ asp:TemplateColumn> <script language = " javascript "
function DoCal()
{
  var e = event.srcElement;
 var row = e.parentNode.parentNode;
 var txts = row.all.tags( " INPUT " );
 
if (!txts.length || txts.length < 3 )
  return;

 var q = txts[txts.length - 3 ].value;
 var p = txts[txts.length - 2 ].value;

 
if (isNaN(q) || isNaN(p))
  return;

 q = parseInt(q);
 p = parseFloat(p);

 txts[txts.length - 1 ].value = (q * p).toFixed( 2 );
}
/ script>



 

  24.datagrid选定比较底下的行时,为什么总是刷新一下,然后就滚动到了最上面,刚才选定的行因屏幕的关系就看不到了。

page_load

   page.smartNavigation = true

   25.在Datagrid中修改数据,当点击编辑键时,数据出现在文本框中,怎么控制文本框的大小 ?

private void DataGrid1_ItemDataBound(obj sender,DataGridItemEventArgs e)
{
 
for ( int i = 0 ;i<e.Item.Cells.Count - 1 ;i ++ )
  
if (e.Item.ItemType == ListItemType.EditType)
  {
   e.Item.Cells[i].Attributes.Add( " Width " , " 80px " )
  }
}

        26.对话框

private static string ScriptBegin = "" ;

  
public static void ConfirmMessageBox( string PageTarget, string Content)

  {

  
string ConfirmContent = " var retValue=window.confirm(’ " + Content + " ’); " + " if(retValue){window.location=’ " + PageTarget + " ’;} " ;

  ConfirmContent = ScriptBegin + ConfirmContent + ScriptEnd;

  Page ParameterPage = (Page)System.Web.HttpContext.Current.Handler;

   ParameterPage.RegisterStartupScript( " confirm " ,ConfirmContent);

  
// Response.Write(strScript);

   }

        27.  

1.1 取当前年月日时分秒

currentTime = System.DateTime.Now;
   
1.2 取当前年

int = DateTime.Now.Year;
  
1.3 取当前月

int = DateTime.Now.Month;
  
1.4 取当前日

int = DateTime.Now.Day;
  
1.5 取当前时

int = DateTime.Now.Hour;
  
1.6 取当前分

int = DateTime.Now.Minute;
  
1.7 取当前秒

int = DateTime.Now.Second;
  
1.8 取当前毫秒

int 毫秒 = DateTime.Now.Millisecond;

   28.自定义分页代码:

先定义变量 :

public static int pageCount; // 总页面数
public static int curPageIndex = 1 ; // 当前页面
  下一页:

if (DataGrid1.CurrentPageIndex < (DataGrid1.PageCount - 1 ))
{
 DataGrid1.CurrentPageIndex += 1 ;
 curPageIndex += 1 ;
}

bind(); // DataGrid1数据绑定函数
  上一页:

if (DataGrid1.CurrentPageIndex > 0 )
{
  DataGrid1.CurrentPageIndex += 1 ;
 curPageIndex -= 1 ;
}

bind(); // DataGrid1数据绑定函数
  直接页面跳转:

int a = int .Parse(JumpPage.Value.Trim()); // JumpPage.Value.Trim()为跳 转值

if (a<DataGrid1.PageCount)
{
  this.DataGrid1.CurrentPageIndex = a;
}

bind();



 

  29.DataGrid使用:

添加删除确认:

private void DataGrid1_ItemCreated( object sender, System.Web.UI.WebControls.DataGridItemEventArgs e)
{
  foreach(DataGridItem di in this.DataGrid1.Items)
 {
  
if (di.ItemType == ListItemType.Item||di.ItemType == ListItemType.AlternatingItem)
  {
   ((LinkButton)di.Cells[ 8 ].Controls[ 0 ]).Attributes.Add( " onclick " , " return confirm(’确认删除此项吗?’); " );
  }
 }
}
  样式交替:

ListItemType itemType = e.Item.ItemType;

if (itemType == ListItemType.Item )
{
  e.Item.Attributes[ " onmouseout " ] = " javascript:this.style.backgroundColor=’#FFFFFF’; " ;
 e.Item.Attributes[ " onmouseover " ] = " javascript:this.style.backgroundColor=’#d9ece1’;cursor=’hand’; " ;
}
else if ( itemType == ListItemType.AlternatingItem)
{
 e.Item.Attributes[ " onmouseout " ] = " javascript:this.style.backgroundColor=’#a0d7c4’; " ;
 e.Item.Attributes[ " onmouseover " ] = " javascript:this.style.backgroundColor=’#d9ece1’;cursor=’hand’; " ;
}
  添加一个编号列:

DataTable dt = c.ExecuteRtnTableForAccess(sqltxt); // 执行sql返回的DataTable
DataColumn dc = dt.Columns.Add( " number " ,System.Type.GetType( " System.String " ));

for ( int i = 0 ;i<dt.Rows.Count;i ++ )
{
 dt.Rows[i][ " number " ] = (i + 1 ).ToString();
}

DataGrid1.DataSource = dt;
DataGrid1.DataBind();
  DataGrid1中添加一个CheckBox,页面中添加一个全选框

private void CheckBox2_CheckedChanged( object sender, System.EventArgs e)
{
 foreach(DataGridItem thisitem in DataGrid1.Items)
 {
  ((CheckBox)thisitem.Cells[ 0 ].Controls[ 1 ]).Checked = CheckBox2.Checked;
 }
}
  将当前页面中DataGrid1显示的数据全部删除

foreach(DataGridItem thisitem in DataGrid1.Items)
{
 
if (((CheckBox)thisitem.Cells[ 0 ].Controls[ 1 ]).Checked)
 {
  
string strloginid = DataGrid1.DataKeys[thisitem.ItemIndex].ToString();
  Del (strloginid); // 删除函数
 }
}

 

  30.当文件在不同目录下,需要获取数据库连接字符串(如果连接字符串放在Web.config,然后在Global.asax中初始化)

  在Application_Start中添加以下代码:

Application[ " ConnStr " ] = this.Context.Request.PhysicalApplicationPath + ConfigurationSettings.

   AppSettings[ " ConnStr " ].ToString();

 

    31. 变量.ToString()

字符型转换 转为字符串

  
12345 .ToString( " n " ); // 生 成 12 , 345.00

  
12345 .ToString( " C " ); // 生 成 ¥ 12 , 345.00

  
12345 .ToString( " e " ); // 生 成 1.234500e+004

  
12345 .ToString( " f4 " ); // 生成 12345.0000

  
12345 .ToString( " x " ); // 生成 3039 (16进制)

  
12345 .ToString( " p " ); // 生 成 1 , 234 , 500.00 %

    32、变量.Substring(参数1,参数2);

  截取字串的一部分,参数1为左起始位数,参数2为截取几位。 如:string s1 = str.Substring(0,2);

  33.在自己的网站上登陆其他网站:(如果你的页面是通过嵌套方式的话,因为一个页面只能有一个FORM,这时可以导向另外一个页面再提交登陆 信息)

<SCRIPT language = " javascript "
<! --
 
function gook(pws)
  {
  frm.submit();
 }
//--

/ SCRIPT> <body leftMargin = " 0 " topMargin = " 0 " onload = " javascript:gook() " marginwidth = " 0 " marginheight = " 0 "
<form name = " frm " action = " http://220.194.55.68:6080/login.php?retid=7259 " method = " post "
<tr>
<td>
<input id = " f_user " type = " hidden " size = " 1 " name = " f_user " runat = " server "
<input id = " f_domain " type = " hidden " size = " 1 " name = " f_domain " runat = " server "
<input class = " box " id = " f_pass " type = " hidden " size = " 1 " name = " pwshow " runat = " server "

<INPUT id = " lng " type = " hidden " maxLength = " 20 " size = " 1 " value = " 5 " name = " lng "
<INPUT id = " tem " type = " hidden " size = " 1 " value = " 2 " name = " tem "

/ td>

/ tr>

/ form>
  文本 框的名称必须是你要登陆的网页上的名称,如果源码不行可以用vsniffer 看看。

  下面是获取用户输入的登陆信息的代码:

string name;
name = Request.QueryString[ " EmailName " ];

try
{
 
int a = name.IndexOf( " @ " , 0 ,name.Length);
 f_user.Value = name.Substring( 0 ,a);
 f_domain.Value = name.Substring(a + 1 ,name.Length - (a + 1 ));
 f_pass.Value = Request.QueryString[ " Psw " ];
}

catch
{
  Script.Alert( " 错误的邮箱! " );
  Server.Transfer( " index.aspx " );
