1. 打开新的窗口并传送参数:
传送参数:
\n
response.write(“<script>window.open(’*.aspx?id=”+this.DropDownList1.SelectIndex+”&id1=”+…+”’)</script>”)
\n
接收参数:
\n
string a = Request.QueryString(“id”);
string b = Request.QueryString(“id1″);
\n
2.为按钮添加对话框
\n
Button1.Attributes.Add(“onclick“,”return confirm(’确认?’)”);
button.attributes.add(“onclick“,”if(confirm(’are you sure…?’)){return true;}else{return false;}”)
\n
3.删除表格选定记录
\n
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex];
string deleteCmd = “DELETE from Employee where emp_id = ” + intEmpID.ToString()
\n
4.删除表格记录警告
\n
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;
}
\n
}
\n
5.点击表格行链接另一页
\n
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 + “’);”);
}
\n
双击表格连接到另一页
\n
在itemDataBind事件中
\n
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 + “’”);
}
\n
双击表格打开新一页
\n
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 + “’)”);
}
\n
★特别注意:【?id=】 处不能为 【?id =】
\n
6.表格超连接列传递参数
\n
<asp:HyperLinkColumn Target=”_blank” headertext=”ID号” DataTextField=”id” NavigateUrl=”aaa.aspx?id=’
<%# DataBinder.Eval(Container.DataItem, “数据字段1″)%>’ & name=’<%# DataBinder.Eval(Container.DataItem, “数据字段2″)%>’ />
\n
7.表格点击改变颜色
\n
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’;”);
}
\n
写在DataGrid的_ItemDataBound里
\n
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=’’;”);
}
\n
8.关于日期格式
\n
日期格式设定
\n
DataFormatString=”{0:yyyy-MM-dd}”
\n
我觉得应该在itembound事件中
\n
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString(“yyyy-MM-dd”))
\n
9.获取错误信息并到指定页面
\n
不要使用Response.Redirect,而应该使用Server.Transfer
\n
e.g
\n
// in global.asax
protected void Application_Error(Object sender, EventArgs e) {
if (Server.GetLastError() is HttpUnhandledException)
Server.Transfer(“MyErrorPage.aspx”);
\n
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了
}
\n
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
\n
10.清空Cookie
\n
Cookie.Expires=[DateTime];
Response.Cookies(“UserName”).Expires = 0
11.自定义异常处理
\n
//自定义异常处理类
using System;
using System.Diagnostics;
\n
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
/// </summary>
public class AppException:System.ApplicationException
{
public AppException()
{
if (ApplicationConfiguration.EventLogEnabled)LogEvent(“出现一个未知错误。”);
}
\n
public AppException(string message)
{
LogEvent(message);
}
\n
public AppException(string message,Exception innerException)
{
LogEvent(message);
if (innerException != null)
{
LogEvent(innerException.Message);
}
}
\n
//日志记录类
using System;
using System.Configuration;
using System.Diagnostics;
using System.IO;
using System.Text;
using System.Threading;
\n
namespace MyEventLog
{
/// <summary>

public static String FormatException(Exception ex, String catchInfo)
{

if (catchInfo != String.Empty)
{
strBuilder.Append(catchInfo).Append(“\\r\\n”);
}
strBuilder.Append(ex.Message).Append(“\\r\\n”).Append(ex.StackTrace);
return strBuilder.ToString();
}
\n
/// <summary>
/// 实际事件日志写入方法
/// <param name=”level”>要记录信息的级别(error,warning,info,trace).</param>
/// <param name=”messageText”>要记录的文本.</param>
/// </summary>
private static void WriteLog(TraceLevel level, String messageText)
{
try
{
EventLogEntryType LogEntryType;
switch (level)
{
case TraceLevel.Error:
LogEntryType = EventLogEntryType.Error;
break;
case TraceLevel.Warning:
LogEntryType = EventLogEntryType.Warning;
break;
case TraceLevel.Inf
LogEntryType = EventLogEntryType.Information;
break;
case TraceLevel.Verbose:
LogEntryType = EventLogEntryType.SuccessAudit;
break;
default:
LogEntryType = EventLogEntryType.SuccessAudit;
break;
}
\n
EventLog eventLog = new EventLog(“Application”, ApplicationConfiguration.EventLogMachineName, ApplicationConfiguration.EventLogSourceName );
//写入事件日志
eventLog.WriteEntry(messageText, LogEntryType);
\n
}
catch {} //忽略任何异常
}
} //class ApplicationLog
}
\n
12.Panel 横向滚动,纵向自动扩展
\n
<asp:panel style=”overflow-x:scroll;overflow-y:auto;”></asp:panel>
\n
13.回车转换成Tab
\n
<script language=”javascript” for=”document” event=”onkeydown”>
if(event.keyCode==13 && event.srcElement.type!=’button’ && event.srcElement.type!=’submit’ && event.srcElement.type!=’reset’ && event.srcElement.type!=’’&& event.srcElement.type!=’textarea’);
event.keyCode=9;
</script>
\n
onkeydown=”if(event.keyCode==13) event.keyCode=9″
\n
14.DataGrid超级连接列
\n
DataNavigateUrlField=”字段名” DataNavigateUrlFormatString=”http://xx/inc/delete.aspx?ID={0}”
\n
15.DataGrid行随鼠标变色
\n
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″+”\\”");
}
}

\n
后台代码
\n
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;
}
}
}
\n
17.数字格式化
\n
【<%#Container.DataItem(“price”)%>的结果是500.0000,怎样格式化为500.00?】
\n
<%#Container.DataItem(“price”,”{0:¥#,##0.00}”)%>
\n
int i=123456;
string s=i.ToString(“###,###.00″);
\n
18.日期格式化
\n
【aspx页面内:<%# DataBinder.Eval(Container.DataItem,”Company_Ureg_Date”)%>
\n
显示为: 2004-8-11 19:44:28
\n
我只想要:2004-8-11 】
\n
<%# DataBinder.Eval(Container.DataItem,”Company_Ureg_Date”,”{0:yyyy-M-d}”)%>
\n
应该如何改?
\n
【格式化日期】
\n
取出来,一般是object((DateTime)objectFromDB).ToString(“yyyy-MM-dd”);
\n
【日期的验证表达式】
\n
A.以下正确的输入格式: [2004-2-29], [2004-02-29 10:29:39 pm], [2004/12/31]
\n
^((\\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})))?
\n
B.以下正确的输入格式:[0001-12-31], [9999 09 30], [2002/03/03]
\n
^\\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]))
\n
【大小写转换】
\n
HttpUtility.HtmlEncode(string);
HttpUtility.HtmlDecode(string)
\n
19.如何设定全局变量
\n
Global.asax中
\n
Application_Start()事件中
\n
添加Application[属性名] = xxx;
\n
就是你的全局变量
\n
20.怎样作到HyperLinkColumn生成的连接后,点击连接,打开新窗口?
\n
HyperLinkColumn有个属性Target,将器值设置成”_blank”即可.(Target=”_blank”)
\n
【ASPNETMENU】点击菜单项弹出新窗口
\n
在你的menuData.xml文件的菜单项中加入URLTarget=”_blank”,如:
\n
<?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” />
……
\n
最好将你的aspnetmenu升级到1.2版
\n
21.读取DataGrid控件TextBox值
\n
foreach(DataGrid dgi in yourDataGrid.Items)
{
TextBox tb = (TextBox)dgi.FindControl(“yourTextBoxId”);
tb.Text….
}
\n
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?
\n
〖思归〗
\n
<asp:TemplateColumn HeaderText=”数量”>
<ItemTemplate>
<asp:TextBox id=”ShuLiang” runat=’server’ Text=’<%# DataBinder.Eval(Container.DataItem,”DG_ShuLiang”)%>’
onkeyup=”javascript:DoCal()”
/>
\n
<asp:RegularExpressionValidator id=”revS” runat=”server” ControlToValidate=”ShuLiang” ErrorMessage=”must be integer” ValidationExpression=”^\\d+” />
</ItemTemplate>
</asp:TemplateColumn>
\n
<asp:TemplateColumn HeaderText=”单价”>
<ItemTemplate>
<asp:TextBox id=”DanJian” runat=’server’ Text=’<%# DataBinder.Eval(Container.DataItem,”DG_DanJian”)%>’
onkeyup=”javascript:DoCal()”
/>
\n
<asp:RegularExpressionValidator id=”revS2″ runat=”server” ControlToValidate=”DanJian” ErrorMessage=”must be numeric” ValidationExpression=”^\\d+(\\.\\d*)?” />
\n
</ItemTemplate>
</asp:TemplateColumn>
\n
<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;
\n
var q = txts[txts.length-3].value;
var p = txts[txts.length-2].value;
\n
if (isNaN(q) || isNaN(p))
return;
\n
q = parseInt(q);
p = parseFloat(p);
\n
txts[txts.length-1].value = (q * p).toFixed(2);
}
</script>
\n
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。
\n
page_load
page.smartNavigation=true
\n
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 ?
\n
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”)
}
}
\n
26.对话框
\n
private static string ScriptBegin = “<script language=\\”JavaScript\\”>”;
private static string ScriptEnd = “</script>”;
\n
public static void ConfirmMessageBox(string PageTarget,string Content)
{
string ConfirmContent=”var retValue=window.confirm(’”+Content+”’);”+”if(retValue){window.location=’”+PageTarget+”’;}”;
\n
ConfirmContent=ScriptBegin + ConfirmContent + ScriptEnd;
\n
Page ParameterPage = (Page)System.Web.HttpContext.Current.Handler;
ParameterPage.RegisterStartupScript(“confirm”,ConfirmContent);
//Response.Write(strScript);
}
\n
27. 将时间格式化:string aa=DateTime.Now.ToString(“yyyy年MM月dd日”);
\n
1.1 取当前年月日时分秒
\n
currentTime=System.DateTime.Now;
\n
1.2 取当前年
\n
int 年= DateTime.Now.Year;
\n
1.3 取当前月
\n
int 月= DateTime.Now.Month;
\n
1.4 取当前日
\n
int 日= DateTime.Now.Day;
\n
1.5 取当前时
\n
int 时= DateTime.Now.Hour;
\n
1.6 取当前分
\n
int 分= DateTime.Now.Minute;
\n
1.7 取当前秒
\n
int 秒= DateTime.Now.Second;
\n
1.8 取当前毫秒
\n
int 毫秒= DateTime.Now.Millisecond;
28.自定义分页代码:
\n
先定义变量 :
\n
public static int pageCount; //总页面数
public static int curPageIndex=1; //当前页面
\n
下一页:
\n
if(DataGrid1.CurrentPageIndex < (DataGrid1.PageCount – 1))
{
DataGrid1.CurrentPageIndex += 1;
curPageIndex+=1;
}
\n
bind(); // DataGrid1数据绑定函数
\n
上一页:
\n
if(DataGrid1.CurrentPageIndex >0)
{
DataGrid1.CurrentPageIndex += 1;
curPageIndex-=1;
}
\n
bind(); // DataGrid1数据绑定函数
\n
直接页面跳转:
\n
int a=int.Parse(JumpPage.Value.Trim());//JumpPage.Value.Trim()为跳转值
\n
if(a<DataGrid1.PageCount)
{
this.DataGrid1.CurrentPageIndex=a;
}
\n
bind();
\n
29.DataGrid使用:
\n
添加删除确认:
\n
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?’);”);
}
}
}
\n
样式交替:
\n
ListItemType itemType = e.Item.ItemType;
\n
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’;” ;
}
\n
添加一个编号列:
\n
DataTable dt= c.ExecuteRtnTableForAccess(sqltxt); //执行sql返回的DataTable
DataColumn dc=dt.Columns.Add(“number”,System.Type.GetType(“System.String”));
\n
for(int i=0;i<dt.Rows.Count;i++)
{
dt.Rows[i]["number"]=(i+1).ToString();
}
\n
DataGrid1.DataSource=dt;
DataGrid1.DataBind();
\n
DataGrid1中添加一个CheckBox,页面中添加一个全选框
\n
private void CheckBox2_CheckedChanged(object sender, System.EventArgs e)
{
foreach(DataGridItem thisitem in DataGrid1.Items)
{
((CheckBox)thisitem.Cells[0].Controls[1]).Checked=CheckBox2.Checked;
}
}
\n
将当前页面中DataGrid1显示的数据全部删除
\n
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
}
}
\n
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)
\n
在Application_Start中添加以下代码:
\n
Application["ConnStr"]=this.Context.Request.PhysicalApplicationPath+ConfigurationSettings.
AppSettings["ConnStr"].ToString();
\n
31. 变量.ToString()
\n
字符型转换 转为字符串
\n
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%
\n
32、变量.Substring(参数1,参数2);
\n
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);
\n
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)
\n
<SCRIPT language=”javascript”>
<!–
function gook(pws)
{
frm.submit();
}
//–>
\n
</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”>
\n
<INPUT id=”lng” type=”hidden” maxLength=”20″ size=”1″ value=”5″ name=”lng”>
<INPUT id=”tem” type=”hidden” size=”1″ value=”2″ name=”tem”>
\n
</td>
\n
</tr>
\n
</form>
\n
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。
\n
下面是获取用户输入的登陆信息的代码:
\n
string name;
name=Request.QueryString["EmailName"];
\n
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"];
}
\n
catch
{
Script.Alert(“错误的邮箱!”);
Server.Transfer(“index.aspx”);
}
\n
