【传递数据】
这种方法是使用浏览器的网址来传递数据的,调用网页(WebForm1.aspx)的程序可以这样写:
Dim pram As String
pram = "Var1=" & Server.UrlEncode(TextBox1.Text) & "&"
pram = pram & "Var2=" & Server.UrlEncode(TextBox2.Text)
Response.Redirect("WebForm2.aspx?" & pram)
这里,Textbox1和Textbox2为需要传递的数据,需要注意的是,网页的网址后面要加上”?”,而各个数据之间要加上不含空格的“&”。
而被打开并且接受数据的网页(WebForm2.aspx)可以这样写:
TextBox1.Text = Request.QueryString("var2")
TextBox2.Text = Request.QueryString("var1")
【不同页面传递数据】
Response.Write("<script language=javascript>window.open('Default2.aspx?编号=" + 编号 + "','','channelmode = no,toolbar=no,location=no,directories=no,status=no,menubar=no,scrollbars=no,resizable=no');</script>")

Window.open的参数
window.open('xxxx.asp','Derek','height=100,width=100,status=yes,toolbar=yes,
menubar=no,location=no')
此语句打开一个新窗口,页面为xxxx.asp,名字为Derek,高为100,宽为100,显示状态栏和工具条,不显示菜单和地址。
具体各个属性参数如下:
window.open(URL,name,features)
URL:新窗口的URL地址
name:新窗口的名称,可以为空
featurse:属性控制字符串,在此控制窗口的各种属性,属性之间以逗号隔开。
fullscreen=yes/no 是否全屏,默认no
channelmode=yes/no 是否显示频道栏,默认no
toolbar=yes/no 是否显示工具条,默认no
location=yes/no 是否显示地址栏,默认no
directories=yes/no 是否显示转向按钮,默认no
status=yes/no 是否显示窗口状态条,默认no
menubar=yes/no 是否显示菜单,默认no

【在刷新和提交页面后,保存你的页面滚动条的位置】
Private Sub RetainScrollPosition()
Dim saveScrollPosition As New StringBuilder
Dim setScrollPosition As New StringBuilder
RegisterHiddenField("__SCROLLPOS", "0")
saveScrollPosition.Append("<script language='javascript'>")
saveScrollPosition.Append("function saveScrollPosition() {")
saveScrollPosition.Append(" document.forms[0].__SCROLLPOS.value = thebody.scrollTop;")
saveScrollPosition.Append("}")
saveScrollPosition.Append("thebody.onscroll=saveScrollPosition;")
saveScrollPosition.Append("</script>")
RegisterStartupScript("saveScroll", saveScrollPosition.ToString())
If (Page.IsPostBack = True) Then
setScrollPosition.Append("<script language='javascript'>")
setScrollPosition.Append("function setScrollPosition() {")
setScrollPosition.Append(" thebody.scrollTop = " & Request("__SCROLLPOS") & ";")
setScrollPosition.Append("}")
setScrollPosition.Append("thebody.onload=setScrollPosition;")
setScrollPosition.Append("</script>")
RegisterStartupScript("setScroll", setScrollPosition.ToString())
End If
End Sub
. 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");
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
<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")%>’ />
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CookieCookie.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;

18.日期格式化
【aspx页面内:<%# DataBinder.Eval(Container.DataItem,"Company_Ureg_Date")%>
显示为: 2004-8-11 19:44:28
我只想要:2004-8-11 】<%# DataBinder.Eval(Container.DataItem,"Company_Ureg_Date","{0:yyyy-M-d}")%>
应该如何改?
【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+$" />

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 = "<script language=\"JavaScript\">";
private static string ScriptEnd = "</script>";
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. 将时间格式化:string aa=DateTime.Now.ToString("yyyy年MM月dd日");
1.1 取当前年月日时分秒currentTime=System.DateTime.Now;
1.2 取当前年int 年= DateTime.Now.Year;
1.3 取当前月int 月= DateTime.Now.Month;
1.4 取当前日int 日= DateTime.Now.Day;
1.5 取当前时int 时= DateTime.Now.Hour;
1.6 取当前分int 分= DateTime.Now.Minute;
1.7 取当前秒int 秒= 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");
}
