收集的一些综合功能函数

下载文件出现提示框或者直接显示在浏览器中

出现提示框

string strFile="F:""a.doc";//路径根据实际情况而定

if(!System.IO.File.Exists(strFile))

{

Response.Write("<script language='javascript'>alert('对不起，文件不存在！');</script>");

return;

}

Response.Clear();

Response.ClearHeaders();

Response.Charset = "GB2312";

Response.ContentEncoding =System.Text.Encoding.UTF8;

Response.ContentType = "application/octet-stream";

FileInfo fi=new FileInfo(strFile);

Response.AddHeader("Content-Disposition","attachment; filename=" + HttpUtility.UrlEncode(fi.Name)) ;

Response.AddHeader("Content-Length",fi.Length.ToString());

byte[] tmpbyte=new byte[1024*8];

FileStream fs=fi.OpenRead();

int count;

while((count=fs.Read(tmpbyte,0,tmpbyte.Length))>0)

{

Response.BinaryWrite(tmpbyte);

Response.Flush();

}

fs.Close();

Response.End();

直接在浏览器中打开

string strFile="F:""a.doc";//路径根据实际情况而定

Response.Clear();

Response.ClearHeaders();

Response.Charset = "GB2312";

Response.ContentEncoding =System.Text.Encoding.UTF8;

Response.ContentType = "application/msword";

Response.WriteFile(strFile);

Window.open()打开一个窗体不被拦截

在DataGrid中建一个模板列，在模板列中放一个客户端的Button,或者直接写你要的字句，然后用<a href>连接

例：

<TABLE id="Table1" cellSpacing="0" cellPadding="0" width="100%" align="center" border="0">

<TR>

<TD width="100%">

<asp:datagrid id="dgFreightInfo" runat="server" Width="96%" GridLines="Horizontal" AllowCustomPaging="True"

AllowPaging="True" AutoGenerateColumns="False" DataKeyField="id" BorderColor="White" BorderWidth="1px"

PageSize="20">

<ItemStyle Height="25px" BackColor="#F7F7F7"></ItemStyle>

<HeaderStyle Font-Bold="True" HorizontalAlign="Center" Height="25px" BackColor="#E8E8E8"></HeaderStyle>

<Columns>

<asp:TemplateColumn>

<ItemTemplate>

<A href='javascript:onclick=LoadFreight(<%# DataBinder.Eval(Container,"DataItem.id")%>)'>

详细信息</A>

</ItemTemplate>

</asp:TemplateColumn>

</Columns>

</asp:datagrid>

</TD>

</TR>

然后写一个JavaScript方法

<script language="javascript">

function LoadFreight(id)//id为传进的参数

{

var url='url.aspx?tid='+id+'';

window.open(url,'','scrollbars=yes,top=0,left=0,resizable=no,status=no,toolbar=no,menubar=no,location=no,width=430,height=600');

}

</script>

1. 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 + "')");

}

★特别注意：【?id=】 处不能为 【?id =】

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

/// </summary>

public class AppException:System.ApplicationException

{

public AppException()

{

if (ApplicationConfiguration.EventLogEnabled)

LogEvent("出现一个未知错误。");

}

public AppException(string message)

{

LogEvent(message);

}

public AppException(string message,Exception innerException)

{

LogEvent(message);

if (innerException != null)

{

LogEvent(innerException.Message);

}

}

//日志记录类

LogEntryType = EventLogEntryType.Error;

break;

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

<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>

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

http://dotnet.aspx.cc/exam/enter2tab.aspx

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

【<%#Container.DataItem("price")%>的结果是500.0000，怎样格式化为500.00?】

<%#Container.DataItem("price","{0:￥#,##0.00}")%>

int i=123456;

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

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.委托讨论

http://dev.csdn.net/develop/article/22/22951.shtm

22.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 = "<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);

}

一．显示消息对话框类
做项目时总免不了要弹出对话框，或提示用户，或做用户确认。像WinForm下的MessageBox一样很方便，但web下是不是也可以实现呢，答案是肯定的，我简单总结了一下并封装到类，在项目里像WinForm的MessageBox那样直接调用就可以，也可以把它编译成dll作为组件直接调用，并且它也没有弹出对话框时的大白屏现象：）。
///<summary>
///显示消息提示对话框。
///李天平

public class MessageBox
{
private MessageBox()
{
}
///<summary>

///<param name="page">当前页面指针，一般为this</param>
///<param name="msg">提示信息</param>
public static void Show(System.Web.UI.Page page,string msg)
{
page.RegisterStartupScript("message","<script language='javascript' defer>alert('"+msg.ToString()+"');</script>");
}
///<summary>

public static void ShowConfirm(System.Web.UI.WebControls.WebControl Control,string msg)
{
//Control.Attributes.Add("onClick","if (!window.confirm('"+msg+"')){return false;}");
Control.Attributes.Add("onclick", "return confirm('" + msg + "');") ;
}
///<summary>
///显示消息提示对话框，并进行页面跳转

///<param name="url">跳转的目标URL</param>
public static void ShowAndRedirect(System.Web.UI.Page page,string msg,string url)
{
StringBuilder Builder=new StringBuilder();
Builder.Append("<script language='javascript' defer>");
Builder.AppendFormat("alert('{0}');",msg);
Builder.AppendFormat("top.location.href='{0}'",url);
Builder.Append("</script>");
page.RegisterStartupScript("message",Builder.ToString());

}
///<summary>
///输出自定义脚本信息
///</summary>
///<param name="page">当前页面指针，一般为this</param>
///<param name="script">输出脚本</param>
public static void ResponseScript(System.Web.UI.Page page,string script)
{
page.RegisterStartupScript("message","<script language='javascript' defer>"+script+"</script>");
}
}

二．页面数据验证类

做项目，特别做MIS，更避免不了有用户输入数据需要做有效性验证，这里我总结封装了一个页面数据校验的工具类，用起来也是很方便。
///<summary>
///页面数据校验类

private static Regex RegDecimalSign = new Regex("^[+-]?[0-9]+[.]?[0-9]+$"); //等价于^[+-]?"d+[.]?"d+$
private static Regex RegEmail = new Regex("^[""w-]+@[""w-]+"".(com|net|org|edu|mil|tv|biz|info)$");//w 英文字母或数字的字符串，和 [a-zA-Z0-9] 语法一样
