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:οnclick=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。");

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://community.csdn.net/Expert/topic/2651/2651579.xml?temp=.7183191 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")%>' οnkeyup="javascript:DoCal()" /> <asp:RegularExpressionValidator id="revS" runat="server" ControlToValidate="ShuLiang" ErrorMessage="must be integer" ValidationExpression="^\d+$" /> </ItemTemplate> </asp:TemplateColumn> <asp:TemplateColumn HeaderText="单价"> <ItemTemplate> <asp:TextBox id="DanJian" runat='server' Text='<%# DataBinder.Eval(Container.DataItem,"DG_DanJian")%>' οnkeyup="javascript:DoCal()" /> <asp:RegularExpressionValidator id="revS2" runat="server" ControlToValidate="DanJian" ErrorMessage="must be numeric" ValidationExpression="^\d+(\.\d*)?$" /> </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;

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

/// 2005.10.1

/// </summary>

public class MessageBox

{

private MessageBox()

{

}

/// <summary>

/// 显示消息提示对话框

/// </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>

/// 控件点击消息确认提示框

/// </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 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

/// </summary>

/// <param name="page">当前页面指针，一般为this</param>

/// <param name="msg">提示信息</param>

/// <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

/// 李天平

/// 2004.8

/// </summary>

public class PageValidate

{

private static Regex RegNumber = new Regex("^[0-9]+$");

private static Regex RegNumberSign = new Regex("^[+-]?[0-9]+$");

private static Regex RegDecimal = new Regex("^[0-9]+[.]?[0-9]+$");

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

private static Regex RegCHZN = new Regex("[\u4e00-\u9fa5]");

public PageValidate()

{

}
