1.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")%>' />
2.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='';");
- }
3.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"))
4.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
-
-
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。
5.清空Cookie
- Cookie.Expires=[DateTime];
-
Response.Cookies("UserName").Expires = 0
6.自定义异常处理
-
-
using System;
-
using System.Diagnostics;
-
namespace MyAppException
- {
-
-
-
-
-
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);
- }
- }
- }
- }
-
-
using System;
-
using System.Configuration;
-
using System.Diagnostics;
-
using System.IO;
-
using System.Text;
-
using System.Threading;
-
namespace MyEventLog
- {
-
-
-
-
-
-
-
public class ApplicationLog
- {
-
-
-
-
-
public static void WriteError(String message){
- WriteLog(TraceLevel.Error, message);
- }
-
-
-
-
-
public static void WriteWarning(String message){
- WriteLog(TraceLevel.Warning, message);
- }
-
-
-
-
-
public static void WriteInfo(String message){
- WriteLog(TraceLevel.Info, message);
- }
-
-
-
-
-
public static void WriteTrace(String message){
- WriteLog(TraceLevel.Verbose, message);
- }
-
-
-
-
-
-
-
-
-
public static String FormatException(Exception ex, String catchInfo){
-
StringBuilder strBuilder = new StringBuilder();
-
if (catchInfo != String.Empty){
-
strBuilder.Append(catchInfo).Append("/r/n");
- }
-
strBuilder.Append(ex.Message).Append("/r/n").Append(ex.StackTrace);
-
return strBuilder.ToString();
- }
-
-
-
-
-
-
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.Info:
- LogEntryType = EventLogEntryType.Information;
-
break;
-
case TraceLevel.Verbose:
- LogEntryType = EventLogEntryType.SuccessAudit;
-
break;
-
default:
- LogEntryType = EventLogEntryType.SuccessAudit;
-
break;
- }
-
EventLog eventLog = new EventLog("Application", ApplicationConfiguration.EventLogMachineName, ApplicationConfiguration.EventLogSourceName );
-
- eventLog.WriteEntry(messageText, LogEntryType);
- }
-
catch {}
- }
-
}
- }
7.Panel 横向滚动,纵向自动扩展
-
<asp:panel style="overflow-x:scroll;overflow-y:auto;"></asp:panel>
8.回车转换成Tab
(1)
-
<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>
(2)当在有keydown事件的控件上敲回车时,变为tab
-
public void Tab(System.Web .UI.WebControls .WebControl webcontrol) {
-
webcontrol.Attributes .Add ("onkeydown", "if(event.keyCode==13) event.keyCode=9");
-
}
9.DataGrid超级连接列
-
DataNavigateUrlField="字段名"DataNavigateUrlFormatString="http://xx/inc/delete.aspx?ID={0}"
10.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"+"/"");
- }
- }
11.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" horiz></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)
- {
-
- 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;
- }
- }
- }
12.数字格式化
-
<%#Container.DataItem("price")%>
-
<%#Container.DataItem("price","{0:¥#,##0.00}")%>
-
int i=123456;
-
string s=i.ToString("###,###.00");
13.日期格式化
-
-
<%# DataBinder.Eval(Container.DataItem,"Company_Ureg_Date")%>
-
-
-
<%# DataBinder.Eval(Container.DataItem,"Company_Ureg_Date","{0:yyyy-M-d}")%>
-
-
-
-
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);
14.如何设定全局变量
Global.asax中
Application_Start()事件中
添加
就是你的全局变量
15.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。
