- <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’;");
- }
复制代码 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=’’;");
- }
复制代码 8.关于日期格式
日期格式设定
- DataFormatString="{0:yyyy-MM-dd}"
复制代码 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"))
复制代码 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");
复制代码 //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
复制代码 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
- using System;
- using System.Configuration;
- using System.Diagnostics;
- using System.IO;
- using System.Text;
- using System.Threading;

- 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();
- }
- /// <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>

- private static void WriteLog(TraceLevel level, String messageText)

- catch {} //忽略任何异常
