  this.Response.Write(t.ToString());

11.//获取" . "后面的字符


i.ToString().Trim().Substring(i.ToString().Trim().LastIndexOf(&quot;.&quot;)

+1).ToLower().Trim()


12. 打开新的窗口并传送参数:
  传送参数:

response.write(&quot;<script>window.open(’*.aspx?

id=&quot;+this.DropDownList1.SelectIndex+&quot;&amp;id1=&quot;+...+&quot;’)<

/script>&quot;)

接收参数:

string a = Request.QueryString(&quot;id&quot;);

12.为按钮添加对话框


Button1.Attributes.Add(&quot;onclick&quot;,&quot;return confirm(’确认?’)

&quot;);
button.attributes.add(&quot;onclick&quot;,&quot;if(confirm(’are you sure...?

’)){return true;}else{return false;}&quot;)

13.删除表格选定记录


int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex];
string deleteCmd = &quot;Delete from Employee where emp_id = &quot; +

intEmpID.ToString()

14.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(&quot;onclick&quot;,&quot;return confirm(’

您是否确定要删除这条信息’);&quot;);
  break;
  default:
  break;
  }
}

15.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(&quot;onclick&quot;,&quot;window.open(’

Default.aspx?id=&quot; + e.Item.Cells[0].Text + &quot;’);&quot;);
}


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(&quot;ondblclick&quot;,

&quot;location.href=’../ShippedGrid.aspx?id=&quot; + orderItemID + &quot;’

&quot;);
}

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(&quot;ondblclick&quot;, &quot;open

(’../ShippedGrid.aspx?id=&quot; + orderItemID + &quot;’)&quot;);
}

16.表格超连接列传递参数

<asp:HyperLinkColumn Target=&quot;_blank&quot; headertext=&quot;ID号&quot;

DataTextField=&quot;id&quot; NavigateUrl=&quot;aaa.aspx?id=’
  <%# DataBinder.Eval(Container.DataItem, &quot;数据字段1&quot;)%>’ &amp;

name=’<%# DataBinder.Eval(Container.DataItem, &quot;数据字段2&quot;)%>’ /


17.表格点击改变颜色


if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType ==

ListItemType.AlternatingItem)
{
  e.Item.Attributes.Add

(&quot;onclick&quot;,&quot;this.style.backgroundColor=’#99cc00’;
    this.style.color=’buttontext’;this.style.cursor=’default’;&quot;);
}

写在DataGrid的_ItemDataBound里


if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType ==

ListItemType.AlternatingItem)
{
e.Item.Attributes.Add

(&quot;onmouSEOver&quot;,&quot;this.style.backgroundColor=’#99cc00’;
  this.style.color=’buttontext’;this.style.cursor=’default’;&quot;);
e.Item.Attributes.Add(&quot;onmouseout&quot;,&quot;this.style.backgroundColor=

’’;this.style.color=’’;&quot;);
}

18.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"))
19.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(&quot;MyErrorPage.aspx&quot;);

//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
20.清空Cookie

Cookie.Expires=[DateTime];
Response.Cookies(&quot;UserName&quot;).Expires = 0

 

 

 


21.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(&quot;出现一个未知错误。&quot;);
  }
  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;
  namespace MyEventLog
  {
  /// <summary>
  /// 事件日志记录类,提供事件日志记录支持
  /// <remarks>
  /// 定义了4个日志记录方法 (error, warning, info, trace)
  /// </remarks>
  /// </summary>
  public class ApplicationLog
  {
  /// <summary>
  /// 将错误信息记录到Win2000/NT事件日志中

  /// </retvalue>
  /// </summary>
  public static String FormatException(Exception ex, String catchInfo)
  {
  StringBuilder strBuilder = new StringBuilder();
  if (catchInfo != String.Empty)
  {
  strBuilder.Append(catchInfo).Append(&quot;\r\n&quot;);
  }
  strBuilder.Append(ex.Message).Append(&quot;\r\n&quot;).Append(ex.StackTrace);
  return strBuilder.ToString();
  }
  /// <summary>
  /// 实际事件日志写入方法
  /// <param name=&quot;level&quot;>要记录信息的级别(error,warning,info,trace).</param>
  /// <param name=&quot;messageText&quot;>要记录的文本.</param>
  /// </summary>
  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(&quot;Application&quot;, ApplicationConfiguration.EventLogMachineName, ApplicationConfiguration.EventLogSourceName );
  //写入事件日志
  eventLog.WriteEntry(messageText, LogEntryType);
  }
  catch {} //忽略任何异常
  }
  } //class ApplicationLog
}


22.Panel 横向滚动,纵向自动扩展


<asp:panel style=&quot;overflow-x:scroll;overflow-y:auto;&quot;></asp:panel>


23.回车转换成Tab
(1)


<script language=&quot;javascript&quot; for=&quot;document&quot; event=&quot;onkeydown&quot;>
  if(event.keyCode==13 &amp;&amp; event.srcElement.type!=’button’ &amp;&amp; event.srcElement.type!=’submit’ &amp;&amp;     event.srcElement.type!=’reset’ &amp;&amp; event.srcElement.type!=’’&amp;&amp; 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 (&quot;onkeydown&quot;, &quot;if(event.keyCode==13) event.keyCode=9&quot;);
}
24.DataGrid超级连接列
DataNavigateUrlField=&quot;字段名&quot; DataNavigateUrlFormatString=&quot;http://xx/inc/delete.aspx?ID={0}&quot;


25.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( &quot;onmouseout&quot;,&quot;this.style.backgroundColor=\&quot;&quot;+e.Item.Style[&quot;BACKGROUND-COLOR&quot;]+&quot;\&quot;&quot;);
  e.Item.Attributes.Add( &quot;onmouseover&quot;,&quot;this.style.backgroundColor=\&quot;&quot;+ &quot;#EFF3F7&quot;+&quot;\&quot;&quot;);
  }
}


26.模板列


<ASP:TEMPLATECOLUMN visible=&quot;False&quot; sortexpression=&quot;demo&quot;

headertext=&quot;ID&quot;>
<ITEMTEMPLATE>
<ASP LABEL text=’<%# DataBinder.Eval(Container.DataItem,

&quot;ArticleID&quot;)%>’ runat=&quot;server&quot; width=&quot;80%&quot;

id=&quot;lblColumn&quot; />
</ITEMTEMPLATE>
</ASP:TEMPLATECOLUMN>
<ASP:TEMPLATECOLUMN headertext=&quot;选中&quot;>
<HEADERSTYLE wrap=&quot;False&quot; horiz></HEADERSTYLE>
<ITEMTEMPLATE>
<ASP:CHECKBOX id=&quot;chkExport&quot; runat=&quot;server&quot; />
</ITEMTEMPLATE>
<EDITITEMTEMPLATE>
<ASP:CHECKBOX id=&quot;chkExportON&quot; runat=&quot;server&quot;

enabled=&quot;true&quot; />
</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(&quot;chkExport&quot;);
  chkExport.Checked = true;
  }
  }
  else
  {
  foreach(DataGridItem oDataGridItem in MyDataGrid.Items)
  {
  chkExport = (CheckBox)oDataGridItem.FindControl(&quot;chkExport&quot;);
  chkExport.Checked = false;
  }
  }
}
