0.用session判斷是否登陸
if(Session["login"] == null)
{
Response.Redirect("error.aspx");
}
1. 打開新的窗口并傳送參數: Button1.Attributes.Add("onclick","return confirm('確認?')"); button.attributes.add("onclick","if(confirm('are you sure...?')){return true;}else{return false;}") int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; 4.刪除表格記錄警告 } private void grdCustomer_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e) 6.表格超連接列傳遞參數 8.關于日期格式 日期格式設定 我覺得應該在itembound事件中 9.獲取錯誤信息并到指定頁面 //其余的非HttpUnhandledException異常交給asp.net自己處理就okay了 :) Redirect會導致post-back的產生從而丟失了錯誤信息,所以頁面導向應該直接在服務器端執行,這樣就可以在錯誤處理頁 //自定義異常處理類 namespace MyAppException public AppException(string message) public AppException(string message,Exception innerException) //日志記錄類 namespace MyEventLog WriteLog(TraceLevel.Error, message); /// <summary> WriteLog(TraceLevel.Warning, message); /// <summary> WriteLog(TraceLevel.Verbose, message); /// <summary> /// <summary> try EventLog eventLog = new EventLog("Application", ApplicationConfiguration.EventLogMachineName, ApplicationConfiguration.EventLogSourceName ); } onkeydown="if(event.keyCode==13) event.keyCode=9" http://xx/inc/delete.aspx?ID={0}" } 后臺代碼 protected void CheckAll_CheckedChanged(object sender, System.EventArgs e) 17.數字格式化 <%#Container.DataItem("price","{0:¥#,##0.00}")%> int i=123456; 18.日期格式化 【aspx頁面內:<%# DataBinder.Eval(Container.DataItem,"Company_Ureg_Date")%> <%# DataBinder.Eval(Container.DataItem,"Company_Ureg_Date","{0:yyyy-M-d}")%> 應該如何改? ^((/d{2}(([02468][048])|([13579][26]))[/-///s]?((((0?[13578])|(1[02]))[/-///s]?((0?[1-9])|([1-2][0-9])| B.以下正確的輸入格式:[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]))$ HttpUtility.HtmlEncode(string); 19.如何設定全局變量 Application_Start()事件中 添加Application[屬性名] = xxx; 就是你的全局變量 20.怎樣作到HyperLinkColumn生成的連接后,點擊連接,打開新窗口? HyperLinkColumn有個屬性Target,將器值設置成"_blank"即可.(Target="_blank") 【ASPNETMENU】點擊菜單項彈出新窗口 21.委托討論 22.讀取DataGrid控件TextBox值 foreach(DataGrid dgi in yourDataGrid.Items) 23.在DataGrid中有3個模板列包含Textbox分別為 DG_ShuLiang (數量) DG_DanJian(單價) DG_JinE(金額)分別在5.6.7列,要求在錄入數量及單價的時候自動算出金額即:數量*單價=金額還要求錄入時限制為 數值型.我如何用客戶端腳本實現這個功能? 〖思歸〗 <asp:RegularExpressionValidator id="revS" runat="server" ControlToValidate="ShuLiang" ErrorMessage="must be integer" ValidationExpression="^/d+$" /> <asp:TemplateColumn HeaderText="單價"> <asp:RegularExpressionValidator id="revS2" runat="server" ControlToValidate="DanJian" ErrorMessage="must be numeric" ValidationExpression="^/d+(/./d*)?$" /> </ItemTemplate> <asp:TemplateColumn HeaderText="金額"> <script language="javascript"> var q = txts[txts.length-3].value; if (isNaN(q) || isNaN(p)) q = parseInt(q); txts[txts.length-1].value = (q * p).toFixed(2); 25.在Datagrid中修改數據,當點擊編輯鍵時,數據出現在文本框中,怎么控制文本框的大小 ? private void DataGrid1_ItemDataBound(obj sender,DataGridItemEventArgs e) } public static void ConfirmMessageBox(string PageTarget,string Content) string ConfirmContent="var retvalue="/blog/window.confirm('"+Content+"');"+"if(retValue){window.location="'"+PageTarget+"';}"; ConfirmContent=ScriptBegin + ConfirmContent + ScriptEnd; Page ParameterPage = (Page)System.Web.HttpContext.Current.Handler; }
傳送參數:
response.write("<scr
接收參數:
string a = Request.QueryString("id");
string b = Request.QueryString("id1");
2.為按鈕添加對話框
3.刪除表格選定記錄
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString()
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('您是否確定要刪除這條信息');");
break;
default:
break;
}
5.點擊表格行鏈接另一頁
{
//點擊表格打開
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 + "');");
}
雙擊表格連接到另一頁
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 + "'");
}
雙擊表格打開新一頁
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 + "')");
}
★特別注意:【?id=】 處不能為 【?id =】
<asp:HyperLinkColumn Target="_blank" headertext="ID號" DataTextField="id" NavigateUrl="aaa.aspx?id='<%# DataBinder.Eval(Container.DataItem, "數據字段1")%>' & name='<%# DataBinder.Eval(Container.DataItem, "數據字段2")%>' />
7.表格點擊改變顏色
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';");
}
寫在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='';");
}
DataFormatString="{0:yyyy-MM-dd}"
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd"))
不要使用Response.Redirect,而應該使用Server.Transfer
e.g
// in global.asax
protected void application_Error(Object sender, EventArgs e) {
if (Server.GetLastError() is HttpUnhandledException)
Server.Transfer("MyErrorPage.aspx");
}
面得到出錯信息并進行相應的處理
10.清空Cookie
Cookie.Expires=[DateTime];
Response.Cookies("UserName").Expires = 0
11.自定義異常處理
using System;
using System.Diagnostics;
{
/// <summary>
/// 從系統異常類ApplicationException繼承的應用程序異常處理類。
/// 自動將異常內容記錄到Windows NT/2000的應用程序日志
/// </summary>
public class AppException:System.ApplicationException
{
public AppException()
{
if (ApplicationConfiguration.EventLogEnabled)
LogEvent("出現一個未知錯誤。");
}
{
LogEvent(message);
}
{
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;
{
/// <summary>
/// 事件日志記錄類,提供事件日志記錄支持
/// <remarks>
/// 定義了4個日志記錄方法 (error, warning, info, trace)
/// </remarks>
/// </summary>
public class ApplicationLog
{
/// <summary>

/// </summary>
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();
}
/// 實際事件日志寫入方法
/// <param name="level">要記錄信息的級別(error,warning,info,trace).</param>

/// </summary>
private static void WriteLog(TraceLevel level, String messageText)
{
{
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;
}
//寫入事件日志
eventLog.WriteEntry(messageText, LogEntryType);
catch {} //忽略任何異常
}
} //class ApplicationLog
}
12.Panel 橫向滾動,縱向自動擴展
<asp:panel style="overflow-x:scroll;overflow-y:auto;"></asp:panel>
13.回車轉換成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>
15.DataGrid行隨鼠標變色
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="選中">
<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>
{
//改變列的選定,實現全選或全不選。
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;
}
}
}
【<%#Container.DataItem("price")%>的結果是500.0000,怎樣格式化為500.00?】
string s=i.ToString("###,###.00");
顯示為: 2004-8-11 19:44:28
我只想要:2004-8-11 】
【格式化日期】
取出來,一般是object
((DateTime)objectFromDB).ToString("yyyy-MM-dd");
【日期的驗證表達式】
A.以下正確的輸入格式: [2004-2-29], [2004-02-29 10:29:39 pm], [2004/12/31]
(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})))?$
【大小寫轉換】
HttpUtility.HtmlDecode(string)
Global.asax中
在你的menuData.xml文件的菜單項中加入URLTarget="_blank"
如:
<?xml version="1.0" encoding="GB2312"?>
<MenuData ImagesBaseURL="images/">
<MenuGroup>
<MenuItem Label="內參信息" URL="Infomation.aspx" >
<MenuGroup ID="BBC">
<MenuItem Label="公告信息" URL="Infomation.aspx" URLTarget="_blank" LeftIcon="file.gif"/>
<MenuItem Label="編制信息簡報" URL="NewInfo.aspx" LeftIcon="file.gif" />
......
最好將你的aspnetmenu升級到1.2版

http://dev.csdn.net/develop/article/22/22951.shtm
{
TextBox tb = (TextBox)dgi.FindControl("yourTextBoxId");
tb.Text....
}
<asp:TemplateColumn HeaderText="數量">
<ItemTemplate>
<asp:TextBox id="ShuLiang" runat='server' Text='<%# DataBinder.Eval(Container.DataItem,"DG_ShuLiang")%>'
onkeyup="Javascript:DoCal()"
/>
</ItemTemplate>
</asp:TemplateColumn>
<ItemTemplate>
<asp:TextBox id="DanJian" runat='server' Text='<%# DataBinder.Eval(Container.DataItem,"DG_DanJian")%>'
onkeyup="javascript:DoCal()"
/>
</asp:TemplateColumn>
<ItemTemplate>
<asp:TextBox id="JinE" runat='server' Text='<%# DataBinder.Eval(Container.DataItem,"DG_JinE")%>' />
</ItemTemplate>
</asp:TemplateColumn>
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 p = txts[txts.length-2].value;
return;
p = parseFloat(p);
}
</script>
24.datagrid選定比較底下的行時,為什么總是刷新一下,然后就滾動到了最上面,剛才選定的行因屏幕的關系就看不到了
page_load
page.smartNavigation=true
{
for(int i=0;i<e.Item.Cells.Count-1;i++)
if(e.Item.ItemType==ListItemType.EditType)
{
e.Item.Cells.Attributes.Add("Width", "80px")
}
26.對話框
private static string ScriptBegin = "<script language=/"JavaScript/">";
private static string ScriptEnd = "</script>";
{
ParameterPage.RegisterStartupScript("confirm",ConfirmContent);
//Response.Write(strScript);
