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:onclick=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>

12.Panel 横向滚动，纵向自动扩展
<asp:panel style="overflow-x:scroll;overflow-y:auto;"></asp:panel>
13.回车转换成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>
onkeydown="if(event.keyCode==13) event.keyCode=9"
http://dotnet.aspx.cc/exam/enter2tab.aspx
14.DataGrid超级连接列
DataNavigateUrlField="字段名" DataNavigateUrlformatString="http://xx/inc/delete.aspx?ID={0}"
15.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"+"""");
}
}
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="选中">
<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>
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("chkExport");
chkExport.Checked = true;
}
}
else
{
foreach(DataGridItem oDataGridItem in MyDataGrid.Items)
{
chkExport = (CheckBox)oDataGridItem.FindControl("chkExport");
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
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")%>'
onkeyup="javascript:DoCal()"
/>
<asp:RegularExpressionValidator id="revS" runat="server" ControlToValidate="ShuLiang" ErrorMessage="must be integer" ValidationExpression="^"d+$" />
</ItemTemplate>
</asp:TemplateColumn>
<asp:TemplateColumn HeaderText="单价">
<ItemTemplate>
<asp:TextBox id="DanJian" runat='server' Text='<%# DataBinder.Eval(Container.DataItem,"DG_DanJian")%>'
onkeyup="javascript:DoCal()"
/>
<asp:RegularExpressionValidator id="revS2" runat="server" ControlToValidate="DanJian" ErrorMessage="must be numeric" ValidationExpression="^"d+("."d*)?$" />
</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;
var row = e.parentNode.parentNode;
var txts = row.all.tags("INPUT");
if (!txts.length || txts.length < 3)
return;
var q = txts[txts.length-3].value;
var p = txts[txts.length-2].value;
if (isNaN(q) || isNaN(p))
return;
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

public class MessageBox
{
private MessageBox()
{
}
///<summary>

///</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

{
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
