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"); |
2.为按钮添加对话框
Button1.Attributes.Add("onclick","return confirm(’确认?’)"); |
3.删除表格选定记录
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; |
4.删除表格记录警告
private void DataGrid_ItemCreated(Object sender,DataGridItemEventArgs e) |
5.点击表格行链接另一页
private void grdCustomer_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e) |
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) |
双击表格打开新一页
if(e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem) |
6.表格超连接列传递参数
<asp:HyperLinkColumn Target="_blank" headertext="ID号" DataTextField="id" NavigateUrl="aaa.aspx?id=’ |
7.表格点击改变颜色
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) |
写在DataGrid的_ItemDataBound里
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) |
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 |
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]; |
11.自定义异常处理
//自定义异常处理类 |
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"> |
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) |
16.模板列
<ASP:TEMPLATECOLUMN visible="False" sortexpression="demo" headertext="ID"> |
后台代码
protected void CheckAll_CheckedChanged(object sender, System.EventArgs e) |
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}")%> |
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); |
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"?> |
最好将你的aspnetmenu升级到1.2版
21.读取DataGrid控件TextBox值
foreach(DataGrid dgi in yourDataGrid.Items) |
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"> |
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 |
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) |
26.对话框
private static string ScriptBegin = "<script language=\"JavaScript\">"; |
27. 将时间格式化:string aa=DateTime.Now.ToString("yyyy年MM月dd日");
1.1 取当前年月日时分秒
currentTime=System.DateTime.Now; |
1.2 取当前年
int 年= DateTime.Now.Year; |
1.3 取当前月
int 月= DateTime.Now.Month; |
1.4 取当前日
int 日= DateTime.Now.Day; |
1.5 取当前时
int 时= DateTime.Now.Hour; |
1.6 取当前分
int 分= DateTime.Now.Minute; |
1.7 取当前秒
int 秒= DateTime.Now.Second; |
1.8 取当前毫秒
int 毫秒= DateTime.Now.Millisecond; |
28.自定义分页代码:
先定义变量:
public static int pageCount; //总页面数 |
下一页:
if(DataGrid1.CurrentPageIndex < (DataGrid1.PageCount - 1)) |
上一页:
if(DataGrid1.CurrentPageIndex >0) |
直接页面跳转:
int a=int.Parse(JumpPage.Value.Trim());//JumpPage.Value.Trim()为跳转值 |
29.DataGrid使用:
添加删除确认:
private void DataGrid1_ItemCreated(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e) |
样式交替:
ListItemType itemType = e.Item.ItemType; |
添加一个编号列:
DataTable dt= c.ExecuteRtnTableForAccess(sqltxt); //执行sql返回的DataTable |
DataGrid1中添加一个CheckBox,页面中添加一个全选框
private void CheckBox2_CheckedChanged(object sender, System.EventArgs e) |
将当前页面中DataGrid1显示的数据全部删除
foreach(DataGridItem thisitem in DataGrid1.Items) |
30.当文件在不同目录下,需要获取数据库连接字符串(如果连接字符串放在Web.config,然后在Global.asax中初始化)
在Application_Start中添加以下代码:
Application["ConnStr"]=this.Context.Request.PhysicalApplicationPath+ConfigurationSettings. |
31.变量.ToString()
字符型转换转为字符串
12345.ToString("n"); //生成 12,345.00 |
32、变量.Substring(参数1,参数2);
截取字串的一部分,参数1为左起始位数,参数2为截取几位。如:string s1 = str.Substring(0,2);
33.在自己的网站上登陆其他网站:(如果你的页面是通过嵌套方式的话,因为一个页面只能有一个FORM,这时可以导向另外一个页面再提交登陆信息)
<SCRIPT language="javascript"> |
文本框的名称必须是你要登陆的网页上的名称,如果源码不行可以用vsniffer 看看。
下面是获取用户输入的登陆信息的代码:
string name; |
最近公司在做一个系统,要用一个时间选择控件,本来是用ASP。NET来做,但最后我就用JS来写
