1. 打开新的窗口并传送参数: gatxvR7H

传送参数: ~X%W2N2
response.write("<script>window.open(’*.aspx?id="+this.DropDownList1.SelectIndex+"&id1="+...+"’)</script>") !vH={40 ]
UaV8!Z>
接收参数: ETtoY<`#
string a = Request.QueryString("id"); m15> ^i^W
string b = Request.QueryString("id1"); wGAeOD

2.为按钮添加对话框 )>8 k8E
Button1.Attributes.Add("onclick","return confirm(’确认?’)"); ,kw:g&A
button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") C'xWRSDO

3.删除表格选定记录 glgXSOj

string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() FpFkZFtG'm

6.表格超连接列传递参数 muKCCWy#

8.关于日期格式 W@FRKDixG
~Op~~
m
日期格式设定 |]'0z0>
DataFormatString="{0:yyyy-MM-dd}" C}8 3t~Q
k~HS_b*]d
我觉得应该在itembound事件中 gtlyQ
_V
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) ?)L X4GY
]q CCCI`
9.获取错误信息并到指定页面 ^F4h:
bA8RoC
不要使用Response.Redirect,而应该使用Server.Transfer JPGEE1!B{b
1_0\_|
e.g kH }HFl
// in global.asax
:to1%6
protected void Application_Error(Object sender, EventArgs e) { w!~85""
if (Server.GetLastError() is HttpUnhandledException) DZ5QC aA
Server.Transfer("MyErrorPage.aspx"); v"J7VF2
"Iwd-#;$;
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) i*2l4
} #xBh62yIuP
2(iv+<t
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 u RPvo}!=1

10.清空Cookie *e}1KcJ
Cookie.Expires=[DateTime]; -G@:uxB
Response.Cookies("UserName").Expires = 0 _rj B.
