3.删除表格选定记录 %&NK|M+n

string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() C\K--

6.表格超连接列传递参数 Je/R'QP^8

e.Item.Attributes.Add("onmouseout","this.style.backgroundColor=’’;this.style.color=’’;"); }&=C*5JN

8.关于日期格式 TY?Fs-
p%}oo#%J
日期格式设定 qLR)>$
DataFormatString="{0:yyyy-MM-dd}" pvX\kX3}
LB>!%Vx
我觉得应该在itembound事件中 v8LKv`I's
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) |[*b[O
1W
B"G;"X
9.获取错误信息并到指定页面 smSUo/
6%)dsTAB
不要使用Response.Redirect,而应该使用Server.Transfer 4h-y'&Z
C\1Dy5
e.g $Q62
7
// in global.asax /
JlUqC
protected void Application_Error(Object sender, EventArgs e) { f;QWlh"9
if (Server.GetLastError() is HttpUnhandledException) (|S e+Y#e,
Server.Transfer("MyErrorPage.aspx"); Up8#Nz
T
LdA&F&
pI
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) 0%v
p'v
} O<fbO7.-
m#Rll[
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 CT/`Kg_

10.清空Cookie MwiT1sB~
Cookie.Expires=[DateTime]; |Kb-oM&^#
Response.Cookies("UserName").Expires = 0 Zx3m$.8
