1. 打开新的窗口并传送参数: z:ru68
$nGbT4sc
传送参数: Vq\..!y
response.write("<script>window.open(’*.aspx?id="+this.DropDownList1.SelectIndex+"&id1="+...+"’)</script>") \U)2

@yU!sE:
接收参数: h}anTFKP
string a = Request.QueryString("id"); w-0O j
string b = Request.QueryString("id1"); RvyBg:Aj5

2.为按钮添加对话框 Ie^Dn!0S
Button1.Attributes.Add("onclick","return confirm(’确认?’)"); W%cj39$
button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") LH3N}J({
0p:ClM2O
3.删除表格选定记录 e6{[o@aM{
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; \J,- <wF
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() xY\*L:TwW

if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem) qOcG|UgF

8.关于日期格式 S!I <m&Cgc
vU$O{|J
日期格式设定 qs
c-e,rl
DataFormatString="{0:yyyy-MM-dd}" #Lxj
)
0m+5Zn
我觉得应该在itembound事件中 ~g4rGz
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) Q5Ghki

9.获取错误信息并到指定页面 XM@-Y&c$A
.f92^lu9
不要使用Response.Redirect,而应该使用Server.Transfer EkjK92cF
/<?X-IDz.{
e.g m"|(w`n]E+
// in global.asax 2`FsG/o\T~
protected void Application_Error(Object sender, EventArgs e) { dT,m{[+
if (Server.GetLastError() is HttpUnhandledException) S~a:1
_Wl
Server.Transfer("MyErrorPage.aspx"); WH*=81)zp
ZvnZ}t>?
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) eR*
]<0=
} #`#aSqGmc
dW^_tzfF7
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 oIL+@}u7
