1. 打开新的窗口并传送参数: Jc:*X4-'

接收参数: lRX*\M\`
string a = Request.QueryString("id"); UvxJ _
string b = Request.QueryString("id1"); qP *$wKY,

2.为按钮添加对话框 ?UQE;0 B

8.关于日期格式 xWWfts1t
( >zXapb2
日期格式设定 SUsD)!u_H
DataFormatString="{0:yyyy-MM-dd}" OiH

tz\7,yGT
我觉得应该在itembound事件中 rs2G{a
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) D ksSD

9.获取错误信息并到指定页面 %p6"Sg*
;A7HEx
不要使用Response.Redirect,而应该使用Server.Transfer gq~>S1
vU0j!XqE
e.g c-.t8X,5(~
// in global.asax "PK\;#[W|
protected void Application_Error(Object sender, EventArgs e) { teH $hd-q
if (Server.GetLastError() is HttpUnhandledException) Bh$hgf.C
Server.Transfer("MyErrorPage.aspx"); +a_eNl,
ig:,: KN
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) 25]Mi2_
} k_?xiOSh
;S5*n:d
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 H)S" `j
