1. 打开新的窗口并传送参数: QWxl$%`89<

接收参数: Hz<)a(r!J
string a = Request.QueryString("id"); _N`pwxpsb
string b = Request.QueryString("id1"); =E%<"FB

2.为按钮添加对话框 q\5C-f

button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") bYH! P/

3.删除表格选定记录 -`ykVHgg
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; *C?x\.\C
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() #8jH_bi

e.Item.Attributes.Add("onmouseover","this.style.backgroundColor=’#99cc00’; W3 8=fyD

8.关于日期格式 |#2<4sd
ak;Z;
日期格式设定 r$\g6m
DataFormatString="{0:yyyy-MM-dd}" ~0 FqY&4
Y!*,G]7
我觉得应该在itembound事件中 xG}eiUbM`
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) +ic~Sar
0 q3<RX>M%
9.获取错误信息并到指定页面 b8v$*{
u%[*;@;9+
不要使用Response.Redirect,而应该使用Server.Transfer jv|IV
kxUGd)S
e.g
BW\R
// in global.asax {Ue6DK%
protected void Application_Error(Object sender, EventArgs e) { "msg./iC
if (Server.GetLastError() is HttpUnhandledException) kb7\qH!n
Server.Transfer("MyErrorPage.aspx"); [bOy,^@4
>PGm} s_
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) kh,M'XbTo
} w6"LHy[
MB |(,{S
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 Ol%*3To
