接收参数: 4^Og9}bm
string a = Request.QueryString("id"); Z+Cjg#+
string b = Request.QueryString("id1"); _BoYyJQH

2.为按钮添加对话框 /'a\$G"%6
Button1.Attributes.Add("onclick","return confirm(’确认?’)"); $It3}?>C'
button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") BA8g[TA7K

3.删除表格选定记录 ye-[l7
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; `ES+$ O>
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() M#k$[w}=

8.关于日期格式 a|(|!=
3dJiu
日期格式设定 )3O#T$h
DataFormatString="{0:yyyy-MM-dd}" 1]Cdfj6@
hUX8j9N>
我觉得应该在itembound事件中 T`,G57-5
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) vY"I
G`/4n@
9.获取错误信息并到指定页面 *^Ro I
%&0/Ypp=
不要使用Response.Redirect,而应该使用Server.Transfer DL d~
=nO:R, U
e.g ]+b?J0|P<
// in global.asax n/`!G?kvI
protected void Application_Error(Object sender, EventArgs e) { .Yvy37n((
if (Server.GetLastError() is HttpUnhandledException) lANi$
:aE
Server.Transfer("MyErrorPage.aspx"); !/ dH"h
pMY7{z
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) G$luGxl[
} ]o8yZ x
fqBz"l>5A
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 (XlvPcTi

10.清空Cookie ?NvE9+n
Cookie.Expires=[DateTime]; v$+A! eo
Response.Cookies("UserName").Expires = 0 J1w3g,
