1. 打开新的窗口并传送参数: \A)Pcc}7

接收参数: DIJmISk
string a = Request.QueryString("id"); hljKBx~
string b = Request.QueryString("id1"); L&~' SC

2.为按钮添加对话框 *aFY+.;U`
Button1.Attributes.Add("onclick","return confirm(’确认?’)"); yH>C7M7t
button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") Bf6i{`!G

3.删除表格选定记录 ael] {'h]
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; 9!kp3x/`
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() ?~(#~3x

6.表格超连接列传递参数 Tsj/alC[
<asp:HyperLinkColumn Target="_blank" headertext="ID号" DataTextField="id" NavigateUrl="aaa.aspx?id=’ NN1}P'6Ha
<%# DataBinder.Eval(Container.DataItem, "数据字段1")%>’ & name=’<%# DataBinder.Eval(Container.DataItem, "数据字段2")%>’ /> wy#>Aq

if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) -,T!/E
{ ~:o$}`mW
e.Item.Attributes.Add("onclick","this.style.backgroundColor=’#99cc00’; kWVk^,
this.style.color=’buttontext’;this.style.cursor=’default’;"); w,vnpdT

8.关于日期格式 ?kQY ^pU
B5vLV@>]
日期格式设定 0XCAnMVo
DataFormatString="{0:yyyy-MM-dd}" @KU;'th
8IQ}%|lN
我觉得应该在itembound事件中 &*ocr &
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) Ky,upU
,f>9oOqqA
9.获取错误信息并到指定页面 `iM%R3&
9N)I\lcY
不要使用Response.Redirect,而应该使用Server.Transfer SO(BkxV@
kk6
!krZ
e.g [f6BA|
// in global.asax 0#eb] c
protected void Application_Error(Object sender, EventArgs e) { fxoEK}TM
if (Server.GetLastError() is HttpUnhandledException) Ys}^hy
Server.Transfer("MyErrorPage.aspx"); Y
z&!0Hfd
aK;OzB)
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) G$V=\60a-
} [r8[lkR
1.3dy]vG
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 D:bmq93PC

10.清空Cookie O!f37n-TB
Cookie.Expires=[DateTime]; }*QK;#NEc
Response.Cookies("UserName").Expires = 0 eS@j? Y0y

11.自定义异常处理 j,^&U|!
//自定义异常处理类 {cOx0=
