1. 打开新的窗口并传送参数: U( W#H|

传送参数: QlJCdCSy
response.write("<script>window.open(’*.aspx?id="+this.DropDownList1.SelectIndex+"&id1="+...+"’)</script>") t1Hd-]28V
q5lRc=.b[
接收参数: Cd7jG
string a = Request.QueryString("id"); wIxLr{
string b = Request.QueryString("id1"); K_]LK
rM [Ps=5
2.为按钮添加对话框 *Ei~2O}
Button1.Attributes.Add("onclick","return confirm(’确认?’)"); XZd !c Ff
button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") F!pUfF,&

3.删除表格选定记录 WHbvb3'
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; ?aSL'GI
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() Lrq+0dI 65

★特别注意:【?id=】 处不能为 【?id =】 /x$ jd)C
6.表格超连接列传递参数 <6(u%t0k5
<asp:HyperLinkColumn Target="_blank" headertext="ID号" DataTextField="id" NavigateUrl="aaa.aspx?id=’ r\Man'h$
<%# DataBinder.Eval(Container.DataItem, "数据字段1")%>’ & name=’<%# DataBinder.Eval(Container.DataItem, "数据字段2")%>’ /> 7F+f6(hB

7.表格点击改变颜色 $#t&W&
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) z2"2Xqy<U
{ ]j1BEO!Bg
e.Item.Attributes.Add("onclick","this.style.backgroundColor=’#99cc00’; &p=~=&g=

写在DataGrid的_ItemDataBound里 uX.Aq@j

8.关于日期格式 60`y= !?f
Ma{|+\Q.Z
日期格式设定 t`F%$q
DataFormatString="{0:yyyy-MM-dd}" DK4V/>@8
N18Zsdrp
我觉得应该在itembound事件中 &3u*
zV$
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) Yt|{l
v{%2`_c
9.获取错误信息并到指定页面 _Z8zD[l
F}sfk}rp
不要使用Response.Redirect,而应该使用Server.Transfer E"u>&uPH
J+z0,N[
e.g snj+-'4T
// in global.asax \J1Jn~
protected void Application_Error(Object sender, EventArgs e) { +j`*?pPD(.
if (Server.GetLastError() is HttpUnhandledException) h V=)T^Q
Server.Transfer("MyErrorPage.aspx"); I}?fy\1A&
T[<9Ty'^
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) a<vCAFQ
} 3!*J;Y
rJ<v1Yb
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 )9@Ftzg|

10.清空Cookie bNc=}^
Cookie.Expires=[DateTime]; a&y%|Gs^f
Response.Cookies("UserName").Expires = 0 6oJ~Jdn'
