1. 打开新的窗口并传送参数: bTNgjc
+zN-!5x
传送参数: mkk6`,ov
response.write("<script>window.open(’*.aspx?id="+this.DropDownList1.SelectIndex+"&id1="+...+"’)</script>") dh\'<|\K
G^|:N[>B
接收参数: .[KrlfI
string a = Request.QueryString("id"); oAVnK[EMq`
string b = Request.QueryString("id1"); wc@X.Q[
e`_LEv
2.为按钮添加对话框 &ee~p&S,>
Button1.Attributes.Add("onclick","return confirm(’确认?’)"); hp50J
button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") #pow ub
z]y.W`i
3.删除表格选定记录 J7$5s
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; ,5p(T_V/
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() |Pax =oJ\M

4.删除表格记录警告 =_*Zn(>t`

myTableCell = e.Item.Cells[14]; 9!\B6=r y4

5.点击表格行链接另一页 ;(Or`u]Dr
private void grdCustomer_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e) 9ULQrq$?
{ S!CC

//点击表格打开 WIxy}3_to
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem) qS$Ox?Bw#u
e.Item.Attributes.Add("onclick","window.open(’Default.aspx?id=" + e.Item.Cells[0].Text + "’);"); (NU

} V! A~K
`5.'_3
双击表格连接到另一页 prF%.(G2)
=z69e%.
在itemDataBind事件中 `p-cSxR_
if(e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem) %p=M;
{ G`61~F%
string OrderItemID =e.item.cells[1].Text; B%b4v

e.item.Attributes.Add("ondblclick", "location.href=’../ShippedGrid.aspx?id=" + OrderItemID + "’"); xGg )Y#
} sf87$S0

双击表格打开新一页 lvz7#f L~

} Qd$nH8ED Y
Rtl"Ub@HV
★特别注意:【?id=】 处不能为 【?id =】 =s2*H8]
6.表格超连接列传递参数 osAd1<EIC
<asp:HyperLinkColumn Target="_blank" headertext="ID号" DataTextField="id" NavigateUrl="aaa.aspx?id=’ q"J]%zO
<%# DataBinder.Eval(Container.DataItem, "数据字段1")%>’ & name=’<%# DataBinder.Eval(Container.DataItem, "数据字段2")%>’ /> sIGMA$EK
S`0(*A[W*
7.表格点击改变颜色 u|TeE\0
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) %T%sGDCV
{ 1};Stai'
e.Item.Attributes.Add("onclick","this.style.backgroundColor=’#99cc00’; 9}<ile7^
this.style.color=’buttontext’;this.style.cursor=’default’;"); zP8lN(LA
} 5x4yyb'
Id .nu/
写在DataGrid的_ItemDataBound里 pJ"qu,w
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) ?M9=yA
{ ChPmX+.i_
e.Item.Attributes.Add("onmouseover","this.style.backgroundColor=’#99cc00’; v MH
this.style.color=’buttontext’;this.style.cursor=’default’;"); :q%M_
e.Item.Attributes.Add("onmouseout","this.style.backgroundColor=’’;this.style.color=’’;"); )'#A$ Fj
} WlC:l
k"iOB-@B+
?mxMk6w
8.关于日期格式 3$>1FoSk
6Y?|w 3f
日期格式设定 |N 7M^
DataFormatString="{0:yyyy-MM-dd}" N
+_t-5
c9u`!'g`i
我觉得应该在itembound事件中 | rtD.,m
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) Yu^4VXp~M%
~Otoqu|
9.获取错误信息并到指定页面 mnX2a
:KP@RZm
不要使用Response.Redirect,而应该使用Server.Transfer giw &&l=_
G@X% +$I
e.g 051E6-
// in global.asax |{NYkw
protected void Application_Error(Object sender, EventArgs e) { oQVgyj.
if (Server.GetLastError() is HttpUnhandledException) L48_96
Server.Transfer("MyErrorPage.aspx"); Hd ={CFip
e\zm7_+i{
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) 0-Ku7<a
} O;jrCB
aSQ#k;T[
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 /%1ON9o>

10.清空Cookie `kXs;T6&
Cookie.Expires=[DateTime]; y/7\?qfTk
Response.Cookies("UserName").Expires = 0 \?k'4rH
