1. 打开新的窗口并传送参数: ZP?k |sEH
}Iub{30mp
传送参数: 1L'[DKb'
response.write("<script>window.open(’*.aspx?id="+this.DropDownList1.SelectIndex+"&id1="+...+"’)</script>") ?w#
>Cs(
I(Nsm3L
接收参数: XrC{{K
string a = Request.QueryString("id"); {R8Q`2R
string b = Request.QueryString("id1"); [RD ^@~x
!gy'_Y
2.为按钮添加对话框 Hi|2z5=V
Button1.Attributes.Add("onclick","return confirm(’确认?’)"); <-Q0WP_^
button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") +,>f-kaV
.Z&OKWL
3.删除表格选定记录 5HG 7M&_
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; .mDqZOpf=4
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() o;Zoj}
p"H8;fPA0
4.删除表格记录警告 0P/A

5.点击表格行链接另一页 Ynz^M{9)K
private void grdCustomer_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e) 10#!{].#x
{ Y1k/ngH
//点击表格打开 {]<D"x;
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem) GJO/']k
e.Item.Attributes.Add("onclick","window.open(’Default.aspx?id=" + e.Item.Cells[0].Text + "’);"); 8.pz?{**T
} 3jS=
<Dm6CH
双击表格连接到另一页 + {hxEDz
y^@%Xrs
在itemDataBind事件中 5.?O PK6
if(e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem) Y ga}8DU

string OrderItemID =e.item.cells[1].Text; o95O!5 hl

e.item.Attributes.Add("ondblclick", "location.href=’../ShippedGrid.aspx?id=" + OrderItemID + "’"); a+{g~/z;,Q

双击表格打开新一页 {Y/|7Cl0

string OrderItemID =e.item.cells[1].Text; qh7o;x~,

e.item.Attributes.Add("ondblclick", "open(’../ShippedGrid.aspx?id=" + OrderItemID + "’)"); ''5%5(Y.r
} nrt0[E-&~
l42m81x"
★特别注意:【?id=】 处不能为 【?id =】 yFpHRfF}
6.表格超连接列传递参数 w|L~+
<asp:HyperLinkColumn Target="_blank" headertext="ID号" DataTextField="id" NavigateUrl="aaa.aspx?id=’ /#:RYM'Tu
<%# DataBinder.Eval(Container.DataItem, "数据字段1")%>’ & name=’<%# DataBinder.Eval(Container.DataItem, "数据字段2")%>’ /> ?G?=,tV
2M&4]d
7.表格点击改变颜色 i[\[xfk
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) gE
,j\M*
{ WN?T*bz2
e.Item.Attributes.Add("onclick","this.style.backgroundColor=’#99cc00’; fwq|8^S@
this.style.color=’buttontext’;this.style.cursor=’default’;"); ^mJvB[ u|
} e< CPaun

e.Item.Attributes.Add("onmouseover","this.style.backgroundColor=’#99cc00’; dX$])b_Uw

e.Item.Attributes.Add("onmouseout","this.style.backgroundColor=’’;this.style.color=’’;"); /vPb
} Iyc')\W&
!8L

8.关于日期格式 XS!ZTb>[
6pLwwZD
日期格式设定 :mJM=FeJ
DataFormatString="{0:yyyy-MM-dd}" $U8ap4EXM
j2P|cBXu
我觉得应该在itembound事件中 +%<Jr<~W
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) ;9I#>u
v
PGuEfz
9.获取错误信息并到指定页面 K[kmfXKu
OeAPBhTmFj
不要使用Response.Redirect,而应该使用Server.Transfer z9+94<J
D/:)rj14b
e.g }cPV_^{
// in global.asax {``}TsN
protected void Application_Error(Object sender, EventArgs e) { ?+|tPjg$
if (Server.GetLastError() is HttpUnhandledException) Bjo&
Server.Transfer("MyErrorPage.aspx"); 6)3eB{$;
b?Jm)
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) -$0S#/)Z
} (mD]}{>
SW; bE
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 xw-q)u

10.清空Cookie ua[\npz5
Cookie.Expires=[DateTime]; V8sY7QK=
Response.Cookies("UserName").Expires = 0 q@sH@-z4]
