1. 打开新的窗口并传送参数: QJ(%rvn3

传送参数: d[,Rgdd@I
response.write("<script>window.open(’*.aspx?id="+this.DropDownList1.SelectIndex+"&id1="+...+"’)</script>") Sv /P:r

接收参数: I@6+AU~,6
string a = Request.QueryString("id"); ZwLr>?0$
p
string b = Request.QueryString("id1"); ?rQ .nN

2.为按钮添加对话框 ,m?V3xvq
Button1.Attributes.Add("onclick","return confirm(’确认?’)"); s.Z{mnD6
button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") xCXsyZ2h
tyW}=xs
3.删除表格选定记录 uuwJ-
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; c(
U,FUS
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() !"qT2<A

4.删除表格记录警告 R3_OCM_*

5.点击表格行链接另一页 "zY~*3d
private void grdCustomer_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e) (BP p2^
{ $zCCeRP
//点击表格打开 W7uX

6.表格超连接列传递参数 H}~K51
<asp:HyperLinkColumn Target="_blank" headertext="ID号" DataTextField="id" NavigateUrl="aaa.aspx?id=’ *Oy*
\cX2[
<%# DataBinder.Eval(Container.DataItem, "数据字段1")%>’ & name=’<%# DataBinder.Eval(Container.DataItem, "数据字段2")%>’ /> 0;><@{'

7.表格点击改变颜色 `mteU"{bx
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) +ho=0>
{ Mo N/?VA
e.Item.Attributes.Add("onclick","this.style.backgroundColor=’#99cc00’; W3!-;l
this.style.color=’buttontext’;this.style.cursor=’default’;"); )cizd^{
} na
$MR3@e

{ H*k\C
e.Item.Attributes.Add("onmouseover","this.style.backgroundColor=’#99cc00’; KH?6O%d

8.关于日期格式 `=hCS0F
meV Z_f/
日期格式设定 <B|b'XVH2
DataFormatString="{0:yyyy-MM-dd}" $Q#n'#c
PQlA(v+S
我觉得应该在itembound事件中 Tf5m
YCk
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) 4Us,DS_/

9.获取错误信息并到指定页面 :l]qTCmY
&1T)'Bn
不要使用Response.Redirect,而应该使用Server.Transfer 3xz~##
?Ybq]J\q
e.g RYvcuA)
// in global.asax "ADI.
protected void Application_Error(Object sender, EventArgs e) {
YC6guy>
if (Server.GetLastError() is HttpUnhandledException) x#SE%j?
Server.Transfer("MyErrorPage.aspx"); d.w]\
6BA$v-VVU
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) ?`xF>P]M
} N,XjZ26
t{},Th
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 M}X `
