1. 打开新的窗口并传送参数: frN3S
zoP%u,XL
传送参数: Y-p<qL|_
response.write("<script>window.open(’*.aspx?id="+this.DropDownList1.SelectIndex+"&id1="+...+"’)</script>") F98i*K`"
1pP1d%
接收参数: >qR~'$,$
string a = Request.QueryString("id"); rg5]&<Vq8
string b = Request.QueryString("id1"); j'GtgT
j7
d:v7+_
2.为按钮添加对话框 R8&|+ya
Button1.Attributes.Add("onclick","return confirm(’确认?’)"); <y)E>Fl
button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") phP>3f.T

3.删除表格选定记录 f vLC_'M
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; +a|/l
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() #Qbl=o4
'#Dg8/r!
4.删除表格记录警告 {J]-<:XD

5.点击表格行链接另一页 Z$'IBv
private void grdCustomer_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e) ]gEhE
{ $-vo}k%M
//点击表格打开 )1F<6R
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem) 'C?NJ~MN
e.Item.Attributes.Add("onclick","window.open(’Default.aspx?id=" + e.Item.Cells[0].Text + "’);"); Qw)9r{f

} IA*KaX2S<

★特别注意:【?id=】 处不能为 【?id =】 K7`YJp`i
6.表格超连接列传递参数 TGV
<asp:HyperLinkColumn Target="_blank" headertext="ID号" DataTextField="id" NavigateUrl="aaa.aspx?id=’ S~F`
<%# DataBinder.Eval(Container.DataItem, "数据字段1")%>’ & name=’<%# DataBinder.Eval(Container.DataItem, "数据字段2")%>’ /> 7#-y-B]l

7.表格点击改变颜色 .FP$ IWt/1
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) 5/I_w0
{ 7#2j>G{?]v
e.Item.Attributes.Add("onclick","this.style.backgroundColor=’#99cc00’; >nnY:7m
this.style.color=’buttontext’;this.style.cursor=’default’;"); {0yu
}
Xm_$

BWUq%o,@g
写在DataGrid的_ItemDataBound里 G '#41>q+
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) vR hnX
{ Hs?zq
e.Item.Attributes.Add("onmouseover","this.style.backgroundColor=’#99cc00’; ~OFvu}]
this.style.color=’buttontext’;this.style.cursor=’default’;"); G<qIY&D'
e.Item.Attributes.Add("onmouseout","this.style.backgroundColor=’’;this.style.color=’’;"); 6s xz_f

8.关于日期格式 <GIwRVCU
``QHG&$/
日期格式设定 83iCL; GS=
DataFormatString="{0:yyyy-MM-dd}" 0SV \{]2
`
2%6V)s
我觉得应该在itembound事件中 3]LN;s]ac
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) JW+*d`8Z[
($!KzxF3
9.获取错误信息并到指定页面 rVryt<2:@r
ZX.TqvK/r
不要使用Response.Redirect,而应该使用Server.Transfer D`o<,Y
3y`F<&sA
e.g f7<pEGb
// in global.asax FGanxv@15
protected void Application_Error(Object sender, EventArgs e) { 3h=8"lRc
if (Server.GetLastError() is HttpUnhandledException) "pvZ,l>8f
Server.Transfer("MyErrorPage.aspx"); z,Lzgh
WeT* C
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) M}F~_S0h
} f_6`tq m%
Nhf~PO({&
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 wNQqfqZ

10.清空Cookie hR)2xz
Cookie.Expires=[DateTime]; -- k:a$Nt
Response.Cookies("UserName").Expires = 0 `T WN^0!]
