e gdbv
传送参数: ~`c(7
response.write("<script>window.open(’*.aspx?id="+this.DropDownList1.SelectIndex+"&id1="+...+"’)</script>") (\$=de>?
b9RJ>K
接收参数: +Z=%4
string a = Request.QueryString("id"); "J"RH:$v
string b = Request.QueryString("id1"); H9%[!

2.为按钮添加对话框 P1qQ)-J
Button1.Attributes.Add("onclick","return confirm(’确认?’)"); f[fH1cu&`
button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") Kv~'*A)d

3.删除表格选定记录 ;>*Pwz`~jT
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; ,Z$!:U
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() Y5z5LG4

7.表格点击改变颜色 U;#G$
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) ($Q|9>5,

e.Item.Attributes.Add("onclick","this.style.backgroundColor=’#99cc00’; HdRwDW@7=
this.style.color=’buttontext’;this.style.cursor=’default’;"); #xh

写在DataGrid的_ItemDataBound里 Uc9hv?

e.Item.Attributes.Add("onmouseover","this.style.backgroundColor=’#99cc00’; 8&SWQ

8.关于日期格式 S5\KI+;PW
rP IAu[],g
日期格式设定 Kf# iF*
DataFormatString="{0:yyyy-MM-dd}" xy-Vw"I[bh
U#`2~Qv/1
我觉得应该在itembound事件中 y
~Fi
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) JC#5CCz

9.获取错误信息并到指定页面 lE$(*1H
[IgqK5@
不要使用Response.Redirect,而应该使用Server.Transfer wW7# M
e4FR)d0x
e.g p\Fxt1Y@X
// in global.asax 3Xm>
3
protected void Application_Error(Object sender, EventArgs e) { a5 pXn v]A
if (Server.GetLastError() is HttpUnhandledException) gOr%N!5
Server.Transfer("MyErrorPage.aspx"); [Pl''[
<vt}+uMzXv
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) xy4P_
} 0xH&^Ia1B
~9#'s'
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 q4g)/x%nc
