1. 打开新的窗口并传送参数: u:4["ViC
k&DGJ5m$.
传送参数: Iu6W=A
response.write("<script>window.open(’*.aspx?id="+this.DropDownList1.SelectIndex+"&id1="+...+"’)</script>") :_c*m@=z(
:J%'=_I&H
接收参数: p+D=}O
string a = Request.QueryString("id"); OWV/kz5'H
string b = Request.QueryString("id1"); Dm4B
}vsO^4Sjc
2.为按钮添加对话框 1#!@["
Button1.Attributes.Add("onclick","return confirm(’确认?’)"); o_:Qk;t
button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") e-!?[Ujv*%

3.删除表格选定记录 ,Qo}J@e(
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; $F1_^A[
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() C*j9Iaj

L.SDM z
日期格式设定 ny278tr Q7
DataFormatString="{0:yyyy-MM-dd}" D_O 5k|-V

我觉得应该在itembound事件中 -$AjD?;
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) .Ql;(Wyl
bq c;.4$
9.获取错误信息并到指定页面 6>@(/mh*
H%*~l
不要使用Response.Redirect,而应该使用Server.Transfer X4Pm)N`
9c"0~7v
e.g ;6DR.2}?>
// in global.asax 2Som0T<2
protected void Application_Error(Object sender, EventArgs e) { 6&g!ZE'G
if (Server.GetLastError() is HttpUnhandledException) e7Yb=/F
Server.Transfer("MyErrorPage.aspx"); 1h#w"4
&@mvw=d
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) )v*v
} .a 'ETNY:>
bl(BA}<
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 $ka1X&f
