1. 打开新的窗口并传送参数: ?O.6 r"

接收参数: yw3U"/yw
string a = Request.QueryString("id"); tUAY]BJ*s
string b = Request.QueryString("id1"); T0np<l]A
w'!}(Z5X?
2.为按钮添加对话框 [r~rIb%Zj
Button1.Attributes.Add("onclick","return confirm(’确认?’)"); NkjQyMF
button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") No92Y^~/

3.删除表格选定记录 {7M4SC@p|
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; )*$
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() :;hBq4h

8.关于日期格式 $G([#N<
gmH0-W)=
日期格式设定 HE.Dl7{
DataFormatString="{0:yyyy-MM-dd}" p.7p,CyB

我觉得应该在itembound事件中

e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) g<jK^\eW

9.获取错误信息并到指定页面 4'eVFu+62

不要使用Response.Redirect,而应该使用Server.Transfer k5\
zGsol
Iz=E8R g
e.g B'~i Z65
// in global.asax :z5Ibas:
protected void Application_Error(Object sender, EventArgs e) { =:}DD0o*
if (Server.GetLastError() is HttpUnhandledException) 97
X60<
Server.Transfer("MyErrorPage.aspx"); CZno2$8@e

//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) %[F;TZt

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 |"&4"nwa
