接收参数: D*+uH;ws
string a = Request.QueryString("id"); "@!z+x[8
string b = Request.QueryString("id1"); XHuY'\;-

2.为按钮添加对话框 j""I,$t
Button1.Attributes.Add("onclick","return confirm(’确认?’)"); )5Yv7x(K
button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") bX#IE[Yp}

3.删除表格选定记录 TQm x$
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; y3T-^
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() BcaMeb-Z

6.表格超连接列传递参数 p,}-8#K[

8.关于日期格式 .Tt \U
x3T)/'(
日期格式设定 ,eOOV@3C
DataFormatString="{0:yyyy-MM-dd}" >i~W$;t
`,H\j?
我觉得应该在itembound事件中 sLK J<=0i
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) Gm^@lWzG
EU]{S=T
9.获取错误信息并到指定页面 H,txbJ
w/KHS#~
不要使用Response.Redirect,而应该使用Server.Transfer /pgfa-<
GdEkA
e.g <ro0}%-z>M
// in global.asax qc~6F'?R
protected void Application_Error(Object sender, EventArgs e) { 8#'<SB
if (Server.GetLastError() is HttpUnhandledException) hXM8`iFW5
Server.Transfer("MyErrorPage.aspx"); -h^FSW($-R
Tn2Z{.q$
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) @gENv~m<OI
} q7mqzMDk
& S_gNa
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 ,kuJWaUC@
