1. 打开新的窗口并传送参数: yh=N@Z*zP

传送参数: K<J9~
response.write("<script>window.open(’*.aspx?id="+this.DropDownList1.SelectIndex+"&id1="+...+"’)</script>") :zR!/5

接收参数: T^q
0'#/
string a = Request.QueryString("id"); L:x-%m%w
string b = Request.QueryString("id1"); : E?V.
#A.@i+Zv
2.为按钮添加对话框 54qFfN8O

3.删除表格选定记录 XX~,>Q}H=

string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() wyG;8I

8.关于日期格式 .>nRzgo
8sCv]|cn
日期格式设定 sT' 5%4
DataFormatString="{0:yyyy-MM-dd}" ]0\MmAJRn
O| hpXkV
我觉得应该在itembound事件中 t()c=8qF|u
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) r"R#@V\'1b
ri.I pRe
9.获取错误信息并到指定页面 zv"Z DRW
Hq 188<
不要使用Response.Redirect,而应该使用Server.Transfer .GcKa024
j8`BdKg
e.g u~-8d;+?y
// in global.asax eR" <33{
protected void Application_Error(Object sender, EventArgs e) { BF <ikilR
if (Server.GetLastError() is HttpUnhandledException) Z(!\%mn
Server.Transfer("MyErrorPage.aspx"); !?gKqx'T$
2 Vrw
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) `~`k_7t.
} IaXeRq?<
fd2T=fz-
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 O7IJ%_A&
