1. 打开新的窗口并传送参数: SUW=-M

2.为按钮添加对话框 ~[~#PO
Button1.Attributes.Add("onclick","return confirm(’确认?’)"); Pv3G?u=4
button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") #\ysn|!J,

3.删除表格选定记录 c++q5bg@)

8.关于日期格式 ]k+(0qxG
'- #QK'p
日期格式设定 G-sQL'L[U
DataFormatString="{0:yyyy-MM-dd}" %mzDmrzq
NGO?K?
我觉得应该在itembound事件中 8qxZ7|Y@
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) XJ" xMv
%P(2uesd
9.获取错误信息并到指定页面 Py/~Q-8p
8=?U7aw
不要使用Response.Redirect,而应该使用Server.Transfer "I{Lcn~!@
ltNY8xrdGN
e.g nY\X!K65
// in global.asax yF+mJ >kj
protected void Application_Error(Object sender, EventArgs e) { >!tfvM2X{
if (Server.GetLastError() is HttpUnhandledException) kV!1k<f
Server.Transfer("MyErrorPage.aspx"); 0I2?fz)
4p6T0II_$
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) M&H,`gm
} ocp
BJ
fBYH,M
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 5D
