string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() gFaZ ._

<%# DataBinder.Eval(Container.DataItem, "数据字段1")%>’ & name=’<%# DataBinder.Eval(Container.DataItem, "数据字段2")%>’ /> ,!>

8.关于日期格式 huqtk4u
NioqJG?p
日期格式设定 ]DnAW'm
DataFormatString="{0:yyyy-MM-dd}" ?[#w*Am7
cPcH
8Vd
我觉得应该在itembound事件中 {n>.Y-=
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) RV]#Bg*[#
bF9.k
9.获取错误信息并到指定页面 .?:#<=1
+8<$vzB
不要使用Response.Redirect,而应该使用Server.Transfer #;99vwc
e
oE)Mq
e.g DD/B\
// in global.asax ~$//4kES
protected void Application_Error(Object sender, EventArgs e) { {md5G$*%
if (Server.GetLastError() is HttpUnhandledException) uK#2vgT
Server.Transfer("MyErrorPage.aspx"); X$~T*l0
.h/2-pQ>
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) K:VZ#U(_
} 9D,!]
WuI$
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 *)?'!
