3.删除表格选定记录 r!N]$lB
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; w-N1.^
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() @LD6:gy

6.表格超连接列传递参数 99ASIC!

8.关于日期格式 O3_B<Em
co]Gmg6p
日期格式设定 Va9q`XbyO
DataFormatString="{0:yyyy-MM-dd}" V<0$xV1b|=
d(l|hmj4j9
我觉得应该在itembound事件中 ofwQ:0@
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) qC
j*>D
ep?:;98|t
9.获取错误信息并到指定页面 0$Ff#8

不要使用Response.Redirect,而应该使用Server.Transfer |zMqJ.qu
jU$Y>S>l
e.g m "]!I~jd
// in global.asax zzf7S%1I
protected void Application_Error(Object sender, EventArgs e) { swZpWC
if (Server.GetLastError() is HttpUnhandledException) 5#u.pu
Server.Transfer("MyErrorPage.aspx"); 3X'WR]
eY3=|RR
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) |!b9b(_j9
} {})y^L

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 UX}*X`{
