3.删除表格选定记录 :~-i&KNk

string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() 2f{kBD

8.关于日期格式 xL|?(pQ/BK
Mi<*6j0
日期格式设定 i4 P$wlO
DataFormatString="{0:yyyy-MM-dd}" *P&OxVz
y+l<vJu
我觉得应该在itembound事件中 J&(
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) ER/\ +Z#Z

9.获取错误信息并到指定页面 XL=2wh
hcj{%^p
不要使用Response.Redirect,而应该使用Server.Transfer {E3;r7
}`#j;H$i
e.g ='KPT1dW*
// in global.asax bn5"dxV
protected void Application_Error(Object sender, EventArgs e) { 9tW3!O^_
if (Server.GetLastError() is HttpUnhandledException) (69kvA&|q
Server.Transfer("MyErrorPage.aspx"); O2/%mFS.
H 3W_}f
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) x/pC%25
} gX/|aG$a!U
[''=><
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 y>?k<
