2.为按钮添加对话框 Sa0\93oa

button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") @WmB0cc_

3.删除表格选定记录 jv ";?*I6.
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; `xSXGI
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() 0/Csc\Xl

4.删除表格记录警告 I

6.表格超连接列传递参数 *"#>Ov>

_uRgKoiy
日期格式设定 c<e$6:|xM
DataFormatString="{0:yyyy-MM-dd}" y"7?]#$9/
6rRPqO

我觉得应该在itembound事件中 bSmRo
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) ?vZ&CB

9.获取错误信息并到指定页面 0n1y$*I4
uy B
?-Y+
不要使用Response.Redirect,而应该使用Server.Transfer sI~{it#
HMBxj($eR
e.g VQX#P<
// in global.asax 6OVAsmE
protected void Application_Error(Object sender, EventArgs e) { $
@^n3ZQ4
if (Server.GetLastError() is HttpUnhandledException) QutQG
Server.Transfer("MyErrorPage.aspx"); PPohpdd)
n&@\[,B
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) u tQ_!3u
} s,0,w--=
e'u9 SpJ
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 TIS}'c'C
