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

3.删除表格选定记录 }V93~>
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; [:/7OM
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() 2-

8.关于日期格式 vpr@
OuJy$e
日期格式设定 "%@=?X8
DataFormatString="{0:yyyy-MM-dd}" GlkAJe]
RBp(dKxM$w
我觉得应该在itembound事件中 -<HvhW
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) QH?2v

9.获取错误信息并到指定页面 W*WH .1&
JqV<A3i
不要使用Response.Redirect,而应该使用Server.Transfer J*4_|j;Z-E
\crb&EgID
e.g JbD)}(G;
// in global.asax Vm%ux>}
protected void Application_Error(Object sender, EventArgs e) { sOtNd({
if (Server.GetLastError() is HttpUnhandledException) 6W#F Ss~
Server.Transfer("MyErrorPage.aspx"); tFP;CW!E
|$*9j""u
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) /JY ph^3][
} ^eT>R,aB
,Z\,IRn
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 \?]HqPibx
