1. 打开新的窗口并传送参数: d R]Q$CJ

2.为按钮添加对话框 1[t=XDz/e
Button1.Attributes.Add("onclick","return confirm(’确认?’)"); pmFk50`
button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") +ke1Cn'[

3.删除表格选定记录 =pznu+,
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; pKjoi{
Z
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() a
/:@"&Y

6.表格超连接列传递参数 #~Q8M*~@

this.style.color=’buttontext’;this.style.cursor=’default’;"); FXo2Y]K3`L

8.关于日期格式 |
W#~F&{]
9e<Zgr?N
日期格式设定 m%QqmTH
DataFormatString="{0:yyyy-MM-dd}" )Mzt3u
d^39t4
我觉得应该在itembound事件中 ]Qi,j#X
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) =:h3w#_c
R V!o4"\]
9.获取错误信息并到指定页面 Z{{t^+XG
`HUf v@5
不要使用Response.Redirect,而应该使用Server.Transfer {U
<tc4^
J"[3~&em
e.g 015Owi
// in global.asax 'o\;x"YJ
protected void Application_Error(Object sender, EventArgs e) { 2/tb6' =
if (Server.GetLastError() is HttpUnhandledException) qmmv7==
Server.Transfer("MyErrorPage.aspx"); F(CRq`
$cK^23H/Fj
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) '7nJb6V,0l
} wL<j:>Ke[3
6MrKi|'X@
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 J0Four#MD
