1. 打开新的窗口并传送参数: @!z$Sp=

接收参数: nuf@}W>y
string a = Request.QueryString("id"); Q `e~MD
string b = Request.QueryString("id1"); >:w?qEaE

2.为按钮添加对话框 tyc8{t#Z

button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") b\SXZN)Be

3.删除表格选定记录 6V'wQqJ
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; QRsqPh&-
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() ;Ri 3#*a=

8.关于日期格式 8Bj4_!g
HC?0Lj
日期格式设定 P= e4lF.
DataFormatString="{0:yyyy-MM-dd}" 'c#IMlv
,E%1Uq"
我觉得应该在itembound事件中 9e]'OKL+
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) o\&~CW~@~
`(3SfQ-
9.获取错误信息并到指定页面 ooY\t +
=PV/`I_h
不要使用Response.Redirect,而应该使用Server.Transfer wcwQj Hwd
~eHRlXL'
e.g juH wHt
// in global.asax FtN}]@F
protected void Application_Error(Object sender, EventArgs e) { F#B5sLNb
if (Server.GetLastError() is HttpUnhandledException) 6eM6[
Server.Transfer("MyErrorPage.aspx"); #^Ys{
^/k,
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) z9 O~W5-U
}
O)O Uy
21ViHV
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 7 %3<~'v[
