1. 打开新的窗口并传送参数: Y34/+Fi

传送参数: W+Xz$j/u
response.write("<script>window.open(’*.aspx?id="+this.DropDownList1.SelectIndex+"&id1="+...+"’)</script>") `:eU.
-&|:0#@P
接收参数: {`(>O"_[Q
string a = Request.QueryString("id"); {o0qUX>[
string b = Request.QueryString("id1"); ^Dg<Ki

2.为按钮添加对话框 UDy(dn>J:J
Button1.Attributes.Add("onclick","return confirm(’确认?’)"); W3r?7!~
button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") uI~s8{0T6
)[L^Dmd,
3.删除表格选定记录 0fm*`4Q
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; gn8|/ev
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() hoM|P8
}rh

6.表格超连接列传递参数 {\H/y c|@

8.关于日期格式 7tUA>;++
'* mH*?Y
日期格式设定 &Z(K6U#.
DataFormatString="{0:yyyy-MM-dd}" **9x?s
F+R?a+e
我觉得应该在itembound事件中 kiUGZ^k\s
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) :B3[:MpL}
j',W 64
9.获取错误信息并到指定页面 k@zy
*eI)Z=8
不要使用Response.Redirect,而应该使用Server.Transfer [Wd-Zn%
XO#/Fv!
e.g rX_@Ihv'
// in global.asax X%z }VA
protected void Application_Error(Object sender, EventArgs e) { valtev0<
if (Server.GetLastError() is HttpUnhandledException) L,y6^J!
Server.Transfer("MyErrorPage.aspx"); 8n1'x;
!cKz7?w
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) B9p?8.[
} rpeJkG@+
7Q\|=$2
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 mc=LP>uoS
