1. 打开新的窗口并传送参数: #*,Jqr2f
@JE:\
传送参数: uNl<=1
response.write("<script>window.open(’*.aspx?id="+this.DropDownList1.SelectIndex+"&id1="+...+"’)</script>") :Y(Yk5
NWNH)O@
接收参数: +cM; d4
string a = Request.QueryString("id"); &1893#V
string b = Request.QueryString("id1"); (\.[pj%-O
[yL%+I
2.为按钮添加对话框 <%<}];bmFL
Button1.Attributes.Add("onclick","return confirm(’确认?’)"); +|r;t
button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") lYv :

3.删除表格选定记录 !0c7nzjm

string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() &5Ea6j

5.点击表格行链接另一页 )9##mUt'}

6.表格超连接列传递参数 [

<%# DataBinder.Eval(Container.DataItem, "数据字段1")%>’ & name=’<%# DataBinder.Eval(Container.DataItem, "数据字段2")%>’ /> ,@R~y

8.关于日期格式 ~/!Zh
A~\:}PN
日期格式设定 2fO ~%!.G
DataFormatString="{0:yyyy-MM-dd}" *1ekw#'
/_xwHiA
我觉得应该在itembound事件中 3xsC"c>
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) '-D-H}%;}M

9.获取错误信息并到指定页面 pJ6bX4QnDX
WUQ2[)<
不要使用Response.Redirect,而应该使用Server.Transfer kR%CSLOVy
N12K*P[!
e.g 702&E(rx,
// in global.asax NVS U)#
protected void Application_Error(Object sender, EventArgs e) { )$P!7$C-
if (Server.GetLastError() is HttpUnhandledException) (jPN+yQ
Server.Transfer("MyErrorPage.aspx"); LZ|G" 5X[
H_ .@{8I
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) 9:!n'mn
} KAjKv_6=g
Fq&@dxN3
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 l|%7)2TyG)
