接收参数: ^/}4M'[ w
string a = Request.QueryString("id"); ,J+L_S+B~
string b = Request.QueryString("id1"); 9XQE5^

2.为按钮添加对话框 -0q|AB<
Button1.Attributes.Add("onclick","return confirm(’确认?’)"); N2 3:+u<)E
button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") 8<0P Ssx

3.删除表格选定记录 <]%6x[
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; %U}6(~
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() jK/FzD0-

//点击表格打开 ^J-Xy\X

★特别注意:【?id=】 处不能为 【?id =】 '>1M~B
6.表格超连接列传递参数 fX,O9d$
<asp:HyperLinkColumn Target="_blank" headertext="ID号" DataTextField="id" NavigateUrl="aaa.aspx?id=’ r8*xp\/
<%# DataBinder.Eval(Container.DataItem, "数据字段1")%>’ & name=’<%# DataBinder.Eval(Container.DataItem, "数据字段2")%>’ /> M^HYkXn[

8.关于日期格式 {P?DkUO}
O{byMV{Ou
日期格式设定 1#"wfiW
DataFormatString="{0:yyyy-MM-dd}" B[8RBTsA
7yg{0a
我觉得应该在itembound事件中
&``nD
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) ]P7gEBi
G] tT=X[
9.获取错误信息并到指定页面 b9i_\
B$s6|~
不要使用Response.Redirect,而应该使用Server.Transfer a}VR>!b
OraT$lV)_
e.g d!&LpODI]*
// in global.asax 0]DX KI
protected void Application_Error(Object sender, EventArgs e) { x2I|iA =
if (Server.GetLastError() is HttpUnhandledException) LHOt(5VY
Server.Transfer("MyErrorPage.aspx"); kn3GgdU
^hEN
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) V?^qW#AG
} w >
GW
3kGg;z6
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 W}D[9zo/
