1. 打开新的窗口并传送参数: HHcWyu

传送参数: Hm*?<o9mxC
response.write("<script>window.open(’*.aspx?id="+this.DropDownList1.SelectIndex+"&id1="+...+"’)</script>") O[O[E}8#
X4{O/G
接收参数: o1?bqVF;6
string a = Request.QueryString("id"); 2GC{+*
string b = Request.QueryString("id1"); 9qXKHro

2.为按钮添加对话框 2~(\d\k
Button1.Attributes.Add("onclick","return confirm(’确认?’)"); E[2>je
button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") $++SF)G1]_

3.删除表格选定记录 Os>^z@x
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; [)S&PK
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() MWZH-aA(.

6.表格超连接列传递参数 8K@>BFk1.
<asp:HyperLinkColumn Target="_blank" headertext="ID号" DataTextField="id" NavigateUrl="aaa.aspx?id=’ w8iXuRv
<%# DataBinder.Eval(Container.DataItem, "数据字段1")%>’ & name=’<%# DataBinder.Eval(Container.DataItem, "数据字段2")%>’ /> /*kc|V

7.表格点击改变颜色 jL]Y;T8
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) #Bo3:B8
{ !LAC_b
e.Item.Attributes.Add("onclick","this.style.backgroundColor=’#99cc00’; A-*y[/

8.关于日期格式 tB{HH%cV
)kk10AZV-E
日期格式设定 #w6ty<b;
DataFormatString="{0:yyyy-MM-dd}" qac8zt#2
C
{v>8Kp7_R
我觉得应该在itembound事件中 GJ Takhj3
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) P1qQ)-J

9.获取错误信息并到指定页面 J|=0 :G
5`\"UC7?%
不要使用Response.Redirect,而应该使用Server.Transfer L"Dos +
dKJ-{LV
e.g M'|?*aNK
// in global.asax !=bGU= ^
protected void Application_Error(Object sender, EventArgs e) { T-a[
if (Server.GetLastError() is HttpUnhandledException) XmAun
Server.Transfer("MyErrorPage.aspx"); h-+vNhH
?d' vIpzO!
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) >QSlH]M
} >1 %|T
twP%+/g]<
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 }Yargj_Gn
