1. 打开新的窗口并传送参数: )yK!EK\

接收参数: 7W>T=

string a = Request.QueryString("id"); c>^_4QQ
string b = Request.QueryString("id1"); \/5 8#

2.为按钮添加对话框 1

Button1.Attributes.Add("onclick","return confirm(’确认?’)"); c"|^Lo.
button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") 8-m"] o3

3.删除表格选定记录 f(3#5288
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; v\<`"
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() b w cPY

5.点击表格行链接另一页 04,]upC${W
private void grdCustomer_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e) Hiw{1E:rW

//点击表格打开 y<5s)OehG
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem) /at#[Pw~01

6.表格超连接列传递参数 #K

<asp:HyperLinkColumn Target="_blank" headertext="ID号" DataTextField="id" NavigateUrl="aaa.aspx?id=’ k~:B3p
<%# DataBinder.Eval(Container.DataItem, "数据字段1")%>’ & name=’<%# DataBinder.Eval(Container.DataItem, "数据字段2")%>’ /> uGgR@+7?Z

7.表格点击改变颜色 y_\vXY'
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) 0gxbo
{ VNaa(Q
e.Item.Attributes.Add("onclick","this.style.backgroundColor=’#99cc00’; 27gK
Y
Zf;
this.style.color=’buttontext’;this.style.cursor=’default’;"); bp;)*
} nIXq2TzJ
Nqy',N
写在DataGrid的_ItemDataBound里 z[V|W
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) (5VP*67
{ m
&s0Ub
e.Item.Attributes.Add("onmouseover","this.style.backgroundColor=’#99cc00’; NNS n]LP
this.style.color=’buttontext’;this.style.cursor=’default’;"); f |aO9w
e.Item.Attributes.Add("onmouseout","this.style.backgroundColor=’’;this.style.color=’’;"); ]w! x

8.关于日期格式 #;>J<>
Cd]d[{NJ;
日期格式设定 Spt[b.4m F
DataFormatString="{0:yyyy-MM-dd}" zN*/G6>A
eRv3qK{`
我觉得应该在itembound事件中 Yw4c`MyL
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) M'Q{2%:>a
-N~*h
9.获取错误信息并到指定页面 }yC ve
(\>_{"*=
不要使用Response.Redirect,而应该使用Server.Transfer 2r<UYB
@D Qg1|m
e.g vD^^0-Pk6
// in global.asax
VTy!<I
protected void Application_Error(Object sender, EventArgs e) { >J|I
if (Server.GetLastError() is HttpUnhandledException) |s[m;Qm[ku
Server.Transfer("MyErrorPage.aspx"); zH}u9IR3`
Ds$FO}KD{
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) tbl!{Qwx
} p;U[cGHC
C.FGi`rrm
Redirect会导致post-back的产生从而丢失了错误信息,所以页面导向应该直接在服务器端执行,这样就可以在错误处理页面得到出错信息并进行相应的处理 `N;u#z
;9/6X#;$
10.清空Cookie O=G2bdY{,
Cookie.Expires=[DateTime]; S\MD]>4
Response.Cookies("UserName").Expires = 0 Yk6fr~b

11.自定义异常处理 SG$/v
