string a = Request.QueryString("id"); a!6OE"?QQ
string b = Request.QueryString("id1"); iz|9a|k6x

2.为按钮添加对话框 eB1eUK>

button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") rq|czQ

3.删除表格选定记录 ysP/@;jC
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; MrygEC 5
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() 5'}!v

4.删除表格记录警告 \=:g$_l

5.点击表格行链接另一页 7JK 'vT
private void grdCustomer_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e) !c;p4B)
{ {>qrf:
//点击表格打开 K^p"Z$$

6.表格超连接列传递参数 5_T>HHR6
<asp:HyperLinkColumn Target="_blank" headertext="ID号" DataTextField="id" NavigateUrl="aaa.aspx?id=’ 2/NWWoKw
<%# DataBinder.Eval(Container.DataItem, "数据字段1")%>’ & name=’<%# DataBinder.Eval(Container.DataItem, "数据字段2")%>’ /> {twf7.eY
T</gWW
7.表格点击改变颜色 E&=?\KM
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) y")>"8H
{ G&B}jj
e.Item.Attributes.Add("onclick","this.style.backgroundColor=’#99cc00’; X%qR6mMfT7
this.style.color=’buttontext’;this.style.cursor=’default’;"); x{w ?X.Nt
} ph. :~n>z
Rf$6}F
写在DataGrid的_ItemDataBound里 eHZl-|-
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) [?(W7
{ n_gB#L$
e.Item.Attributes.Add("onmouseover","this.style.backgroundColor=’#99cc00’; x}24?mP
this.style.color=’buttontext’;this.style.cursor=’default’;"); um4zLsd#v
e.Item.Attributes.Add("onmouseout","this.style.backgroundColor=’’;this.style.color=’’;"); h*'5h!
} ~|jy$*m4A
.Zm }
aYX '&k

8.关于日期格式 ?-p aM5Q+
"K=)J'/n
日期格式设定 0pG(+fN_9
DataFormatString="{0:yyyy-MM-dd}" 0|k[Wha#
aPMM:RP`
我觉得应该在itembound事件中 U9%nku4
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) /R?uxhV
:H k4i%hGk
9.获取错误信息并到指定页面 2Nzcej
1e%Xyqb
不要使用Response.Redirect,而应该使用Server.Transfer M& L0n%,y5
MH(g<4>*
e.g >sY+Y 22U
// in global.asax dXN&<Q,
protected void Application_Error(Object sender, EventArgs e) { WWzns[$f
if (Server.GetLastError() is HttpUnhandledException) vUExS Z^
Server.Transfer("MyErrorPage.aspx"); O\{_)L
zL}DLfy>R
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) uU"s50m
} V,,iKr@TG
p{GDW_
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 ~UFsi VpL

10.清空Cookie 61 |xv_/
Cookie.Expires=[DateTime]; {[iQRYD0|
Response.Cookies("UserName").Expires = 0 ioQlC4Y
