2.为按钮添加对话框 d&u7]<yDA
Button1.Attributes.Add("onclick","return confirm(’确认?’)"); ZBJ3 VK
button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") -w ~(3(

3.删除表格选定记录 b_=8!Q.:
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; FCiq?@
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() 6- ]h5L]

★特别注意:【?id=】 处不能为 【?id =】 4 x,hj
6.表格超连接列传递参数 %l7fR}
<asp:HyperLinkColumn Target="_blank" headertext="ID号" DataTextField="id" NavigateUrl="aaa.aspx?id=’ PLdn#S}.
<%# DataBinder.Eval(Container.DataItem, "数据字段1")%>’ & name=’<%# DataBinder.Eval(Container.DataItem, "数据字段2")%>’ /> kH?#B%N5

7.表格点击改变颜色 DMZ`Sx
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) MEq"}zrh
{ G {b:i8}l
e.Item.Attributes.Add("onclick","this.style.backgroundColor=’#99cc00’; )~
z Z'^
this.style.color=’buttontext’;this.style.cursor=’default’;"); L.B~ax.|Z
} UFEN y."P

写在DataGrid的_ItemDataBound里 A#DR9Eq

{ S LGW:
e.Item.Attributes.Add("onmouseover","this.style.backgroundColor=’#99cc00’; "8(U\KaX
this.style.color=’buttontext’;this.style.cursor=’default’;"); eH

e.Item.Attributes.Add("onmouseout","this.style.backgroundColor=’’;this.style.color=’’;"); 6GINmkA

8.关于日期格式 {/}^D-
B~TN/sd
日期格式设定 #3MKH8k&~
DataFormatString="{0:yyyy-MM-dd}" {TAw)!R~
,2`~ NPb
我觉得应该在itembound事件中 H}nJbnU
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) HZZDv+

9.获取错误信息并到指定页面 8Xn!Kpa
9.&mz}q
不要使用Response.Redirect,而应该使用Server.Transfer 6RK\}@^=K
"!Lkp2\
e.g :a3xvN-l
// in global.asax G7-!`-Nk
protected void Application_Error(Object sender, EventArgs e) { - k`.j
if (Server.GetLastError() is HttpUnhandledException) Gt~JA0+C)7
Server.Transfer("MyErrorPage.aspx"); nQ=aLV+'
qLjT.7 .x
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) z%:1)
} uLV BM]Qj
AyVrk
8G
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 !wh&>3~

10.清空Cookie #a,9B-X
Cookie.Expires=[DateTime]; 9%!dNnUk
Response.Cookies("UserName").Expires = 0 V'StvU
