2.为按钮添加对话框 w(QU '4~
Button1.Attributes.Add("onclick","return confirm(’确认?’)"); (RR:{4I
button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") >xU$)uE&

3.删除表格选定记录 @hlT7C)xK
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; UN
<s1
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() =rA "|=

5.点击表格行链接另一页 'u6T^Y S
private void grdCustomer_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e) mXd,{b'

//点击表格打开 WgxGx`Y)

双击表格连接到另一页 kiLwN

6.表格超连接列传递参数 f)`_su
U
<asp:HyperLinkColumn Target="_blank" headertext="ID号" DataTextField="id" NavigateUrl="aaa.aspx?id=’ \LYB% K}
<%# DataBinder.Eval(Container.DataItem, "数据字段1")%>’ & name=’<%# DataBinder.Eval(Container.DataItem, "数据字段2")%>’ /> 4e6x1`Y{xB

7.表格点击改变颜色 KxyD{W1
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) N/wU P
{ X$aN:!1
e.Item.Attributes.Add("onclick","this.style.backgroundColor=’#99cc00’; F't4Q
this.style.color=’buttontext’;this.style.cursor=’default’;"); bC_qoI<
} K(&I8vAp
KIY/nu
写在DataGrid的_ItemDataBound里 tPv3nh
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) dQX<X}
{ 5*M3sN
e.Item.Attributes.Add("onmouseover","this.style.backgroundColor=’#99cc00’; >?-etl

e.Item.Attributes.Add("onmouseout","this.style.backgroundColor=’’;this.style.color=’’;"); $AGW8"
} {y5v"GR{YM

8.关于日期格式 !*[Fw1-J
G@Ha
t
日期格式设定 *P\$<4l
DataFormatString="{0:yyyy-MM-dd}" tM&O<6Y
]>j>bHG
我觉得应该在itembound事件中 OVwcjhQ
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) _ELuQ>zM]+
#~3$4j2U(y
9.获取错误信息并到指定页面 iME)Jl&
!V<c:6"
不要使用Response.Redirect,而应该使用Server.Transfer vJybhdvP
I-?PTr
e.g 0\qLuF[)
// in global.asax R,]J~TfPK
protected void Application_Error(Object sender, EventArgs e) { x;Qs_"t];3
if (Server.GetLastError() is HttpUnhandledException) OV@MT^
Server.Transfer("MyErrorPage.aspx"); DrAp&A|WV|
T;7=05k<_
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) 1!(Og~#(
} `^:>sU
r#8t@W
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 1 u[a713O

10.清空Cookie U*P&O+(1'
Cookie.Expires=[DateTime]; pr\wI?:k
Response.Cookies("UserName").Expires = 0 $w,O[PIi
