1. 打开新的窗口并传送参数: h<IPV'1
f!+G1z}iA
传送参数: }#QYZ nR
response.write("<script>window.open(’*.aspx?id="+this.DropDownList1.SelectIndex+"&id1="+...+"’)</script>") y>_*}>2 ,O
$Rv(v%
接收参数: n*vhCeL
string a = Request.QueryString("id"); Ox}a\B8
string b = Request.QueryString("id1"); J={IGA
3q:>NB<
2.为按钮添加对话框 {N 0i
3e
s
Button1.Attributes.Add("onclick","return confirm(’确认?’)"); Vh5Z'4N
button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") 2f7]=snCG

3.删除表格选定记录 zFeo8S
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; /WJ+e
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() R7~#7qKQB

5.点击表格行链接另一页 23~KzC
private void grdCustomer_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e) \S`|7JYW
{ 8S*W+l19f
//点击表格打开 %:hU:+G E
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem) v\b@;H`
e.Item.Attributes.Add("onclick","window.open(’Default.aspx?id=" + e.Item.Cells[0].Text + "’);"); ,T\)%q

双击表格连接到另一页 sDzlNMr?P+

} {Wp5Ane
VwxLElV
★特别注意:【?id=】 处不能为 【?id =】 huw|J<$
6.表格超连接列传递参数 wc.T;(
<asp:HyperLinkColumn Target="_blank" headertext="ID号" DataTextField="id" NavigateUrl="aaa.aspx?id=’ H|i39XV
<%# DataBinder.Eval(Container.DataItem, "数据字段1")%>’ & name=’<%# DataBinder.Eval(Container.DataItem, "数据字段2")%>’ /> J_ S]jE{
?,0 5!]
7.表格点击改变颜色 An0Zg'o!G
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) ?cdjQ@j~h
{ 9XSZD93L
e.Item.Attributes.Add("onclick","this.style.backgroundColor=’#99cc00’; us
TPr
this.style.color=’buttontext’;this.style.cursor=’default’;"); ~Dz`O"X3
} FSn&N2[D
3A>Bnb
写在DataGrid的_ItemDataBound里 <qpDAz4k
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) ap[{`u
{ j9G1
_
e.Item.Attributes.Add("onmouseover","this.style.backgroundColor=’#99cc00’; a2tRmil
this.style.color=’buttontext’;this.style.cursor=’default’;"); :`w'}h7m
e.Item.Attributes.Add("onmouseout","this.style.backgroundColor=’’;this.style.color=’’;"); lyYi2& %
} }E%#g#

8.关于日期格式 Q4vl
FJl_2
日期格式设定 }uaRS9d
DataFormatString="{0:yyyy-MM-dd}" H6I]GcZ$
++)3*+N+
我觉得应该在itembound事件中 S_ Pa .
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) hwR_<'!
)lsR8Hi8
9.获取错误信息并到指定页面 2Yt+[T*
#ovmX
不要使用Response.Redirect,而应该使用Server.Transfer ExDv7St1(k
!uwZ%Uxz
e.g jR[3{ Reo
// in global.asax sS5: 5i
protected void Application_Error(Object sender, EventArgs e) { >|S&@<
if (Server.GetLastError() is HttpUnhandledException) (+^z9p7/!
Server.Transfer("MyErrorPage.aspx"); C%l+<wpXO
S[zX@3eZV
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) 6bXR?0$*M.
} ToVi;
;&N=t64"
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 vL,:Yn@b

10.清空Cookie Xbp~cn
Cookie.Expires=[DateTime]; v3`k?jAaI
Response.Cookies("UserName").Expires = 0 ZFNn(n
