1. 打开新的窗口并传送参数: usOx=^?=
MzTW8
传送参数: `ZGcgO<c\
response.write("<script>window.open(’*.aspx?id="+this.DropDownList1.SelectIndex+"&id1="+...+"’)</script>") (Uk,
n%$ &=-Fk
接收参数: [ee30ELn
string a = Request.QueryString("id"); mX\
;oV!
string b = Request.QueryString("id1"); B9M>e'H%<
nPA@h
2.为按钮添加对话框 ]b}B2F'n
Button1.Attributes.Add("onclick","return confirm(’确认?’)"); &erm`Ho
button.attributes.add("onclick","if(confirm(’are you sure...?’)){return true;}else{return false;}") DDw''
(-"`,8K 2}
3.删除表格选定记录 pbn\9C/
int intEmpID = (int)MyDataGrid.DataKeys[e.Item.ItemIndex]; y=H@6$2EQ
string deleteCmd = "DELETE from Employee where emp_id = " + intEmpID.ToString() >n$!<
!buz<h
4.删除表格记录警告 %Kto.Xq

5.点击表格行链接另一页 P))^vUt~
private void grdCustomer_ItemDataBound(object sender, System.Web.UI.WebControls.DataGridItemEventArgs e) FFzH!=7T?
{ i_l+:/+G+
//点击表格打开 7z'ha?
if (e.Item.ItemType == ListItemType.Item || e.Item.ItemType == ListItemType.AlternatingItem) ~F[L4y!sL
e.Item.Attributes.Add("onclick","window.open(’Default.aspx?id=" + e.Item.Cells[0].Text + "’);"); !7 _\P7M

★特别注意:【?id=】 处不能为 【?id =】 Ly #_?\bn
6.表格超连接列传递参数 AsxD}Nw[Z*
<asp:HyperLinkColumn Target="_blank" headertext="ID号" DataTextField="id" NavigateUrl="aaa.aspx?id=’ o8S"&O
?
<%# DataBinder.Eval(Container.DataItem, "数据字段1")%>’ & name=’<%# DataBinder.Eval(Container.DataItem, "数据字段2")%>’ /> n=!uNu7
/QxlGfNZ
7.表格点击改变颜色 #oV+@D`
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) p'Bm8=AwD
{ ,8VU&?`<}
e.Item.Attributes.Add("onclick","this.style.backgroundColor=’#99cc00’; a!,r46>$H
this.style.color=’buttontext’;this.style.cursor=’default’;"); oF|N O^H
} n WaNT-
gH7z
写在DataGrid的_ItemDataBound里 APSgnf
if (e.Item.ItemType == ListItemType.Item ||e.Item.ItemType == ListItemType.AlternatingItem) >l5u54^3K
{ Yl({)qK{
e.Item.Attributes.Add("onmouseover","this.style.backgroundColor=’#99cc00’; ;=~Xr"(/z
this.style.color=’buttontext’;this.style.cursor=’default’;"); k1}hIAk3u
e.Item.Attributes.Add("onmouseout","this.style.backgroundColor=’’;this.style.color=’’;"); 2<r\/-#pU
} #R5U

8.关于日期格式 |b.z*G
PCE4W^ns
日期格式设定 *e{PxaF!C
DataFormatString="{0:yyyy-MM-dd}" LU2waq}VA
+%#8k9Y
我觉得应该在itembound事件中 ;Icixu'O
e.items.cell["你的列"].text=DateTime.Parse(e.items.cell["你的列"].text.ToString("yyyy-MM-dd")) X6@w krf-
!G?gsW0\h
9.获取错误信息并到指定页面 M+Uyb7
%1}6q`:w
不要使用Response.Redirect,而应该使用Server.Transfer K-Mc6
aMwB>bt
e.g 63&^BW
// in global.asax H lB]38
protected void Application_Error(Object sender, EventArgs e) { P+(i^=S
if (Server.GetLastError() is HttpUnhandledException) wL{qD
Server.Transfer("MyErrorPage.aspx"); S~yR5cb
j8$Zv%Ca%
//其余的非HttpUnhandledException异常交给ASP.NET自己处理就okay了 :) @;^Y7po6u
} 8]"(!i_;)
r4{<Z3*N
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 ")UwkF
~[W#/kd1n
10.清空Cookie s"~5']8
Cookie.Expires=[DateTime]; N4{nG,Mo]
Response.Cookies("UserName").Expires = 0 s] au/T6b
